Green shops take MAID for a spin-down

Massive array of idle disks (MAID) has become synonymous with disk spin-down, which has become synonymous with power savings. That's not the way MAID pioneer Copan Systems saw it when it rolled out the first MAID system in 2004. Power savings were merely one benefit, along with increasing the life of low-cost SATA drives by using them less and lowering the cost of disk-based backup and archiving. As green computing has gained in popularity, vendors that followed Copan into the disk spin-down space have made it more about power savings. Hitachi Data Systems calls its spin-down technology Power Savings Storage Service, and offers it for Fibre Channel (FC) as well as SATA drives in its midrange storage arrays. Nexsan Technologies recently made its AutoMAID available on SAS drives. And more is coming: EMC released its first spin-down product this year with plans to offer the technology on all of its disk products, and ONStor is planning to add MAID on its Pantera NAS boxes this year. With other vendors now crowding its turf, Copan's...

  • Get your iSCSI game on: Best Practices

    by  Ashish Nadkarni

    iSCSI is a mature protocol for accessing storage and a solid alternative to Fibre Channel. Technologies such as blade servers and server virtualization benefit from iSCSI as it lets you minimize the number of connections required. And because everything is IP-based, there's no more need to waste slots for host bus adapters, which simplifies your configuration.

  • Backup gets a boost: Hot Spots

    by  Lauren Whitehouse

    Snapshots, continuous data protection and deduplication are making their way into traditional backup products.
