Data center, IT, and general consumer server environments have a broad range of requirements-from basic connectivity to extreme data storage capacities. The Series 8E 12 Gbps PCIe Gen3 SAS/SATA RAID adapters deliver the robustness of hardware RAID in an entry-level solution. They offer significant performance acceleration over other 6Gbps adapter card solutions through basic RAID 0,1,10 and built-in cache for cost-effective platforms that dont require the full performance and capabilities of our standard Series 8 RAID adapters. The 8805E, with eight internal SAS/SATA ports, is ideal for applications that require more bandwidth. Both models fit the requirements of industrial PC workstations or entry-level servers. The 8405E and the 8805E support a maximum of four and eight devices respectively, as neither support the use of expanders. Manufacturer: Microsemi Corporation. Manufacturer Part Number: 2293901-R.
