Storage Field Day 6 is around the corner!

Storage Field Day
The Storage Field Day Logo

Last year a little bird told me about Tech Field Day: a big knowledge sharing event where multiple vendors inform a select group of people or delegates about what’s hot, new or revolutionary in their field or lineup. There’s multiple types of Field Days: networking, virtualization and (of course) storage. Storage Field Day 6 will be held on 5-7 November 2014 in Silicon Valley and… WOOHOOO, I’m attending!

Among the presenters for this year are Avere Systems, Coho Data, NEC Storage, Nexenta Systems, Nimble Storage, PureStorage, StorMagic and Tegile. I’ll be honest: I’ve only heard of a couple of these names, so I’ve got a bit of reading up to do in the next couple of days and I can’t wait to hear what they bring to the table.

I’d like to thank the Tech Field Day team (Stephen, Claire and Tom) for inviting me and flying me to San Jose next week. I’m looking forward to an exciting and challenging week filled with tech and discussions. Keep an eye on the Storage Field Day 6 page for the live stream of the event and this page for updates during the week! And maybe I’ll sneak in a picture of the Golden Gate bridge if I get the chance… 😉

VNX2 MCx FAST Cache improvements

EMC World 2013 - Day 3 306MCx FAST Cache is an addition to the regular DRAM cache in a VNX. DRAM cache is very fast but also (relatively) expensive so an array will have a limited amount of it. Spinning disks are large in capacity and relatively cheap but slow. To bridge the performance gap there are the solid-state drives; both performance wise and cost wise somewhere between DRAM and spinning disks. There’s one problem though: a LUN usually isn’t 100% active all of the time. This means that placing a LUN on SSDs might not drive your SSDs hard enough to get the most from your investment. If only there was software that makes sure only the hottest data is placed on those SSDs and that will quickly adjust this data placement depending on the changing workload, you’d have a lot more bang for your buck. Enter MCx FAST Cache: now with an improved software stack with less overhead which results in better write performance.

VNX2 MCx Cache improvements

MCx Cache improvements Forced FlushingWhen troubleshooting performance in a CLARiiON or VNX storage array you’ll often see graphs that resemble something like this: write cache maxing out to 100% on one or even two storage processors. Once this occurs the array starts a process called forced flushing to flush writes to disk and create new space in the cache for incoming writes. This absolutely wrecks the performance of all applications using the array. With the MCx cache improvements made in the VNX2 series there should be a lot less forced flushes and a much improved performance.

EMC Elect Redefining Possible at MegaLaunch IV

(C) Sean Thulin“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…

Redefine Possible – Isilon

Redefine Possible LogoJuly 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?
