Product Guide

Lenovo Distributed Storage Solution for IBM Storage Scale (DSS-G) is a software-defined storage (SDS) solution for dense scalable file and object storage suitable for high-performance and data-intensive environments. Enterprises or organizations running HPC, AI, Big Data or cloud workloads will benefit the most from the DSS-G implementation. DSS-G combines the performance of Lenovo ThinkSystem SR655 V3 2U servers with an AMD EPYC 9004 Series processor, Lenovo storage enclosures, and industry leading IBM Storage Scale software, to offer a high performance, scalable building block approach to modern storage needs.

Lenovo DSS-G is delivered as a pre-integrated, easy-to-deploy rack-level engineered solution that dramatically reduces time-to-value and total cost of ownership (TCO). The solution is built on Lenovo ThinkSystem SR655 V3 servers, Lenovo Storage D1224 Drive Enclosures with high-performance 2.5- inch SAS SSDs, and Lenovo Storage D4390 High-Density Drive Enclosures with large capacity 3.5-inch NL SAS HDDs. Combined with IBM Storage Scale (formerly IBM Spectrum Scale or General Parallel File System, GPFS), an industry leader in high-performance clustered file system, you have an ideal solution for the ultimate file storage solution for HPC, AI& Big Data.

Did you know?

DSS-G with ThinkSystem V3 is more than doubling the performance over the previous generation and supports up to 25% more capacity in a single building block. Lenovo DSS-G can be licensed by the number of drives installed or alternatively the usable capacity, rather than the number of processor cores or the number of connected clients, so there are no added licenses for other servers or clients that mount and work with the file system. Lenovo DSS-G with storage enclosures supports online enclosure expansion.

This enables a customer to grow the number of enclosures in an existing DSS-G building block without bringing down the file system, maximizing flexibility to scale storage capacity based on need. With available Lenovo Premier Support Services, Lenovo provides a single point of entry for supporting the entire DSS-G solution, including the IBM Storage Scale software, for quicker problem determination and minimized downtime.

IBM Storage Scale

IBM Storage Scale, based on IBM General Parallel File System (GPFS) technology, is a high-performance and highly scalable parallel file system with an extensive suite of enterprise class data management features. IBM Storage Scale was previously known as IBM Spectrum Scale. Lenovo is a strategic alliance partner of IBM, and combines IBM Storage Scale software with Lenovo servers, storage and networking components for integrated and customized solutions.

IBM Storage Scale offers access to a single file system or set of filesystems from multiple nodes that can be SAN-attached, network attached or a mix of both or even in a shared nothing cluster configuration. It provides a global namespace, shared file system access among IBM Storage Scale clusters, simultaneous file access from multiple nodes, high recoverability and data availability through replication, the ability to make changes while a file system is mounted, and simplified administration even in large environments. When integrated as part of the Lenovo DSS-G system, the Storage Scale Native RAID code (GNR) is used to provide a fully software defined IBM Storage Scale solution.

Lenovo DSS-G supports two editions of IBM Storage Scale:

• IBM Storage Scale Data Access Edition (DAE) provides base GPFS functions including Information Lifecycle Management (ILM), Active File Management (AFM), and Clustered NFS (CNFS) in Linux environments.
• IBM Storage Scale Data Management Edition (DME) provides all the features of the Data Access Edition plus advanced features like asynchronous multi-site disaster recovery, native encryption support, Transparent Cloud Tiering.

Storage Scale RAID on Data Access

Storage Scale RAID on Data Access and Data Management Edition

IBM Storage Scale RAID (also known as GNR) integrates the functionality of an advanced storage controller into the GPFS NSD server. Unlike an external storage controller, where configuration, LUN definition, and maintenance are beyond the control of IBM Storage Scale, IBM Storage Scale RAID itself takes on the role of controlling, managing, and maintaining physical disks – hard disk drives (HDDs) and solid-state drives (SSDs).

