Taneja Group on ProtecTIER's IP Native Replication

  1. 1. S O L U T I O N P R O F I L E IBM ProtecTIER Adds Native Replication December 2009 Ever since their acquisition of Diligent in 2008, IBM has been a top player in the enterprise-level deduplication market. The ProtecTIER deduplication product line, which includes both easy-to-deploy appliances and highly scalable gateway options, proved to be a good acquisition for both companies and allowed IBM to supplement theirstrong tape backup business.However, we were initially concerned about a lack of native replication in ProtecTIER.Diligent had not added the feature and IBM did not immediately provide it post-acquisition. The main reason for the delay was that in enterprise accounts, whereProtecTIER’s high performance and petabyte scalability played very well, customersalready practiced array-based replication and had little interest in using another methodof replication for ProtecTIER. But as IBM moved down-market, they found that mid-market customers rarely used array-based replication, citing expense and complexity.To serve this market – and any enterprise customers who wanted it -- IBM added nativereplication capabilities to the ProtecTIER product family.This Product Profile will detail where ProtecTIER is today, how native replicationincreases its value to enterprise and mid-market customers, and how customers areusing ProtecTIER to protect their critical data.Challenge solution.
