03GX490 Lenovo ThinkSystem RAID 940-8e 4GB Flash PCIe Gen4 12Gb Adapter

Lenovo FRU 03GX490 corresponds to the ThinkSystem RAID 940-8e 4GB Flash PCIe Gen4 12Gb Adapter, which carries option number 4Y37A78836 and feature code BNWJ. The card is an external RAID controller that connects servers to SAS and SATA disk enclosures.

A Broadcom SAS3908 RAID-on-chip controller sits at the core of the adapter, which is based on the MegaRAID 9580-8e. Its PCIe 4.0 x8 host interface is also compatible with a PCIe 3.0 host interface. RAID levels 0, 1, 10, 5, 50, 6 and 60 are standard, and a JBOD drive state is supported.

Eight 12 Gb SAS ports sit on two Mini-SAS HD x4 (SFF-8644) connectors, and up to 240 drives can be attached. The 4GB of cache is protected by flash backup powered from a CacheVault module. Self-encrypting drives are handled through SafeStore, FastPath accelerates SSD volumes, and CacheCade is not supported. Operation is supported from 0°C to 55°C at 5% to 90% non-condensing humidity, and the stripe size is configurable between 64 KB and 1 MB.

Supported external enclosures include the Lenovo Storage D1212, D1224 and D3284 as well as the ThinkSystem D4390 Direct Attached Storage. The earlier ThinkSystem RAID 930-8e adapter, option 7Y37A01087, is an external RAID card on a PCIe 3.0 x8 interface.
