IBM said it has added asynchronous data replication to its deduplication appliance, which allows remote back up and restore between ProtecTIER boxes.
The native replication feature will be available Sept. 4 as an optional feature on new ProtecTIER orders and as a software upgrade for existing TS7650G ProtecTIER Deduplication Gateway boxes and TS7650 ProtecTIER Deduplication VTL Appliances.
ProtectTIER, which IBM obtained when it purchased Diligent Technologies Corp. a year ago, can be used as either a virtual tape library (VTL) for backing up data to disk before it is offloaded to tape archival systems or as a gateway between servers and primary storage arrays to reduce storage capacity requirements by removing duplicate data.
“In the past, using replication to protect data has been reserved for only the most mission critical applications because of the cost of network bandwidth required to enable replication,” said Cindy Grossman, vice-president of tape and archive storage at IBM. “By combining the powerful data reduction capabilities of ProtecTIER deduplication with native replication technology, that level of protection can now be extended to a much larger range of applications, which means customers no longer need to make trade-off decisions on enabling replication for only a few key applications.”
While not unique – Data Domain, Sepaton and FalconStor are among the many companies offering data deduplication appliances and VTLs – Diligent’s ProtectTIER was the first deduplication VTL on the market when it was released in 2005.
The list price for the replication feature is approximately US$2,000 per terabyte of data on the appliance, according to IBM.
