IBM Spectrum Scale features

IBM Spectrum Scale, the follow-on to IBM GPFS, is a high-performance solution for managing data at scale with the distinctive ability to perform archive and analytics in place.
IBM Spectrum Scale has the following features:

• Uses Declustered RAID, where data and parity information as well as Spare Capacity is distributed across all disks
• Rebuilds with Declustered RAID are faster:
  • Traditional RAID would have one LUN fully busy resulting in slow rebuild and high impact overall
  • Declustered RAID rebuild activity spreads the load across many disks resulting in faster rebuild and less disruption to user programs
  • Declustered RAID minimizes critical data exposed to data loss in case of a second failure.
• 2-fault / 3-fault tolerance and mirroring: 2- or 3-fault-tolerant Reed-Solomon parity encoding as well as 3- or 4-way mirroring provides data integrity, reliability and flexibility
• End-to-end checksum:
  • Helps detect and correct off-track I/O and dropped writes
  • Disk surface to GPFS user/client provides information to help detect and correct write or I/O errors
• Disk hospital – asynchronous, global error diagnosis:
  • If there is a media error, information provided helps in verifying and restoring a media error. If there is a path problem, information can be used to attempt alternate paths.
  • Disk tracking information helps track disk service times, which is useful in finding slow disks so they can be replaced.
• Multipathing: Performed automatically by Spectrum Scale, so no multipath driver is needed. Supports a variety of file I/O protocols:
  • POSIX, GPFS, NFS v4.0, SMB v3.0
  • Big data and analytics: Hadoop MapReduce
  • Cloud: OpenStack Cinder (block), OpenStack Swift (object), S3 (object)
• Supports cloud object storage:
  • IBM Cloud Storage System (Cleversafe) Amazon S3
  • IBM SoftLayer Native Object OpenStack Swift
  • Amazon S3 compatible providers

• The following sections provide information about these configuration steps.

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 400 GB SSDs that are required in the first drive enclosure for any configuration using HDDs. These SSDs are for logtip use by the IBM Spectrum Scale software and are not for customer data.

DSS-G100 configuration: The G100 does not include external drive enclosures. Instead, NVMe drives are installed locally into the server as described in the SR650 configuration section.

The drive requirement are as follows:

• For configurations that use HDDs, two 400GB 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.

IBM Spectrum Scale licensing
IBM Spectrum Scale licensing part numbers are listed in the following table. Licenses for DSS-G are based on the number and type of drives in the configuration and are offered in differing periods of support.
The core offerings available are:

• For configurations with HDDs:
  • IBM Spectrum Scale for DSS Data Management Edition for Disk per Disk Drive
  • IBM Spectrum Scale for DSS Standard Edition for Disk Per Disk Drive
  • Tip: The two mandatory SSDs needed for HDD configurations are not counted in the licensing.
• For configurations with SSDs:
  • IBM Spectrum Scale for DSS Data Management Edition for Flash per Disk Drive
  • IBM Spectrum Scale for DSS Standard Edition for Flash per Disk Drive

Each of these is offered in 1, 3, 4 and 5-year support periods.
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 by the x-config configurator. The total number of Spectrum 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.

Additional licensing information:

• No additional licenses (for example, client or server) are needed for Spectrum Scale for DSS. Only licenses based on the number of drives (non-logtip) are needed.
• For non-DSS storage in the same Cluster (for example, separated metadata on traditional controller-based storage), you have the option of socket-based licenses (Standard Edition only) or capacity-
• based (per TB) licenses (Data Management Edition only).
• It is possible to mix traditional GPFS/Spectrum Scale storage licensed per socket and new Spectrum Scale storage licensed per drive, however the drive-based license is only available with DSS-G.
• As long as a Spectrum Scale client accesses storage that is licensed per socket (either cross-
• cluster/remote or locally), it will also require a socket based client/server license.
• It is not supported to mix Standard Edition and Data Management Edition licensing within a cluster.
• Drive-based Spectrum Scale for DSS licenses are not transferrable from one DSS-G configuration to another. The license is attached to the storage/machine it is sold with.
