A first look at Cohesity

cohesityI mentioned in an earlier post that Cohesity were one of the vendors that I wanted to check out at VMworld 2015. These guys have only literally exited stealth. Just yesterday, I sat in on a webinar from Nick Howell, who I know extremely well from his days in technical marketing over at NetApp. Nick has now joined Cohesity as the role of an evangelist, which I think is a great move on Cohesity’s part. On Nick’s webinar, he introduced us to the vision behind Cohesity’s product, what they hope to fix in a customer’s environment and some teasers regarding where the direction “may” be going in the future.

A first look at ClearSky Data

clearskyI had a heads-up recently on a new company, ClearSky Data, who only exited stealth today. I want to make it clear that I have not yet been briefed by the folks from ClearSky, but I am definitely hoping to chat with them at VMworld 2015 (they’ll be at booth 441). Therefore a lot of what I have in this post is conjecture on my behalf. It seems to me that their goal is to help change how enterprise IT teams buy, manage and optimize their storage. Instead of consuming traditional storage arrays (alongside backup and disaster recovery (DR) infrastructure) in data centers, they want customers to reconsider another approach with ClearSky. However they do realize that while the current storage clouds offer great scalability and economics for archives and infrequently used data, they’re not so good for primary storage workloads. So how can this be addressed?

vROps Management Pack for Storage Devices 6.0.2 is GA

Today sees the release of the vRealize Operations Management Pack for Storage Devices (MPSD) version 6.0.2. This is exciting for me as it means that vROps now has management and monitoring features for Virtual SAN 6.0.  The management pack comes with a set of default dashboards for Virtual SAN clusters, as well as the ability to monitor and create proactive alerts/notifications based on VSAN events.

I took the vROps Management Pack for a spin a little while back, and used it on my own lab cluster. Included below are a few of the features that it has.

Handling VSAN trace files when ESXi boots from a flash device

I’ve been involved in a few conversations recently regarding how VSAN trace files are handled when the ESXi host that is participating in a VSAN cluster boots from a flash device. I already did a post about some of these considerations in the past, but focused mostly on USB/SD. However SATADOM was not included in this discussion, as we did not initially support SATADOM in VSAN 5.5, and only announced SATADOM support for VSAN 6.0. It seems that there are some different behaviors that need to be taken into account between the various flash boot devices, which is why I decided to write this post.

New storage vendors to check out at #VMworld 2015 (SFO)

vmworld2015As usual, there have been loads of things happening over the last 12 months in the storage space. The Solutions Exchange at VMworld is always a great place to meet new storage startups, and get some further information on their respective products and innovations. This year, I’ve made a note of a few startups that I wish to catch up with at VMworld 2015 and find out what issues are they trying to address with their technology, and why should a customer choose  their solution over some of the others in the storage space.

Disclaimer: Please note that I am not endorsing any of these vendors. This is simply technology that I am interested in, and something I want to learn more about at VMworld. I’d urge any readers attending VMworld to do the same. For those not attending, my goal is to learn enough about these new startups so that I can write an article about them at some point (if I haven’t already done so).

Is VSAN for you? It’s never been easier to check…

captain-vsanA common question we receive when we meet with customers and talk about Virtual SAN is “whether or not VSAN is going to be able to run my particular workloads?” This is a great question to ask, as most customers are coming from a background of SAN or NAS storage arrays, fibre channel, FC switches, HBAs, CNAs, etc. Since VSAN is still relative new (18 months old at this point), being confident that this new product can successfully run existing virtual machines and applications is paramount. To that end, VMware has developed a number of tools that are simple to use and will provide customers with all relevant details on their current workloads, and whether or not these workloads will run on VSAN.
