Clustered storage nears critical mass

Clustered storage systems, traditionally used by high-performance computing (HPC) shops that need performance and capacity far beyond typical enterprise requirements, have been gaining traction among enterprises over the last two years thanks to data growth. The advent of Web 2.0 apps and the rise of online service providers over the last year has further blurred the line between HPC compute farms and enterprise IT, and pushed demand for massive, easily scalable storage systems. Until now, startups such as Isilon Systems have been riding this wave, but bigger storage vendors are getting ready to weigh in. Analysts say new products from Hewlett-Packard (HP), IBM and EMC, all slated for 2008 release, will be the catalyst for a major move toward clustered storage in the enterprise over the next year. HP and IBM are both dipping into the clustering market through acquisitions. HP is planning to couple clustered file-system (CFS) software it acquired with PolyServe last February with its own server hardware to create clustered nodes ...

Features in this issue

  • Arrays score with both file and block storage

    Multiprotocol arrays that support block- and file-based storage through a single controller give users the best of both worlds: NAS for file-based information, and Fibre Channel or ISCSI block-based storage for databases and other transactional apps.

  • Case study: NY Mets add deduplication to roster

    With an extensive lineup of corporate data, photos and video, the Mets needed to recruit some backup help. The call went out for low-cost disk backup configuration, including deduplication and compression to reduce the amount of data to be backed up, as well as WAN optimization/acceleration to speed up the replication process. After much consideration, Data Domain was drafted for the job.

  • Ask the Expert:RAID rebuilds

    I run four 400GB SATA drives configured with RAID 5. I want to replace them with four 750GB drives. Can I rebuild and then swap individual drives?
