High-availability solutions in nonvirtualized environments
This article is part of the March 2009, Vol. 8 issue of Virtual Data Center
Time is money. It's an old axiom that's still true for today's enterprises. For data-intensive businesses, the cost of downtime can easily exceed six figures for each hour of lost network access or user productivity. Data centers have long relied on high-availability solutions for the redundancy needed to circumvent operating system snafus, server faults and other infrastructure problems. Now server virtualization has raised the stakes, allowing numerous virtual machines (VMs) to operate in isolated instances on the same physical server. More on high-availability solutions How to offer high-availability solutions with SQL Server 2008 Distributed computing, clusters and high-availability solutions How much will you pay for mission-critical IT? Although virtualization supports enormous consolidation in data centers, it also increases the risk for organizations. Companies that deploy server virtualization need to re-assess their high availability (HA) approach, drawing on traditional network architecture while exploiting the ...

Features in this issue
High-availability solutions ensure uptime and help avoid infrastructure problems. But without virtualization, their hardware and software requirements can be quite pricey.
Evaluate failover capabilities, service-level requirements and shared storage before choosing high-availability software to create a high-availability architecture.
Terminal services offerings reduce memory and storage requirements and allow far more users to share an application at the same time.
