Lenovo ServeRAID M5225-2GB - storage controller (RAID) - SATA 6Gb/s / SAS 12Gb/s - PCIe 3.0 x8

The ServeRAID M5225-2GB SAS/SATA Controller is a 12 Gb SAS RAID controller with two external connectors to connect to SAS expansion enclosures. The adapter is part of the ServeRAID M Series family, which offers a complete server storage solution that consists of RAID controllers, cache/flash modules, energy packs, and software feature upgrades in an ultra-flexible offerings structure. These products are optimized to deliver performance that is demanded by the ever-growing I/O requirements of today's enterprises. The M5225-2GB is a small form factor PCIe RAID adapter for external storage, and it shares a common set of ServeRAID M Series Features on Demand (FoD) upgrades that are available for the entire family.



Key Features
  • Stand-alone RAID adapter with support for RAID 0, 1, 5, 10, and 50 in an x8 lane PCI Express 3.0 low-profile MD2 form factor
  • Two (x4) external mini-SAS HD connectors with eight lanes of 12 Gbps SAS
  • 72-bit 1866 MHz DDR3 cache for enterprise performance
  • Flash-backed-cache-offload with a long-life energy source in case of an unexpected power outage
  • Upgradeable features to enable RAID 6 and 60, performance optimization, and caching with SSDs



Product Features
  • 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 server, 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 the physical disks or making use of unused space on existing disks, without requiring a reboot.
  • Online RAID Level Migration
    Online RAID Level Migration, 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 occur 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 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 verify 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 in which the patrol read task can be started, 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. ServeRAID can define a physical disk as a hot spare to replace a failed drive. Hot spares can be configured as 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.
  • Human Interface Infrastructure (HII) utility for pre-boot array configuration and management
    HII is a utility that is built into the ServeRAID controller that allows you to configure drive groups and logical drives before installing or booting the operating system.
  • MegaRAID Storage Manager management software
    MegaRAID Storage Manager is an easy-to-use advanced RAID management application that is used across the entire family of ServeRAID M controllers. It allows you to configure, monitor, and maintain drive groups, virtual drives, and advanced features with an intuitive GUI, which reduces administrative efforts and simplifies troubleshooting.
  • 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 that results from theft, loss, or repurposing of drives. Instant secure erase permanently removes data when SEDs are repurposed or decommissioned. 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 ServeRAID 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.
  • MegaRAID flash cache protection
    MegaRAID flash cache protection uses NAND flash memory (which is powered by a 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 by 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 disk.
