There has been a bit of confusion recently over the use of OEM ESXi ISO images and Virtual SAN. These OEM ESXi ISO images allow our partners to pre-package a bunch of their own drivers and software components so that you have them available to you immediately on install. While this can be very beneficial for non-VSAN environments, it is not quite so straight-forward for VSAN deployments. Drivers associated with VSAN have to go through extra testing for some very good reasons that I will allude to shortly. The issue really pertains to the drivers that are shipped with many of these ESXi images; in many cases these are the latest and greatest drivers from the OEM for a given storage controller and may not yet be qualified for VSAN (qualified == tested).
My first introduction to X-IO was via Stephen Foskett’s Tech Field Days. They piqued my interest and I added them to the list of storage vendors that I wanted to check out at VMworld 2014. I started to research these guys a little more, and learnt that they are closely related to Xiotech, a SAN company that I dealt with on occasion when I worked in technical support for VMware back in the day. It seems that Xiotech acquired Seagate’s spun-out Advanced Storage Group in 2007. The guys then began to work on a different product to the Xiotech team, namely the Intelligent Storage Element or ISE array. The Xiotech products were discontinued in 2012 (although the name continues to appear on the VMware SAN/Storage HCL), and the focus was placed on the ISE products. I was a bit confused when I saw that X-IO were not listed on the HCL directly, but after checking with Blair Parkhill, VP of Tech Marketing at X-IO, it seems that they still use their incorporated name, Xiotech.
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
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.
I was in a conversation with one of my pals over at Tintri last week (Fintan), and he observed some strange behaviour when provisioning VMs from a catalog in vCloud Director (vCD). When he disabled Fast Provisioning, he expected that provisioning further VMs from the catalog would still be offloaded via the VAAI-NAS plugin. All the ESXi hosts have the VAAI-NAS plugin from Tintri installed. However, it seems that the provisioning/cloning operation was not being offloaded to the array, and the ESXi hosts resources were being used for the operation instead. Deployments of VMs from the catalogs were taking minutes rather than seconds. What was going on?
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.
