Key points to note on these 81Y4448 IBM ServeRAID cards:-

The ServeRAID M1115 SAS/SATA controller is a part of the IBM ServeRAID M series family that offers a complete server storage solution consisting of RAID controllers, cache/flash modules, energy packs, and software feature upgrades in an ultra-flexible offerings structure.

These ServeRAID M1115 SAS/SATA Controllers are entry-level internal data storage solutions that provide hardware RAID capabilities and advanced features, such as online capacity expansion and RAID-level migration.

The optional RAID 5 upgrade and support for self-encrypting drives no longer require a hardware key, because the upgrade functionality is implemented through Features-on-Demand (FoD) software licenses.

With increased demand for performance and advanced features, the M1115 provides a seamless migration path to the full-featured RAID controllers, such as the ServeRAID M5110. The information about existing arrays can be recognized and imported into the new controller without requiring any reconfiguration.

Additional Features:-

• :: The M1115 offers a low-cost RAID 0/1/10 solution that can be upgraded to a cache less RAID 5 with a features-on-demand license upgrade.
• :: Auto-resume uses non-volatile RAM (NVRAM) to save rebuild progress during a host reboot or power failure to automatically resume from the last checkpoint.
• :: Auto-resume ensures that data integrity is maintained through the process. The card supports a number of features that are able to be implemented without rebooting the server.