Sophisticated data placement and error correction algorithms deliver high levels of storage reliability, availability, serviceability, and performance. IBM Storage Scale RAID provides a variation of the GPFS network shared disk (NSD) called a virtual disk, or vdisk. Standard NSD clients transparently access the vdisk NSDs of a file system using the conventional NSD protocol. The features of IBM Storage Scale RAID include:

• Software RAID
  • IBM Storage Scale RAID, which runs on standard Serial Attached SCSI (SAS) disks in a dual-ported JBOD array, does not require external RAID storage controllers or other custom hardware RAID acceleration.
• Declustering
  • IBM Storage Scale RAID distributes client data, redundancy information, and spare space uniformly across all disks of a JBOD. This approach reduces the rebuild (disk failure recovery process) overhead and improves application performance compared to conventional RAID.
• Pdisk-group fault tolerance
  • In addition to declustering data across disks, IBM Storage Scale RAID can place data and parity information to protect against groups of disks that, based on characteristics of a disk enclosure and system, could possibly fail together due to a common fault. The data placement algorithm ensures that even if all members of a disk group fail, the error correction codes will still be capable of recovering damaged data.
• Checksum
  • An end-to-end data integrity check, using checksums and version numbers, is maintained between the disk surface and NSD clients. The checksum algorithm uses version numbers to detect silent data corruption and lost disk writes.
• Data redundancy
  • IBM Storage Scale RAID supports highly reliable 2-fault-tolerant and 3-fault-tolerant Reed-Solomonbased parity codes and 3-way and 4-way replication.
• Large cache
  • A large cache improves read and write performance, particularly for small I/O operations.
• Arbitrarily-sized disk arrays
  • The number of disks is not restricted to a multiple of the RAID redundancy code width, which allowsflexibility in the number of disks in the RAID array.
• Multiple redundancy schemes
  • One disk array can support vdisks with different redundancy schemes, for example Reed-Solomon and replication codes.
• Disk hospital
  • A disk hospital asynchronously diagnoses faulty disks and paths, and requests replacement of disks by using past health records.
• Automatic recovery
  • Seamlessly and automatically recovers from primary server failure.
• Disk scrubbing
  • A disk scrubber automatically detects and repairs latent sector errors in the background.
• Familiar interface
  • Standard IBM Storage Scale command syntax is used for all configuration commands, including maintaining and replacing failed disks.
• Flexible hardware configuration
  • Support of JBOD enclosures with multiple disks physically mounted together on removable carriers.
• Journaling
  • For improved performance and recovery after a node failure, internal configuration and small-write data are journaled to solid-state disks (SSDs) in the JBOD or to non-volatile random-access memory (NVRAM) that is internal to the IBM Storage Scale RAID servers.

Refer to the Lenovo 1U Switched & Monitored 3-Phase PDUs product guide for more information on preferred orientation of Lenovo rack PDUs: https://lenovopress.lenovo.com/lp1556-lenovo-1u-switched-monitored-3-phase- pdu

Configurations

Drive Enclosure configuration

All drives used in all the enclosures in a DSS-G configuration are identical. The only exception to this is a pair of 800 GB SSDs that are required in the first drive enclosure for any configuration using HDDs. These SSDs are for logtip use by the IBM Storage Scale software and are not for user data.

The drive requirement are as follows:

• For configurations that use HDDs (D4390 only), two 800GB logtip SSDs must also be selected in the first drive enclosure in the DSS-G configuration.
• All subsequent enclosures in HDD-based DSS-G configuration do not require these logtip SSDs.
• Configurations using SSDs do not require the pair of logtip SSDs.
• Only one drive size & type is selectable per DSS-G configuration.
• All drive enclosures must be fully populated with drives. Partially filled enclosures are not supported.

The following table lists the drives available for selection in a D1224 enclosure. D1224 configurations are all SSDs and do not require separate logtip drives.

D4390 configurations are all HDDs, as follows:

• First D4390 enclosure in a configuration: 88 HDDs + 2x 800GB SSDs (BT4S)
• Subsequent D4390 enclosures in a configuration: 90x HDDs

Guaranteed Quality: Lenovo DSS-G is working exclusively with Enterprise grade hard drives. Where common drives are only rated at up to 180 TB/year, the Lenovo Enterprise drives are always warranted to up to 550TB/year.

Mixing D4390 and D3284 enclosures: DSS-G configurations cannot have mixed hard disk enclosures. A DSS-G system based on ThinkSystem SR650 V2 and D3284 enclosures cannot be expanded by adding D4390 enclosures. The D3284 is not supported for DSS-G when using ThinkSystem SR655 V3 configurations therefore an existing DSS-G building block cannot be retrofitted with ThinkSystem SR655 V3 NSD servers.

