Cisco Systems and Hitachi Data Systems will both announce major additions to their storage product lines at this week's Storage Networking World conference in Phoenix.
HDS will reveal that it is using Network Appliance's FAS900 file server engine in front of its Lightning 9900V storage array to create a high-end network-attached storage (NAS) device.
The combined product will be available within the next few weeks, said Phil Townsend, HDS senior director of product marketing.
Michael Peterson, an analyst at Strategic Research, said HDS's position as one of the top suppliers of storage devices for Sans should help it as it enters the high-end NAS sector.
Cisco, meanwhile, is announcing a series of products that use Fibre Channel over IP (FCIP) to transport block-level data via the Internet at Gigabit Ethernet speeds.
FCIP, a tunnelling technology that began to show up in products last year, is most often used to connect remote Sans to a central data center for data backup purposes.
Cisco's FCIP products include an upgrade to its SN 5428 storage switch that will let storage administrators link departmental or workgroup Sans. The company will also announce an eight-port line card that can send data via both FCIP and SCSI over IP for its MDS 9000 series of San directors and switches, plus Fibre Channel port adapters for its 7200 and 7400 series routers.
