Nimble Storage revisited – a chat with Wen Yu

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…

Pure Storage revisited – a chat with Vaughn Stewart

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…

Heads Up! SW iSCSI, hostd and ESXi 5.5 U1 Driver Rollup ISO

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…

A closer look at Bull Storage Solutions

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 list of ESXCLI storage commands you can’t live without

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.

A closer look at Fusion-io ioControl 3.0

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.

A closer look at SolidFire

All Flash Arrays continue to make the news. Whether it is EMC’s XtremIO launch or Violin Memory’s current market woes, there is no doubt that AFAs continue to generate a lot of interest. Those of you interested in flash storage will not need an introduction to SolidFire. These guys were founded by Dave Wright (ex-RackSpace) and have been around since 2009. I have been trying to catch up with SolidFire for sometime as I’d heard their pitch around Quality of Service on a per volume basis and wanted to learn more, especially how it integrated with vSphere features. Recently I…
