Hitachi Data Systems Inc. (HDS) announced it will resell three software products from Diligent Technologies Corp. that will allow it to offer its own rebranded line of virtual tape librarieis (VTL) for the mainframe and open systems. The products are called VTF Mainframe, VTF Open and ProtecTier VT for Open Systems.
ProtecTier VT, another Diligent product offered as an option on HDS' open systems VTL, is a dedupe engine that does bit-by-bit comparisons of already stored data for single instancing purposes, rather than using a hashing algorithm that assigns an identification number to certain pieces of data and matches those numbers for deduplication.
According to Victor Nemechek, product manager for VTL at HDS, this aspect of the product means there is less of a chance of data corruption. "We can guarantee 100% data integrity," Nemechek claimed.
However, the dedupe method means a performance hit -- the VTL's native performance per server, according to Nemechek, is 480 MBps, and ProtecTier cuts that to 250 MBps.
"There is a performance hit there, but there is also the benefit of storing a larger amount of data on a smaller amount of physical disk," he said.
HDS is claiming a "middle of the road" compression ratio of 25 to 1, and that some customers are seeing up to 60 to 1 compression depending on the type of data.
"But for customers who value throughput more, that's

The VTF product, which consists of a Linux server running the Diligent software and attached to HDS storage arrays on the back end, can scale three different ways -- users can add front-end ports to the Linux box, the better to attach more servers; more back-end ports, the better to attach more storage; or more servers for clustered performance.
"At over 400 MBps native throughput, clustering four VTF servers would give you 1.7 terabytes per hour throughput," Nemechek said.
Pricing for the VTF mainframe is based on millions of service units and starts at $8,000. Open Systems pricing is based on the number of host bus adapters of the VTL server and starts at $25,000. ProtecTier pricing starts at $40,000.
HP, McData on the rocks? A note issued by RBC Capital Markets Corp. analyst Thomas Curlin recently said that "sources indicate HP [Hewlett-Packard Co.] is discontinuing the sale of its McData Corp.-sourced switching products."
The report continued, "Sources have pointed to a stronger presence from both Brocade [Communications Systems Inc.] and Cisco [Systems Inc.] at the expense of McData. Brocade in particular appears to have re-engaged the channel in an effort to build out its branded business and emerging market offerings."
HP has declined to comment publicly on the status of its relationship with McData, but McData officials have said that the reseller relationship with HP remains alive and well.
