10 ways to improve virtual server storage
This article is part of the Storage magazine issue of May 2013 Vol. 12 No. 3
Virtual server storage operations can have a profound effect on the storage network. Here are 10 ways to help ensure that your storage yields its best I/O for the VMs it supports. Enterprise virtual infrastructure will always use shared storage. It's a fact of life -- if you want to use the advanced features of VMware vSphere and Microsoft Hyper-V, all your hosts will need access to the files that make up your virtual machines (VMs). While the latest editions of VMware VMotion and Microsoft Live Migration don't require shared storage, most features like VMware vSphere High Availability and Microsoft Failover Clustering still do (and likely always will). For the virtual infrastructure (and your critical applications) to perform well, they must be fed the virtual CPU, virtual memory and virtual disk I/O they hunger for. The monitoring of virtual CPU and memory has gotten easier as hypervisors have made more statistics available and monitoring tools have gotten smarter. However, performance monitoring for virtual infrastructure ...

Many storage shops are fighting a losing battle when it comes to data storage and backup protection, with too much data and not enough time. Maybe it's time to rethink the process.
Storage virtualization and other storage "uber-controllers" are a step toward better storage infrastructure management, but it's still not an integrated process.
Object technology has received a lot of attention lately, so there should be plenty of use cases for it. But object storage might be the answer to a problem not yet discovered.
NAND flash-based storage is becoming a common alternative, but NAND flash could soon be replaced by newer forms of non-volatile memory like MRAM technology.
