EMC and HP Spin Disk: Page 3 of 4

“We’re not positioning this as cheaper than tape,” Hollis says. “Tape is pretty cheap stuff. I don’t think it will ever be cheaper than tape. Disk libraries are more expensive, but they do more.” EMC’s disk library will be available next week.

HP’s drives provide a Fibre Channel connection to ATA drives -- in effect, an option to high-cost Fibre Channel drives and low-cost Serial ATA (SATA). HP says the drives will cost about half as much as traditional Fibre Channel drives and not much more than SATA because the FATA drive slides into HP’s Enterprise Virtual Array (EVA) SAN systems. Customers don’t have to buy a new shelf, as they would to install SATA drives.

If used with a dual-port 2-Gbit/s Fibre Channel interface, FATA drives can hold 250 Gbytes of storage. HP expects to make the new drives available in July.

You have to wonder if HP’s not too late with the new drive technology. Do customers really want another disk option?

HP says the FATA drives are meant for SANs where bulk storage and lower price per gigabyte are more important than access time. But that’s the same market SATA is aimed at -- and SATA offers more than just reduced disk prices. SATA drives and the emerging iSCSI interface are part of the IP SAN structure that many see as long-term alternative to Fibre Channel. So why would they embrace a new Fibre Channel technology?
