Special Price $982.50 Regular Price $1,029.28
Quick Overview
ThinkSystem RAID 940-8i 4GB Flash PCIe Gen4 12Gb Adapter
- PCIe 40 x8 host interface also compatible with a PCIe 30 host interface
- 12 Gbps SAS/SATA RAID controllers based on the Broadcom MegaRAID 9560 adapter family
- 4GB or 8GB of integrated flash-backed cache
- RAID 940-8i supports up to eight internal SAS or SATA drives
The RAID 940 Series adapters all have a PCIe 40 host interface which doubles the bandwidth between the server and the adapter compared to the previous generation RAID 930 adapters This improves overall performance of the storage subsystem by supporting up to 3 million IOPS (JBOD mode) and up to 3 million IOPS in RAID (random reads)
RAID on Chip-based controllers such as the RAID 940 adapters have a dedicated processor that offloads all RAID functions from the servers CPU With hardware acceleration for RAID 5 and 6 operations plus up to 8 GB dedicated memory for caching the 940-8i 16i and 32i offer the ultimate performance for ThinkSystem servers
