News on Blade Storage

Arthur Cole

Blades are having an impact on the data center in more ways than one. The tighter, denser servers draw more power for both processing and cooling operations, which is a serious concern in itself. But each blade also requires someplace to store data, which adds to the burden of the data center, in terms of power, space and capital expenditures.


So it's refreshing to see a number of new storage blade architectures hit the market, which should hopefully bring processing and storage requirements more in line. QLogic's new SANbox 9000, for one, offers up to eight 10 Gbps switch blades, plus a Storage Service Platform (SSP) blade designed for volume management, replication and other functions.


EMC is also adding its blade system to the Celerra line of NAS devices, along with the CLARiiON CX3 UltraScale architecture.


Also, there are a number of new blades with on-board storage. HP is said to be working on a new storage blade system with up to six 146 GB disks, offering more than 1.1 TB of storage in a half-frame rack.
