Storage Review, 9/30/15
VMworld 2015 US has come and gone. It was definitely a busy year this year with over 23,000 people in attendance. While the conference starts on Monday morning, Sunday brought the usual community event – VMunderground.
For the last several years, VMunderground has severed as the unofficial start of the conference. It begins with Opening Acts where community experts gather to answers questions and talk about various topics. Opening Acts, for me, made one thing clear – there was going to be a lot of talk about data protection and storage. The fact that a community driven event has a lot of talk about storage set the tone for the rest of the conference. Storage was going to be a hot topic at VMworld 2015.
VMware had quite a few announcements, and since we're talking about storage you know we'll have to talk about VSAN. They made a little more than a dozen improvements for VSAN, but a few of them stand out:
- 2-node cluster support officially announced and I think it is about time. VMware has always touted VSAN as an option for ROBO, but I've always taken issue with this. Even a modest four node VSAN cluster is more than the vast majority of remote offices need.
- They have added support for Intel NVMe devices as part of a VSAN flash tier. This is exciting because it means NVMe is gaining more and more traction, something desperately needed if we hope to push Flash storage to its limits.
- VSAN can now provide persistent storage for containers. This is interesting as it will hopefully allow enterprises to further embrace containers with improved mobility and easier failover.
