Today`s newest external enclosure designs are based on architectures that support both SATA and SAS hard drives. The MegaRAID SAS 8880EM2, with eight external SAS/SATA ports, is the ideal solution for configuring these external enclosures with either high-performance SAS drives or high-capacity SATA drives. This second-generation MegaRAID adapter features an LSISAS1078 storage processor, the fastest DDRII memory available today, and a x8 PCI Express host interface to provide the ultimate performance for external applications. Since system builders can use the MegaRAID SAS 8880EM2 to support one enclosure design that can be populated with either SAS or SATA hard drives, they can ultimately reduce the total cost of ownership, maximize the overall value of the investment, and reduce the number of supported skus.
