VNXe OE 2.4 and 2.5″ form factor disks


Once again I had a chance to play around with some shiny new hardware. And once again the hardware was VNXe 3300 but this time it was something that I hadn’t seen before: 2.5” form factor with 46 600GB 10k disks. If you have read about the new RAID configurations in OE  2.4.0 you might figure out what kind of configuration I have in my mind with this HW.

In this post I will go through some of the new features introduced in VNXe OE 2.4.0, do some configuration comparisons between 3.5” and 2.5” form factors and also between VNXe and VNX. Of course I had to do some performance testing as well with the new RAID configurations so I will introduce the results later in this post.

VNXe OE 2.4.0.20932 release notes

Customizable Dashboard

Along with the new OE came the ability to customize UI dashboard. The look of the Unisphere UI on new or upgraded VNXe is now similar to Unisphere Remote. You can customize the dashboard and also create new tabs and add desired view blocks to the tabs.

Jobs

Some of the operations are now added as background jobs and you don’t have to wait that the operation is finished. Steps of the operations are also more detailed when viewed from the jobs page. Number of active jobs is also shown next to the alerts on the status bar dependent on what page are you on.

New RAID configurations

Now this is one of the enhancements that I’ve been waiting for because VNXe can only utilize four RAID groups in a pool. So with the previous OE this would mean that datastore in 6+1 RAID 5 pool could only utilize 28 disks. Now with the 10+1 RAID 5 pool structure datastores can utilize as many as 44 disks. This also means increased max iops per datastore. 3.5” form factor 15k disk RAID 5 pool max iops is increased from ~4900 to ~7700 and with 2.5” form factor 10k disk RAID 5 pool max iops is increased from ~3500 to ~5500. Iops is not the only thing to be looked at. Size of the pool matters too and not to forget the rack space that the VNXe will use. While I was sizing the last VNXe that we ordered I made this comparison chart to compare the pool size, iops and rack space with different disk form factors in VNX and VNXe.

comparison

Interesting setup with the VNXe 3150 and 2.5” form factor disks is the 21TB and 5500 iops packed in 4U rack space. VNXe 3300 with same specs would take 5U space and VNX5300 would take 6U space. Of course the SP performance is a bit different between these arrays but so is the price.

Performance

I’ve already posted some performance test results from VNX 3100 and 3300 so I added those results to the charts for comparison. I’ve also ran some tests on VNX 5300 that I haven’t posted yet and also added those results on the charts.

There is a significant difference in the max throughput between 1G and 10G modules on VNXe. Then again the real life test results are quite similar.

These results reflect the performance of the environment that the tests were ran in. Results may vary depending on the hardware and how the environment is configured.


EMC World 2012: Wrap-up


Week after the EMC World and my brain is still digesting all the information from the conference. I started going through my notes from last week and thought how I can squeeze everything in one post. So I decided to do separate posts about Hands-On Labs and Social Networking. In this post I will go through some of the new product announcements and also other interesting things that I witnessed last during the EMC World.

A couple of interesting facts that Joe Tucci mentioned on his keynote:

  • E and M on EMC comes from the founders names: Richard Egan and Roger Marino.
  • The first “EMC World” was held in 2001 and was called “EMC wizards” having about 1300 customers attending.

Announcements

Pat Gelsingers keynote was all about new product announcements and demos. Chad Sakacc did a great job with the demos and also managed to scare everyone with a big explosion on his second demo. There were actually 42 new products and technologies announced and one of those was very interesting: VNXe 3150. I already did a quick post about VNXe 3150 highlights during the EMC World.

Another really interesting announcement was the VNX software upgrade that goes by the name “Inyo” at this point and will be available in the second half of 2012. This brings several new enhancements and features to VNX. Two of those that I’ve been waiting since the FAST pools were initially introduced: mixed pools and automatic pool rebalancing. Also a very welcomed addition is the Storage Analytics package. Chad Sakacc and Sean Thulin have written great posts covering the “Inyo” and its new features.

Session highlights

One interesting session that I attended was titled as “VNX & VNXe: Unisphere future visions and directions”. The main topic was the future single Unisphere for VNX and VNXe combining simplicity and flexibility. This will bring the VNXe simplicity and application-centric storage management to VNXe but will not take away the flexibility of VNX and the ability to manually create datastores and LUNs. There will also be some improvements to serviceability: simplifying self-service and problem notifications. Downloading updates and scheduling those using Unisphere is one of the major improvements that were mentioned about the serviceability.

In the future both VNX and VNXe can be managed using Unisphere remote. There will also be performance monitoring, history and analytics available in the future Unisphere remote. Last but not least a mobile app (monitoring first) and a unified cli are also on the way.

Chad’s World

Once again Chad and Wade filled the room with their entertaining “Chad’s World Live II – The Comeback Tour” show. And of course they had something face melting to announce: Project Razor
