Product Guide (withdrawn product)

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.

Did you know?

The ServeRAID M5225-2GB SAS/SATA Controller is optimized for high-performance, external data

storage, with a 12 Gbps SAS controller that features a 2 GB DDR3 1866 MHz cache memory with flash

backup and PCIe 3.0 host interface.

The ServeRAID M5200 portfolio is designed around several base solutions with upgrades that are rich with

features to satisfy various storage needs while minimizing parts-on-the-floor upgrades.

Upgrade features, such as support for RAID 6 and 60, performance optimization, and caching with solid-

state drives (SSDs) no longer require a hardware key. They are implemented through FoD software

licenses.

Feature Activation Instructions

Features

The ServeRAID M5225-2GB SAS/SATA Controller has the following standard 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

new 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.
