For anyone unfamiliar with Nytro MegaRAID PCI Express cards, they are PCI Express boards that bring together multiple storage units into RAID setups.
Basically, they are an alternative to SSD-only arrays or over-provisioned direct attached HDD environments, a cheaper one.
Since cache memory matters a lot in the performance of such arrays, Intel and LSI worked together to build Nytro MegaRAID PCIe cards with 512 GB cache and even 1 TB cache, all supplied by SLC NAND Flash chips.
Seeing as how even a 100 GB SLC card needs a payment of $1,795, we can only wonder how much the 1 TB beast will cost.
RCS25ZB040LX is the Intel cache controller that actually manages the 1 TB flash storage. It can configure up to 128 devices in RAID 0, 1 ,5, 6, 10, 50 or 60.
