What do you do when a virtual machine becomes a noisy neighbor?

Virtualized application performanceThe #1 pain point in the data center is poor performance. That’s what we found from our study of 1,000 data center professionals, who every day watch virtual machines (VM) conflict with databases, slow each other down, and eat up hours spent fine-tuning storage and tackling trouble tickets.

A huge contributor to this performance pain is what’s called “the noisy neighbor problem” — a VM consuming too many resources at the expense of others.

The problem stems from LUNs, the conventional storage groups made up of dozens or even hundreds of VMs. When one of them gets noisy, demanding more than its share of performance reserves, it slows down its neighbors and throws the entire LUN into chaos.

Because they’re built on that LUN architecture, most storage environments running VMs face this challenge. Stopping these rogue VMs is difficult because they’re nearly invisible to scrutiny and correction.

Here’s how you put the issue to rest and guarantee every VM’s performance: isolation. By eliminating the LUN and giving every VM its own neighborhood through VM-aware storage, you can more precisely control the resources apps can demand. Continue Reading…
