“IBM (NYSE: IBM) today unveiled its entry in the growing market
for clustered network-attached storage (NAS) systems.

“IBM said its new Scale Out Network Attached Storage (SONAS)
offering can scale both capacity and performance while providing
parallel access to data and a global name space that can manage
billions of files and up to 14.4 petabytes of capacity.

“The new offering is a hardware-based expansion of Big Blue’s
Scale Out File Services and is based on IBM’s General Parallel File
System (GPFS).

“The Samba-based systems include management nodes, switches,
interface nodes, data storage nodes, RAID controllers and expansion
units, and offer snapshot capabilities, tiered storage and HSM
through Tivoli Storage Manager (TSM).

“It includes Gigabit Ethernet, 10Gigabit Ethernet and 20Gbps
InfiniBand connections, and the storage system can combine up to 30
interface nodes and 30 240-drive storage pods to reach 7.2PB with
1TB drives and 14.4PB with 2TB drives, which will be coming in
April, a month after general availability.”
