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!
BANG! The members of EMC Elect 2014 are officially announced! This is the second year of the EMC Elect, a recognition program started in 2013 for those people sharing (technical) expertise and evangelizing about EMC products and solutions. Since it’s an annual program, being a member of EMC Elect 2013 does not guarantee membership of the EMC Elect 2014. Read on to learn a bit more about the nomination process, the assessing/judging of the nominees, who can call him/herself EMC Elect for 2014 and what’s on the agenda.
XtremIO is the new all-flash array from EMC, announced not too long ago. Flash has an enormous performance advantage over traditional spinning disks. Although there are no moving parts in a solid state drive, they can still fail! Data on the XtremIO X-Brick will still need to be protected against one or multiple drive failures. In traditional arrays (or servers) this is done using RAID (Redundant Array of Independent Disks). We could simply use RAID in the XtremIO array, but SSDs behave fundamentally different compared to spinning disks. So while we’re at it, why not reinvent our approach of protecting data? This is where XtremIO XDP comes in.
Over the last couple of months I’ve been busy phasing out an old EMC CLARiiON CX3 system and migrating all the data to either newer VNX and/or Isilon systems. The hard work paid off: the CX3 is now empty and we can start to decommission it. But before we ship it back to EMC we need to employ a type of CLARiiON data erasure to make sure data doesn’t fall into wrong hands.
The storage market has gradually been using more and more flash to increase speed and lower cost for high I/O workloads. Think FAST VP or FAST Cache in a VNX or SSDs in an Isilon for metadata acceleration. A little bit of flash comes a long way. But as soon as you need enormous amounts of flash, you start running into problems. The “traditional” systems were designed in an era where flash wasn’t around or extremely expensive and thus simply weren’t designed to cope with the huge throughput that flash can deliver. As a result, if you add too much flash to a system, components that previously (with mechanical disks) never were a bottleneck now start to clog up your system. To accommodate for this increased usage of flash drives the VNX system was recently redesigned and is now using MCx to remove the CPU bottleneck. But what if you need even more performance at low latency? Enter EMC XtremIO, officially GA as of November 14th 2013!
EMC sends out a VNX Uptime Bulletin every quarter to update customers on best practices and fixes which will help you in achieving the maximum possible uptime and robustness for your VNX. You can subscribe to them as you would to with any other ETA (EMC Technical Advisory): log in at http://support.emc.com, go to Support by Product, open your product page (in this case the VNX) and click “Get Advisory Alerts” to subscribe. This bulletin discusses pools and LUN ownership, vault drives, software versions, etc.
