For Monster, managing this challenge required multiple tools, a situation that's not uncommon. Monster uses Akorri's BalancePoint to augment the capabilities of VMware's two main management products, VMotion (which increases hardware utilization by migrating VMs on failing or underperforming servers to another machine) and Distributed Resource Scheduler (which couples with VMotion to allocate resources to high-priority VMs based on preestablished rules you set).
A key point: DRS and VMotion show where to balance workload, but they aren't analytical and don't see contention with other apps outside of VMware, King says. Since BalancePoint isn't tied to the OS, it can see if VMware performance is impacted by other apps residing on the same SAN resources, he says. "DRS just sees what it sees for performance through the host (CPU, memory and storage), but it can't see what the database server that's on the same side as the SAN is doing," says King.
Using BalancePoint from Akkori helped them manage the evergrowing farm of the VMs. Remember that it will happen to you too. Do make sure you go ahead with the right partner when managing your Virtual Infrastructure.