SR655 V3 configuration

The Lenovo DSS-G configurations described in this product guide use the ThinkSystem SR655 server, which features the AMD Family processors. Details about the configurations are in the Specifications section.

• SR655 V3 memory
• SR655 V3 internal storage
• SR655 V3 SAS HBAs
• SR655 V3 network adapter

SR655 V3 memory

The DSS-G offerings allow three different memory configurations for the SR655 V3 servers

• 384 GB using 12x 32 GB TruDDR5 RDIMMs (1 DIMM per memory channel)
• 768 GB using 12x 64 GB TruDDR5 RDIMMs (1 DIMM per memory channel)
• 1536 GB using 12x 128 GB TruDDR5 RDIMMs (1 DIMM per memory channel)

The following tables indicates memory requirements on the DSS-G configurations containing D4390 enclosures for different drive capacities. This table assumes a 16MB block size and RAID level of 8+2P. If your use configuration deviates from these parameters, please check with your Lenovo sales representative for the required memory.

Use of smaller block sizes on the DSS-G systems will require more memory. When selecting memory sizing, it is not always best to go larger than required – the 128GB DIMMs are both more expensive and 4 rank which can impact memory performance. Future larger drive capacities may require different memory configurations. The Lenovo configurator will automatically scale memory based on the selection of file system block size, drive capacity and drive count.

The transceivers and optical cables, or the DAC cables needed to connect the adapters to the customersupplied network switches can be configured together with the system in x-config. Consult the Product Guides for the adapters for details. The following table lists the OCP LOM modules that are available for use for deployment/OS network.

Table 18:  Supported OCP adapters

DSS-G supported network adapters are required in slots 1 and 7, and the SAS adapters are always located in slots 2, 4, 5, and 8, as shown in the following figure.

Cluster network

The Lenovo DSS-G offering connects as a storage block to the customer’s Storage Scale cluster network using the high-speed network adapters installed in the servers. Each pair of servers has two or three network adapters, which are either Ethernet or InfiniBand. Each DSS-G storage block connects to the cluster network. In concert with the cluster network is the Confluent management network. In lieu of a customer-supplied management network, the Lenovo DSS-G offering includes a ThinkSystem SR635 V3 server running Confluent and a NVIDIA Networking SN2201 48-port Gigabit Ethernet switch. These components are shown in the following figure.

Red Hat Enterprise Linux

The SR655 V3 servers run Red Hat Enterprise Linux which is preinstalled on the RAID-1 pair of 300 GB drives installed in the servers. Each server requires a Lenovo RHEL Premium Support subscription. The subscription provides Level 1 and Level 2 support, with 24×7 for Severity 1 situations.

Table 19:  Operating system licensing

7S0F0005WW| S0N9| RHEL Server Physical or Virtual Node, 2 Skt Premium Subscription w/Lenovo Support 3Yr
7S0F0006WW| S0NA| RHEL Server Physical or Virtual Node, 2 Skt Premium Subscription w/Lenovo Support 5Yr

Lenovo recommended customers have RHEL Extended Update Support (EUS) enabled which provides critical patches for the LTS release of RHEL installed on the DSS-G systems. EUS is included with x86-64 Red Hat Enterprise Linux Server Premium subscriptions.

IBM Storage Scale licensing

DSS-G can be configured with two types of license models:

• Per Disk/Flash Drive
  • The number of licenses needed is based on the total number of HDDs and SSDs in the drive enclosures (excluding the logTip SSDs) and will be derived automatically by the configurator.
  • This License model is available for the Data Access Edition and the Data Management Edition.
• Per managed capacity
  • The number of licenses needed is based on the storage capacity being managed in an IBM Storage Scale cluster and will also be derived automatically by the configurator based on the selection of parity level made. The storage capacity to be licensed is the capacity in Tebibytes (TiB) from all Network Shared Disk (NSDs) in the IBM Storage Scale cluster after applying IBM Storage Scale RAID. The capacity to be licensed is not affected by using functions such as replication or compression or by doing tasks such as creating or deleting files, file systems, or snapshots. This License model is available for the Data Access Edition, the Data Management Edition, and the Erasure Code Edition.

Each of these is offered in 1, 3, 4 and 5-year support periods. The total number of Storage Scale licenses needed will be split between the two DSS-G servers. Half will appear on one server and half will appear on the other server. The license however relates to the total solution and storage drives/capacity within.

