Data Protection For Tight Spaces
MegaRAID SAS 8704EM2
The MegaRAID SAS 8704EM2, a second-generation SAS/SATA RAID product from LSI, provides high-performance and cost-effective data protection for systems using SATA or SAS hard drives. Built with a x8 PCI Express host interface, 667-MHz DDRII memory, and the LSI SAS1078 ROC controller, the MegaRAID SAS 8704EM2 is a powerful RAID solution for traditional application servers employing four direct-connect drives or up to 32 drives using SAS expanders. With a true MD2 low-profile form factor, this adapter is ideal for today's data centers where space is at a premium.
The MegaRAID SAS 8704EM2 supports all key RAID levels including RAID 6 and 60 for increased fault tolerance. RAID 6 tolerates two simultaneous drive failures, and thus the ability to manage unrecoverable media errors during rebuilds, which is useful for those using many high-capacity SATA disk drives.
