Doing DR the VMware way

AT FIRST GLANCE, server virtualization technology is a way to consolidate physical servers and improve utilization. Beyond that, server virtualization is also emerging as an elegant alternative to traditional disaster recovery (DR) methods. Comarco, an Irvine, CA-based electronics manufacturer, undertook a project last year to protect against a catastrophe that would take out its Exchange, SQL Server and file servers. Sean Anderson, the firm's IT manager, initially looked at hosting four hot servers at a nearby SunGard facility, but the asking price for that setup was approximately $10,000 per month. Instead, Anderson cobbled together a DR solution out of a Hewlett-Packard (HP) server, VMware server virtualization software and Double-Take replication software--all for about $60,000 in capital costs plus $600/month in bandwidth charges. The HP server resides in Anderson's office in Spokane, WA, and is running four virtual machines, one for each server replicated in Irvine. Replication is a few seconds behind the main site, but ...

Features in this issue

  • Deduplication extends to archives

  • Lock up data with fixed-content storage

    For most companies, fixed-content storage requirements are simple: Store the data securely, do it cheaply and provide fast access. With more data subject to external and internal audits, content-addressed storage products are becoming the preferred storage medium for long-term protection of fixed content.

  • Storage growth drives buying plans

    The results from our exclusive semi-annual Purchasing Intentions Survey are in. Storage growth is a key concern for storage managers, as additional capacity has a ripple effect that touches many other components in the storage environment.

  • Is encryption enough?

    Encrypting data at rest is definitely a reliable security measure, but it should be considered only one component of an effective storage security plan.

  • Time to think outside the box when it comes to data protection

    Storage Bin: The concept of "That's the way we've always done it" isn't going to work anymore, and it sure won't help you build an efficient disaster recovery plan. It's time to think outside the box when it comes to data protection.

  • The rise of the ultra-dense array

    by  Stephen Foskett

    Disk drives are getting smaller and smaller even as their capacities rise. Now storage vendors are packing more disks than ever into smaller spaces, which saves costly data center real estate. But the denser arrays also have a downside--higher power consumption and more heat.

  • A look at data classification products for e-discovery

    New technology products that look inside data can help you classify and manage that data more effectively. But these tools can also be leveraged for e-discovery, allowing specific data to be found and acted upon quickly to satisfy legal requirements.
