SvSAN 6: now with memory and SSD caching

StorMagic SvSAN schematicA 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.

FlashBlade: custom hardware still makes sense

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?

PureStorage FlashBlade

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…

Cloudian HyperStore: manage more PBs with less FTE

Cloudian LogoIf 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!

ScaleIO Architecture and failure units

ScaleIO logoI had the opportunity to play with a new EMC product last week: ScaleIO. It’s definitely not a new EMC product (I troubleshooted the 1.31 version and EMC released 2.0 at EMC World 2016) but I just hadn’t had the honor to work with one of those systems yet. ScaleIO is a software-defined storage solution that uses the local disks in your commodity server and shares these out as block LUNs across the Ethernet. Which means this architecture can scale pretty well, both on capacity and performance, using hundreds (if not thousands) of servers and disks.

Breaking down storage silos with Primary Data DataSphere

Primary Data logoPrimary Data unveiled there DataSphere product at VMworld US back in August 2015. With DataSphere, Primary Data virtualizes the different types of storages in the datacenter, creating a global dataspace and breaking down the traditional silos of storage. It attempts to do for storage what VMware did for computing: any piece of data can reside on any storage, movable at any time, without interruption. In essence, increasing data mobility by decoupling the logical storage from the physical hardware. The team gave us an update on their product at Storage Field Day 10, so here goes!

Simplicity with Kaminario Healthshield & QoS

Kaminario LogoKaminario 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?

Ready for Storage Field Day 10!

SFD LogoIn 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)

Say hello to EMC Unity!

Unity system EMCWorld 2016Today 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!

On my way to EMCWorld 2016!

I’m just about ready to start my 18 hour trip to Las Vegas for EMCWorld 2016.EMCWorld 2016 first flight AB7000 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…

Deleting an Isilon folder – Operation not permitted

Deleting an Isilon folder - Operation not permittedWhen 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.
