High-Performance RAID for 1U/2U

Application Servers

The MegaRAID SAS 8704EM2, a second generation SAS/SATA RAID product from LSI, provides high-performance and cost-eff ective data protection for systems using SATA or SAS hard drives. Architected with a x8 PCI Express host interface, 667MHz 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-profi le form factor, this adapter is ideal for today’s data centers where space is at a premium.

RAID 6 for Advanced Data Protection

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 re-builds. This is particularly useful when using a lot of high-capacity SATA disk drives.

Intuitive RAID Management Utility

The MegaRAID Management Suite™ provides age MegaRAID products, whether deployed in an enterprise or small business. LSI off ers a collection of applications and tools including a pre-boot setup utility and a full spectrum of online RAID management utilities. This new suite of applications allow administrators to adjust SAS topology views from the system host, controller and disk enclosure down to the logical and physical drive level. Extending to enterprise deployments, these tools scale to easily confi gure, monitor and manage RAID volumes locally or over the LAN network.

Intelligent Battery Backup Support

The MegaRAID LSIiBBU06 is a battery-backup module that protects the integrity of the cached data on a MegaRAID controller in the event of a complete power or server failure. This add-on module, which connects directly to the adapter, has the added functionality to automatically charge the battery pack and communicate with the host system the battery status, such as voltage, temperature, and capacity.