Additional licensing information

• No additional licenses (for example, client or server) are needed for Storage Scale for DSS. Only licenses based on the number of drives (non-logtip) or capacity in TebiBytes (TiB) after applying IBM Storage Scale RAID are needed.
• Capacity licensing is measured on Binary format (1 TiB = 2^40 Bytes), which means that you must multiply the nominal Decimal format (1TB = 10^12 Bytes) chosen by drive vendors with 0.9185 to get to the actual capacity to be licensed. For DSS-G the Lenovo configurator will take care of that for you.
• For non-DSS Lenovo storage in the same Cluster (for example, separated metadata on traditional controller-based storage), you have the same options of capacity-based per Disk/Flash drive or per TiB licenses.
• It is not supported to mix Data Access Edition and Data Management Edition licensing within a cluster.
• You can expand a Data Access Edition or a Data Management Edition cluster with Erasure Code Edition systems. The limitations of Data Access Edition features apply if expanding a Data Access Edition cluster.
• Disk/Flash drive-based Storage Scale licenses can only be transferred from the existing Lenovo storage solution that is being decommissioned and re-used on its equivalent future or replacement Lenovo storage solution.
• Existing capacity licenses through for example an Enterprise License Agreement with IBM can be applied to Lenovo DSS-G after providing Proof of Entitlement. While Lenovo provides the solution level support, software support needs to be requested from IBM directly in such a case. When configuring a system using an ELA, at least 1 Lenovo Storage Scale license should be attached to the configuration to ensure customer entitlement via the Lenovo download portal functions correctly.
• Lenovo sub-contracts the L1/L2 support for IBM Storage Scale to IBM for Lenovo supplied licenses. Where a customer has premier support on the solution, they can raise a service call with Lenovo whowill raise a call with IBM if required. Where a customer does not have Premium support on the DSS-G solution, the customer uses the IBM service portal to directly raise support questions for IBM Storage Scale support.

Lenovo Confluent support

Lenovo’s cluster management software, Confluent, is used to deploy Lenovo DSS-G systems. Whilst Confluent is an open source software package, support for the software is chargeable. Support for each DSSG server and any support nodes is normally included in the configuration.

Table 21:  Lenovo Confluent support

Lenovo EveryScale factory integration for DSS-G

Lenovo manufacturing implements a robust testing and integration program to ensure Lenovo EveryScale components are fully operational when shipped out of the factory. In addition to the standard component level validation performed on all hardware components produced by Lenovo, EveryScale performs rack level testing to verify that the EveryScale cluster operates as a solution. The rack level testing and validation includes the following:

• Performing a power on test. Assure device power is present, with no error indicators
• Set up RAID (when required)
• Set up storage devices and verify functionality
• Validate network connectivity and functionality
• Verify functionality of server hardware, network infrastructure, and server configuration correctness.

Customized installation services beyond the basic Lenovo Hardware Installation services are also available to meet the specific needs of the client and for solutions with Client Site Integration Kit.

Before installation, the client should complete the following steps to ensure the hardware will be successfully installed:

• Backing up the data being migrated to the new hardware
• Ensuring the new hardware is available and in place
• Assign a technical lead to act as liaison with Lenovo, who can coordinate access to other resources if required
• Designated data center location has the required power and cooling in place to support purchased solution
• Providing a safe workspace and appropriate access for the technician

Once the client is ready, an expert technician will perform the basic Lenovo Hardware Installation services.

This process will include the following:

• Verify receipt and condition of all rack(s) and components
• Verify the client environment is ready for consequent installation
• Unpack and visually inspect hardware for damage
• Place rack(s) and complete installation and inter-rack cabling as specified by the solution configuration
• Connect the equipment to customer-supplied power
• Ensure the equipment is operational: Power on equipment, check for green lights and obvious issues
• Remove packaging and other waste materials to the customer designated dumpster
• Provide completion form for customer to authorize
• If a hardware failure occurs during the installation, service call will be opened.

Additional client requirements beyond the basic Lenovo Hardware Installation services scope, can be offered with customized installation services sized specifically to the client’s needs.To get operational a final onsite software installation and configuration for the specific environment is required. Lenovo can also provide comprehensive onsite configuration of software, including integration and validation for operating systems and software, virtualization and high-availability configurations. For additional information, see the Services section.

