solid state drives
While there was a “flash” of NetApp’s solid state strategy evident in its product launch this week, a big part of it was missing in all the talk of Data Ontap 8 and the vendor’s cloud strategy. The missing part was support for solid state drives (SSD) in NetApp disk arrays. NetApp chief marketing officer Jay Kidd says that’s coming by the end of 2009.
But SSDs in the array are part three of NetApp’s three-part flash strategy. The first part was DRAM-based Performance Acceleration Module (PAM) cards that shipped in February. Now NetApp is rolling out PAM II, which delivers flash memory as cache. The difference in the two PAM cards is the first one has about 10 times faster access times than flash, but costs about 10 times as much. The new flash-based card provide more capacity – the cards come in 256 GB and 512 GB configurations and you can use multiple cards to get up to 4 TB in one system.
“Customers found adding more DRAM cache memory accelerated performance of their workloads, but we had requests for larger capacities,” Kidd said.
Step three will be support for SSDs in arrays, which every other major storage vendor now offers. “We’ll have certification of SSD drives in disk shelves later this year,” Kidd said. “You’ll be able to add them to existing systems, probably with additional disk shelves that support SSD.”
Kidd says NetApp will use SSD drives with native SAS interfaces.
