ThinkSystem RAID 940 Series Internal RAID Adapters

The ThinkSystem RAID 940 family of PCIe 4.0 12 Gbps SAS RAID controllers are high-performance RAIDon-chip (ROC) server adapters for connectivity to drives internal to the server. These adapters support RAID levels 0, 1, 10, 5, 50, 6, and 60, and include an extensive list of RAS and management features.
The ThinkSystem RAID 940-16i is shown in the following figure.

Figure 1. ThinkSystem RAID 940-16i 8GB Flash PCIe Gen4 12Gb Adapter

Did you know?
The RAID 940 Series adapters all have a PCIe 4.0 host interface which doubles the bandwidth between the server and the adapter, compared to the previous generation RAID 930 adapters. This improves the overall performance of the storage subsystem by supporting up to 3 million IOPS (JBOD mode) and up to 3 million IOPS in RAID (random reads).
RAID on Chip-based controllers such as the RAID 940 adapters have a dedicated processor that offloads all RAID functions from the server’s CPU. With hardware acceleration for RAID 5 and 6 operations plus up to 8 GB of dedicated memory for caching, the 940-8i, 16i, and 32i offer the ultimate performance for ThinkSystem servers.

Features

The ThinkSystem RAID 940 adapters have the following standard features:

• NVMe drive support
  The 8-port and 16-port adapters offer Tri-Mode (or Trimode) which enables the use of SAS, SATA, and NVMe U.3 drives at the same time. NVMe drives are connected via a PCIe x1 link to the controller. Such support provides greater flexibility and allows the use of the low-latency and high- IOPS benefits of NVMe drives connected to a standard RAID adapter. Note that only NVMe drives with a U.3 interface are supported with Tri-Mode; U.2 drives are not supported.

• MegaRAID FastPath SSD performance acceleration
  MegaRAID FastPath software provides high-performance I/O acceleration for SSD- based virtual drives by using a low latency I/O path to increase the maximum I/O per second (IOPS) capability of the controller. This feature boosts the performance of applications with a highly random data storage access pattern, such as transactional databases.

• MegaRAID flash cache protection
  MegaRAID flash cache protection uses NAND flash memory, which is powered by a CacheVault Power Module supercapacitor, to protect data that is stored in the controller cache. This module eliminates the need for a lithium-ion battery, which is commonly used to protect DRAM cache memory on PCI RAID controllers. To avoid the possibility of data loss or corruption during a power or server failure, flash cache protection technology transfers the contents of the DRAM cache to NAND flash using power from the offload power module. After the power is restored to the RAID controller, the content of the NAND flash is transferred back to the DRAM, which is flushed to the disk.

• Auto-resume on array rebuild or array reconstruction after the loss of system power
  Auto-resume uses non-volatile RAM (NVRAM) to save the rebuild progress during a host reboot or power failure to automatically resume from the last checkpoint. Auto-resume ensures that data integrity is maintained throughout the process. The card supports a number of features that can be implemented without rebooting the server. Applications, such as email and web servers, benefit from avoiding downtime during the transition.

• Online Capacity Expansion
  Online Capacity Expansion (OCE) allows the capacity of a virtual disk to be expanded by adding new physical disks or making use of unused space on existing disks, without requiring a reboot.

• Online RAID Level Migration
  Online RAID Level Migration (RLM), which is also known as logical drive migration, can migrate a virtual disk from any RAID level to any other RAID level without requiring a reboot. System availability and application functionality remain unaffected.

• Fast initialization for quick array setup
  Fast initialization quickly writes zeros to the first and last sectors of the virtual drive. This feature allows you to immediately start writing data to the virtual drive while the initialization is running in the background.

• Consistency check for background data integrity
  Consistency check verifies that all stripes in a virtual disk with a redundant RAID level are consistent. The consistency check mirrors data when an inconsistent stripe is detected for RAID 1 and re-creates the parity from the peer disks for RAID 5 or RAID 6. Consistency checks can be scheduled to take place periodically.

• Extensive online configuration options and advanced monitoring and event notification
  Management tools provide convenience for the configuration of logical volumes and alerting when errors have occurred or are about to occur.

• Patrol read for media scanning and repairing
  Patrol read is a background sentry service that proactively discovers and corrects media defects (bad sectors) that arise normally as a disk drive ages. The service issues a series of verified commands, and if a bad block is discovered, the card’s firmware uses RAID algorithms to re-create the missing data and remap the sector to a good sector. The task is interruptible based on controller activity and host operations. The firmware also provides an interface where the patrol read task can be initiated, set up for continuous operation, and terminated from a management application. Patrol read can be activated by a manual command or automatically.

• Global and dedicated hot spare with revertible hot spare support
  A hot spare rebuilds data from all virtual disks within the disk group in which it is configured. You can define a physical disk as a hot spare to replace a failed drive. Hot spares can be configured as either global or dedicated. A global hot spare allows any physical drive to be designated as a hot spare. A dedicated hot spare allows the user to assign a hot spare drive to a particular array of the same drive type.

• Drive roaming
  Drive roaming occurs when the physical disks are changed to different ports on the same controller. When the drives are placed on different channels, the controller detects the RAID configuration from the configuration data on the drives.

• MegaRAID SafeStore support for self-encrypting drive (SED) services
  MegaRAID SafeStore encryption services offer instant secure erase and local key management for self-encrypting drives. This technology represents a step forward in securing data on a disk drive from any unauthorized access or modification resulting from theft, loss, or repurposing of drives.
  Instant secure erase permanently removes data when repurposing or decommissioning SEDs. SafeStore local key management provides the necessary management and protection of SEDs by using a simple pass phrase, security key identifier, and security key file that can be set and applied to all SEDs that are assigned to a RAID adapter. This feature removes the complexity of managing each SED’s unique encryption key, and it essentially relieves the administrator of most of the daily tasks of securing data.

• Hardware Secure Boot
  The onboard controller incorporates advanced security through hardware secure boot. The hardware secure boot feature permits only authenticated firmware to execute on the adapter. The controller’s Internal Boot ROM establishes an initial Root of Trust (RoT). Hardware secure boot authenticates and builds a Chain of Trust (CoT) with succeeding firmware images using the RoT meaning only authorized firmware is executed on the adapter. Lenovo provides the signed firmware images making the use of hardware secure boot transparent to customers while providing confidence in the security of the solution.

• XClarity Provisioning Manager for pre-boot array configuration and management
  Provisioning Manager is the ThinkSystem UEFI-based application that includes a RAID setup wizard to help you configure drive groups and virtual disks before installing or booting the operating system.

• XClarity Controller web interface for remote storage management
  XClarity Controller (CXC) is the systems management processor integrated into all ThinkSystem servers. The CXC web interface allows you to perform storage inventory, create and edit virtual disks, view events, import a new controller configuration, and perform firmware updates on the adapter.

Note: MegaRAID CacheCade and MegaRAID Storage Manager are not supported.
