Europe Better Equipped for Distributed SANs

European storage managers, like their North American counterparts, have recognized the benefits of storage area networks (SANs), such as lower cost, better availability and utilization, increased performance and scalability. Of 450 users interviewed in 2002 for The Fibre Channel Industry Association (FCIA) Europe, approximately two-thirds had either already consolidated their storage using SAN technology or were planning to. The study predicts a $3.2 billion European SAN market for 2003, growing to $5.7 billion in 2005. But alas, only distributed SANs are really useful, says Aidan Paul, CEO of UK-based Vtesse Networks. "Single-site means all eggs in one basket," requiring third-party provisions for disaster recovery (DR), leading to duplicate data and processing. "Multisite SANs enable self-provided DR," moving the focus from "avoiding discontinuity" to "managing continuity."

    Snapshot and replication are important tools in building a foolproof disaster recovery plan. This article helps you pick the optimal solution that fits within your budget and is best suited for your company's individual backup needs.

  • The case for network smarts

    Let's face it: SANs as they currently exist only deliver about half of what you might hope for in the way of efficiency and optimal utilization. The best bet to deliver the other 50% is network-based storage intelligence. You'll have to get past the magic-wand claims for this latest pancea from storage vendors, though. And not every incarnation of smart switches or appliances is going to be right for you.
