According to Tintri, the rise of server virtualization broke the traditional storage system. Initially we had relatively simple environments where one server talks to a number of LUNs on a storage system. Sometimes we’d have a small cluster of servers accessing those volumes. Still relatively simple.
Fast forward to now: large clusters of hypervisor hosts are the norm, collectively accessing an even larger number of volumes. Each hypervisor in turn hosts a large number or virtual machines. In case of performance problems, how are you ever going to figure out the root cause and which other systems are affected?

Earlier this year Nimble Storage announced their all-flash array called the Predictive Flash Platform; you can read my thoughts on the launch over here. InfoSight is one of the core components of that announcement, which is why we had the opportunity for a fireside chat with the Nimble Storage data science team. We discussed the workings of InfoSight & VMVision and how this relates to actual benefits for an owner of a Nimble Storage array. This post will also touch on some of the key points discussed during the later Storage Field Day 10.

A couple of weeks ago StorMagic announced their newest SvSAN 6 release. The basics are still the same: SvSAN takes the internal disks from two hypervisor servers (HyperV or VMware) and turns them into highly available shared storage. Yes, that’s a two server minimum, not three; so this should be a little bit cheaper compared to VMware VSAN and the likes. What’s new in version 6 is the addition of an Advanced edition with SSD and memory-based caching and tiering.

Question: What do you get when Pure Storage gets to build a system that can start small, grow big, handle file requests quickly and is simple to manage?
FlashBlade: Pure’s newest addition to its hardware portfolio. The Pure Storage FlashBlade is not just another NAS filer. It’s an all-flash, scale-out storage for file (NFSv3 for now) and object (soon), delivering some pretty good performance as you can see in the sheet above. And the chassis just looks sexy…

If you want to build a private S3 object store, Cloudian HyperStore might be the product for you. Using commodity servers to form a scale-out architecture, you can build your own, fully S3 compliant object storage that’s located in your own datacenter. If you don’t want to supply your own servers, you can opt for the Lenovo Storage DX8200C appliance, powered by Cloudian!

Kaminario presented about there all-flash array back at Storage Field Day 7. Back then, I have to admit I wasn’t too impressed: it felt like just another all-flash array with few differentiating factors. For me, that changed after their presentation at Storage Field Day 10. The two components they’ll be adding are a policy based QoS system and a cloud based monitoring system called Healthshield. Both should help simplify storage management and look beyond merely the storage array itself. But first, a quick recap on Kaminario: who are they and what do they do?

In a couple of hours I’ll be airborne again heading west towards Silicon Valley. This time it’s for Storage Field Day 10 or #SFD10 on the Twitters. It’s the usual recipe: 12 delegates from around the world and 9 companies (start-ups and established companies alike) explaining their vision on the storage market and how their products work. I love these events because in three days time we’ll be bombarded with a whole lot of information on existing and upcoming storage tech. In my mind, there’s no other event with this information density: afterwards it usually takes a couple of days to let it all trickle through. Or as we say in Dutch, “make cheese out of it”… (of course it’s about cheese)

Today EMC announced their new and improved mid-range storage at EMCWorld: say hello to Unity! It will be replacing the VNX1 and VNX2 systems with simple, modern flexible and affordable new platform and can be purchased in either an all-flash or hybrid configuration. There are quite a lot of differences between both the new Unity and the old VNX systems, with a number of improvements (available at GA or later) that make me really, really happy. Let’s dive in!

I’m just about ready to start my 18 hour trip to Las Vegas for EMCWorld 2016. The first hop to Miami should be a relatively quiet one (if I can get some sleep); on the second I’ll start to prepare for the madness that will ensue next week. The agenda is packed with good events and new product launches…

When deleting an Isilon folder, you might come across some peculiar behavior. When browsing with a file explorer to an SMB share and deleting a folder, the operation apparently succeeds and the folder disappears. When refreshing the share however, the folder is back. Resorting to an SSH session to delete the folder, you get an Operation not permitted error and the rm/rmdir command fails.
