Best Practices: Pull the plug on high energy costs

Storage systems account for a big chunk of the data center electric bill. Here are some ways to reduce your costs. There's been a flurry of activity among IT vendors to develop energy-efficient storage products and with good reason--the cost of electricity continues to rise in every part of the country. Energy experts' opinions differ on the size of the rate hikes, but one thing remains clear: None of the experts expects the rates to remain the same or decrease. Some even foresee a dire future in which the total cost of powering and cooling a server for four years exceeds what it cost to acquire the server. For some data centers located in metropolitan areas, it's not just the spiraling cost of electrical power that's a concern; availability may be an even greater problem. They simply can't pull any more power off the existing electrical grid. To bring in new hardware, they have to unplug older hardware first, making the migration effort to updated hardware difficult and risky. Cutting the cost of energy Companies concerned ...

  • How SANs aid backup

    by  Bradley Hughey

    The primary motivation for building a SAN is often to meet a pressing need for performance, scalability or both. But today's new SAN buyers are looking for more than performance and scalability; they're interested in better ways of protecting their data, using such techniques as snapshots of SAN volumes and sometimes even relying on newer technologies to replace traditional backups.

  • Protect Exchange data

    by  Jerome Wendt

    Email is now firmly established as a critical application, with more than 60% of enterprises using Microsoft Exchange for their corporate email, according to Gartner. This widespread adoption of Microsoft Exchange, and growing electronic discovery requirements, make protecting it a more complicated proposition than just performing simple backups and recoveries.

  • New role for tape libraries

    by  Jerome Wendt

    Tape libraries are finally assuming the role they were designed for: longterm protection and preservation of data. But as disk assumes its new role as the initial target for backups and the source for restores, tape library vendors need to shore up their abilities to interact with disk libraries and provide users with some definitive answers on encryption.

  • Storage Bin: Who ate the backup?

    It's astounding that in this age of technological advancements we still talk about things like backup, let alone agonize over it.

  • Best Practices: Sorting out remote-office backup

    Remote-office data has always been something of a corporate orphan when it came to backup. Once upon a time, "out of sight, out of mind" might have worked, but times have changed. Regulatory compliance, legal liability issues and the cost of producing data for ediscovery make it clear remote data can no longer be ignored.

  • Best Practices: Pull the plug on high energy costs

    by  Dianne McAdam

    Spiraling energy costs are taking an increasingly big chunk of the data center budget. Data centers are grappling with rising electrical bills and, in some locations, limitations on the amount of available power are forcing IT anagers to rethink their basic processes.

  • Hot Spots: Managing storage in a virtual server world

    Server virtualization is the big data center story, and storage managers need to design their storage systems to take advantage of a virtualized server environment. There are steps you can take now to ensure that your storage systems are up to the task.
