ServeRAID M5110 SAS/SATA Controller for IBM System x Express
The ServeRAID M5110 and M5110e SAS/SATA controllers for IBM® System x® are 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 products are optimized to deliver the performance that is demanded by the ever-growing I/O requirements of today's enterprises. While M5110 comes as a small form factor PCIe adapter, M5110e comes integrated with the IBM System x3650 M4 server. They also share a common set of upgrades, simplifying inventory management.
Support for RAID levels 0, 1, 10 standard; support for RAID 5, 50 and 6, 60 with optional upgrades.
This Express option is the same as product number 81Y4481, with an attractive price.
<b>MegaRAID CacheVault flash cache protection</b>
Cache options: 512 MB with battery backup, 512 MB and 1GB flash cache protection.
MegaRAID CacheVault flash cache protection uses NAND flash memory powered by a supercapacitor to protect data stored in the controller cache. This module eliminates the need for a lithium-ion battery 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, CacheVault technology transfers the contents of the DRAM cache to NAND flash (CacheVault flash module (CVFM)) using power from the CacheVault power module (CVPM). After the power is restored to the RAID controller, CacheVault technology transfers the contents of the NAND flash back to the DRAM, which will eventually be flushed to disk.
<b>Some features</b>
