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.
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.
Pure Storage are all over the news at the moment. They just secured another round of funding (225 million to be precise), and are now valued at over 3 billion. You can read more about that here. However, even before this announcement, I had already arranged to have a catch up chat with Pure’s primary evangelist (and a good pal of mine), Vaughn Stewart. I was surprised to see that it had been 18 months since I last did a piece on Pure so I really did want to see what changes they had made in the meantime as there were a few vSphere interoperability pieces still to be completed when we last spoke.
My good pal Duco Jaspars pinged me earlier this week about an issue that was getting a lot of discussion in the VMware community. Duco also pointed me to a blog post by Andreas Peetz where he described the issue in detail here.
The symptom is that the ESXi hostd process becomes unresponsive when software iSCSI is enabled. There is another symptom where an ESXi boot hangs after message “iscsi_vmk loaded successfully” or “vmkibft loaded successfully”. This has only been only observed with the ESXi 5.5 U1 Driver Rollup ISO. It has not been reported by customers using the standard ESXi 5.5U1 media. The VMware ESXi 5.5 Update 1 Driver Rollup provides an installable ESXi ISO image that includes drivers for various products produced by VMware partners.
Initially it was reported in the community that it appeared to be an issue with the Diablo TeraDimm driver that was shipped as part of the roll-up. However further investigation has concluded that the Emulex
be2iscsi driver is at fault and is the root cause. VMware support are recommending that you use an updated be2iscsi driver as per KB article 2075171 to address the issue.
I thought it was about time that I looked at some of the larger storage vendors closer to home. One of these is of course Bull. This company is probably more familiar to those of us based in Europe rather than those of you based in the Americas or Asia Pacific. However VMware customers in EMEA will have seen them in the Solutions Exchange at VMworld Europe, where they have a reasonably large presence. After some conversation with my good pal Didier Pironet, whom I’ve met at a couple of recent VMUGs, I was introduced to Philippe Reynier who is a manager in the Bull StorWay Competence Center and Solution Center. Philippe provided me with a lot of good detail on Bull’s storage solutions which I will share with you here.
There are many occasions where the information displayed in the vSphere client is not sufficient to display all relevant information about a particular storage device, or indeed to troubleshoot problems related to a storage device. The purpose of this post is to explain some of the most often used ESXCLI commands that I use when trying to determine storage device information, and to troubleshoot a particular device.
Last week I had the opportunity to catch up with Mike Koponen and Dean Steadman of Fusion-io. I had met with Mike and Dean at VMworld 2013, and spoke to them about the Fusion-io acquisition of NexGen storage earlier last year, and what plans Fusion-io had for this acquisition. Well, the result is ioControl Hybrid Storage, and we discussed some of the architecture of ioControl as well as a number of vSphere integration points.
