“Check your email ;)”. That was the first Twitter DM I read one sleepy morning in June. It’ll suffice to say, a minute later I was wide awake: I was chosen to represent the EMC Elect at the EMC “Redefine Possible” MegaLaunch event in London (UK)! I knew about these launch events because my colleague Rob attended one last year in Milan. Excitement started building and a couple of hours later I figured out I wasn’t going alone…
July 8th 2014. EMC MegaLaunch 4. Theme: Redefine Possible (or #RedefinePossible on Twitter). What previously was impossible, now is possible! Catchy theme and something that we’ve seen in IT for a number of times now. For example: In the 1990′s, who would have thought it was possible to migrate a server from one datacenter to another, possibly a couple of miles away, without downtime, in a couple of seconds?! Doing things fundamentally different, better: that’s the goal we’re always trying to achieve. So how can we apply this to Isilon?
In September 2013 EMC announced the new generation VNX with MCx technology (or VNX2). The main advantage of the new generation is a massive performance increase: with MCx technology the VNX2 can effectively use all the CPU cores available in the storage processors. Apart from a vast performance increase there’s also a boatload of new features: deduplication, active-active LUNs, smaller (256MB) chunks for FAST VP, persistent hotspares, etc. Read more about that in my previous post.
It took a while before I could get my hands on an actual VNX2 in the field. So when we needed two new VNX2 systems for a project, guess which resources I claimed to install them. Me, myself and I! Only to have a small heart attack upon unboxing the first VNX5400: someone stole my standby power supplies (SPS)!
Isilon scale-out NAS clusters (or grids) are built out of nodes or servers using (relatively) cheap commodity hardware. Compared to a traditional storage system this has the advantage that with every capacity (=disks) expansion you’re adding to the cluster, the number of CPUs, amount of RAM and network ports grows accordingly. You just add another node or server and poof: more TBs, more speed. The proprietary software OneFS then glues all those nodes together to create one single immense filesystem (up to 20PB with current drive specs). But what’s one trait of commodity hardware? You occasionally need an Isilon firmware upgrade! The LSI disk controller needs a new release once in a while, as do perhaps the front panel or the Infiniband components. This howto explains what to do to make sure you’re running the latest firmwares!
Every IT system needs a software upgrade once in a while, either to enable additional functionality or to patch some security holes. Yes, even an Isilon scale-out NAS. Good news: performing an Isilon OneFS Upgrade is peanuts! Including pre-checks and the post-checks our 3-node cluster was upgraded in less than 2 hours without downtime. Curious how to do this?
EMC World 2014 is back in town, this time with the REDEFINE punchline. After some logistic challenges to get here the show is on the road; general sessions, break-out sessions, hands on labs (HOL). So what’s up with the REDEFINE punchline? What are we redefining in the IT / data infrastructure? And what are the EMC Elect doing at EMC World when not flooding your Twitter feed?
A couple of months ago InsightIQ 3.0 was released. This new release offers improvements in the interface and under the hood, especially when paired with OneFS 7.1. Upgrading is straightforward, done in under 30 minutes and also makes sure you’re not affected by the Heartbleed bug. Start clicking!
A new quarter, a new VNX Uptime Bulletin! This month is all about target releases of code and associated bugs. It’s important to keep up to date with current code releases; not only because certain newer models of disks/modules may not be supported by old code, but also because EMC is constantly fixing known problems and bugs. This VNX Uptime Bulletin headlines with VNX OE 33 updates and continues with target code for R32 and R31.
Finally! I’ve just passed the USPEED Performance Guru exam! I first got aware of the SPEED programs during a Celerra Performance Workshop a couple of years ago. Initially it was an EMC Internal program, so I couldn’t get in without switching employers. In the beginning of 2013 this changed and EMC Partners could also enroll. Too bad I ran out of time with a mountain of projects and other training material… up until now! So what does it mean when someone is USPEED certified?
About 7 or 8 months ago we installed two 3-node Isilon clusters at a hospital destined to host PACS data. Since then it’s all quiet on the Isilon front: no hardware failures, no performance problems. No complaints there of course, but also.. slightly.. boring. FINALLY, a couple of days ago the Isilon sent us an email. “Device disconnected. Boot mirror is critical. Unhealthy Isilon boot disk. Mirror is degraded.” That kind of stuff. Woohoo, ACTION!
