We were never able to achieve storage virtualization in mainstream enterprise IT because we lacked the ability to identify and move data non-disruptively. This has been solved by caching and distributed storage solutions, and it’s only a matter of time before the legacy need for centralized storage falls away.
Everyone is talking about â€œsoftware-definedâ€ everything lately, so it was only a matter of time before industry buzz turned to software-defined storage. VMware and EMC really stoked the flames with a constant barrage of marketing directed in this direction. But how exactly do you software-define storage? And what does this mean?
Scaling storage is a serious challenge for the industry, but there is a great deal of thought, effort, and creativity going into it right now. Companies like Gridstore, Oxygen Cloud, and Cleversafe have come up with effective client-side solutions to enable scale-out storage to sing. If you’ve got an appropriate application, client, or gateway, scale-out is a real possibility!
It is amazing that something as simple-sounding as making an array get bigger can be so complex, yet scaling storage is notoriously difficult. Our storage protocols just werenâ€™t designed with scaling in mind, and they lack the flexibility needed to dynamically address multiple nodes. So my hat is off to these companies and others who have come up with clever ways to maintain compatibility while scaling out beyond the bounds of a single storage array.
It’s time once again for Storage Field Day! As most of my blog readers are aware, I run the Tech Field Day event series, bringing together experts in various IT fields with key companies for a few days of deep technical discussion. This week it’s our fourth event focused on enterprise storage, and it’s going to be big!
I’ll be at NAB Show this year, on Monday and Tuesday, April 16 and 17. That’s literally all I could spare out of my schedule, but I wouldn’t miss it!
This regular series features highlights from the week. Last week focused on Tech Field Day output, with lots of great writeups resulting from our November event. But there’re a few other interesting items included, too!
Single-parity RAID is under attack. Caching is the hottest trend in storage. The end of the high-performance disk drive is imminent. What happened? Increasing areal bit density has caused disk capacity to grow much faster than disk performance. A presentation at Storage Networking World by Ronald Bianchini of Avere exposed the mathematics of this phenomenon.
