As many of you are aware, I was at VMworld in San Francisco last week. I wrote a number of articles about some VMware storage announcements, such as EVO:RAIL, VAIO and VVols. However there were, as usual, quite a number of storage vendors at this years conference. One of the vendors that I really want to learn more about was Kaminario, an all flash array vendor that I’d heard a lot of things about. I had the pleasure of spending some time at the Kaminario booth with Shai Maskit who is a senior Product Manager with Kaminario. I posed my usual set of questions to learn a bit more about their AFA products. Continue reading
Yesterday was my first day at VMworld 2014. As usual with this event, there are simply so many interesting announcements that it is hard to keep track. However, for me, there were a few things which stood out in the storage space worth calling out. These are specifically VMware focused products and features. I know that many of our partners have also made announcements in the storage space, but for today I concentrated solely on VMware. There are the two that really caught my attention.
Last year I published a list of storage vendors and partners that I was planning to check out at VMworld 2013. This year is no different, with a number of new arrivals on the storage scene, as well as some super new cool products from many of VMware’s partners. Whilst this is no means a definitive list of what’s on show, these are the ones that I am particularly interested in checking out this year.
On a recent trip to VMware in Palo Alto, I found some time to visit with a good pal of mine, Vinay Gaonkar, who is now the Product Manager for XtremIO over at EMC. Vinay used to be a storage PM at VMware (he worked on the initial phases of VVols), and we worked together on a number of storage items in various vSphere releases. It’s been almost 2 years since I last spoke to the XtremIO folks (VMworld 2012 in fact, when the product still had not become generally available), so I thought that this would be a good time to catch up with them, as we are in the run up to VMworld 2014.
Although I didn’t attend EMC World this year, there were a lot of interesting announcements. I managed to catch up with Matt Cowger (who sorts of sits between both the EMC & VMware camps) and ran through some of the main highlights from this year’s conference. There has been a lot written about EMC World already (and I mean a lot) so I’m going to try to keep the highlights to a minimum, and provide links to where you can read more.
In this post, we talk about a particular behaviour with using the default (or None) policy with VSAN. I have stated many times in the past that when a VM is deployed on the VSAN datastore, it behaves like it is thinly provisioned unless the capability ‘Object Space Reservation’ (OSR) is specified in the VM Storage Policy. The OSR will pre-allocate space on the VSAN datastore for the virtual machine’s storage objects, and is specified as a percentage of the actual VMDK size. However, there is a slightly different behaviour when the default policy is used. Once again, I was in a conversation with a customer who stated that when he used the default policy of “None”, he could see space being consumed on the VSAN datastore was equal to the size of the VMDK * FTT (Number of Failures To Tolerate). He wondered why this was the case when the default policy clearly did not contain an Object Space Reservation capability.
Nimble Storage are another company who have been making a lot of waves in the world of storage in recent years. Based in San Jose, CA, they IPO’ed earlier this year, and have something in the region of 600 employees worldwide at the present. I caught up with Wen Yu, who I have known from my early days at VMware where we worked together in the support organization. Wen moved over to Nimble a couple of years back and now is a technical evangelist at Nimble. Actually, Nimble were the subject of the very first post on this blog site when I launched it almost 2 years ago. At the time I wrote about some significant architectural updates in their 2.0 release. My understanding is that their next major release (2.1) is just around the corner. So this was a good time to chat with Wen about some new features and other things happening in the Nimble world.