Client Site Integration Kit onsite installation

Besides shipping fully integrated into the Lenovo 1410 rack cabinet, DSS-G solution gives clients the choice of shipping with the Lenovo Client Site Integration Kit (7X74) which allows clients to have Lenovo or a business partner install the solution in a rack of their own choosing. The Lenovo Client Site Integration Kit enables clients to gain the interoperability warranty benefit of an integrated DSS-G solution while also providing them flexibility in custom-fitting into the client datacenter.

With the Lenovo Client Site Integration Kit, the DSS-G solution is built and tested at the racklevel in Lenovo manufacturing just like described for factory integration above. Afterwards it is disassembled again, and Servers, switches and other items are packaged in individual boxes with a ship group box for cables, publications, labeling, and other rack documentation. Clients are required to purchase installation services from Lenovo or a business partner for the physical setup. The installation team will install the solution at the customer site into the customer provided rack per racking diagrams and point-to-point instructions. The Client Side Integration Kit includes a “virtual” rack serial number for the DSS-G solution. This virtual rack serial number is used when raising service calls against the DSS-G solution. To get operational a final onsite software installation and configuration for the specific environment is required. Lenovo can also provide comprehensive onsite configuration of software, including integration and validation for operating systems and software, virtualization and high- availability configurations. For additional information, see the Services section.

Lenovo EveryScale Interoperability Support for DSS-G

On top of their individual warranty and maintenance scope or support entitlement, EveryScale offers solutionlevel interoperability support for HPC and AI configurations based on the above selection of Lenovo ThinkSystem portfolio and OEM components. The extensive testing results in a “Best Recipe” release of software and firmware levels Lenovo warrants to  work seamlessly together as a fully integrated data center solution instead of a collection of individualcomponents at the time of implementation.

To see the latest Best Recipe for Scalable Infrastructure at Lenovo, see the following link: https://support.lenovo.com/us/en/solutions/HT505184#5

The Solution Support is engaged by opening a hardware ticket based on the EveryScale Rack (Model 1410)or EveryScale Client Site Integration Kit (Model 7X74). The EveryScale Support team then will triage the issue and recommend next steps for you, including potentially to open tickets with other components of the solution.

For issues that require debugging beyond hardware and firmware (Driver, UEFI, IMM/XCC) an additional ticket will have to be opened with the software vendor (e.g. Lenovo SW Support or 3rd party SW vendor) to assist working towards a fix. The EveryScale Support team will then work with the SW Support team in isolating root cause and fixing the defect. For more information about opening tickets, as well as the scope of support for different EveryScale components, see the Lenovo Scalable Infrastructure Support Plan information page .

When a cluster ships the most recent Best Recipe is its compliant version, which is always defined exactly for that specific Scalable Infrastructure release and the cluster is delivered as a solution of that specific release. Using a Support call clients can request a review if their solution is also compatible with a newer Best Recipe release and if it is, are able to upgrade to that while maintaining solution interoperability support. As long as a cluster (Model 1410, 7X74) is under Lenovo warranty or maintenance entitlement, full solution interoperability support will be provided for the original Best Recipes. Even when newer Best Recipes are available the previous Recipe will remain valid and supported.

Of course, any client is free to choose to not adhere to the Best Recipe and instead deploy different software and firmware versions or integrate other components that were not tested for interoperability. While Lenovo cannot warrant interoperability with those deviations from the tested scope, a client continues to receive full break & fix support for the components based on the individual warranty and maintenance entitlement of the  components. This is comparable to the level of support clients will receive when not buying it as a EveryScalesolution, but building the solution from individual components – so-called “roll your own” (RYO).

In those cases, to minimize risk we suggest still staying as close as possible to the Best Recipe even when deviating. We also suggest when deviating first to test it on a small portion of the cluster and only roll it out completely if this test was stable. For clients who need to upgrade the firmware or software of a component – for example due to OS entitlement support issues or Common Vulnerabilities and Exposures (CVE) fixes – that is part of the best recipe, a support call should be placed on the 1410/7X74 rack and serial number. Lenovo product engineering will review the proposed changes, and advise the client on the viability of an upgrade path. If an upgrade can be supported and is performed, EveryScale will note the change in the support records for the solution.
