Clogged Device Drain? Use Your Data Snake!

Lee

By Lee LaFresePlunger

Have you ever run into high I/O response times that simply defy explanation? You can’t find anything wrong with your storage to explain why performance is degraded. It could be a classic “slow drain device” condition. Unfortunately, you can’t just call the data plumbers to clean it out! What is a storage handyman to do?

Compressing Wisely with IBM Spectrum Virtualize

Brett

By Brett Allison

 

Compressing Wisely - CompressionCompression of data in an IBM SVC Spectrum Virtualize environment may be a good way to gain back capacity, but there can be hidden performance problems if compressible workloads are not first identified. Visualizing these workloads is key to determining when and where to successfully use compression. In this blog, we help you with identifying the right workloads so that you can achieve capacity savings in your IBM Spectrum Virtualize environments without compromising performance.

Today, all vendors have compression capabilities built into their hardware. The advantage of compression is that you need less real capacity to service the needs of your users. Compression reduces your managed capacity, directly reducing your storage costs.
