Hands-on with VNXe 3200: Initial setup


Here I go again. About two years ago I started writing a series of blog posts about my hands-on experience with newly released VNXe 3300. At that time the VNXe 3300 was just released and there wasn’t that much documentation out there. So I did lots of testing and had to make my own “best practices”. The previous blog series is one of the reasons why I now have a chance to test and write about the VNXe 3200.

On June 10 Chad published this blog post: “Summer Gift Part 2 – 10 VNXe arrays free to play with for volunteers!”. I was surprised to find myself mentioned on the post and even more surprised to find out that one of the devices was reserved for me. So while I was on vacation last week the test unit arrived:

  • VNXe 3200 – 2U Form Factor/12 Drive DPE
    • 3.5” Drives
    • 6 x 600GB 15K Pack
    • 3 X 100GB eMLC Flash Drives (for FAST auto-tiering)
    • 2 X 100GB eMLC Flash Drives (for FAST Cache)
    • 9TB Raw Capacity

VNXe 3200 is basically a combination of the new VNX MCx multicore technology and the old VNXe OE/Unisphere. I won’t go through all the new features but there are a few worth mentioning:

  • Multi-core RAID (MCR), Multi-core Cache (MCC), Multi-core Flash (MCF)
  • “Active/Active” file
  • Single container for block and file
  • Linux-based platform

More details about the new features on EMC VNXe Series website.

Unboxing

Well not much to write about this: Install rack rails, lay DPE on those, connect cables and the VNXe was ready for configuration. However, this was something I hadn’t seen before with the previous VNXe:

Quick look in the installation documentation and it revealed to be a power adapter for the front LED-lights: image

Initial setup 

There have been several new versions of the VNXe OE since my first VNXe blog post but the “Unisphere Configuration Wizard” still looks similar. Going through the wizard takes about 10 minutes but I skipped most of the configurations as usual. I prefer to upgrade the VNXe to the latest software version before I do any configurations to new devices. After the configuration wizard is completed you will get a popup and you will be directed to the EMC support website where the latest version can be downloaded.

Conclusions

Even though there is totally new hardware running under the hood Unisphere still looks and feels the same as on the latest software vesion on VNXe 3100/3150/3300. I still agree that VNXe is simple to install and configure. Of course I haven’t configured any storage pools or iscsi servers yet. I’ll cover those on the next posts. Also performance and some of the new features will be reviewed later.

EMC World HOL sneak preview


Once again it’s time for EMC World; new product releases, breakout sessions, labs, networking, wandering around the show floor and of course some fun too. Breakout sessions will be recorded and those can be accessed after the conference but at least most of the hands-on labs are created just for the EMC World. So take an advantage of the ease of testing and evaluating EMC products in an isolated environment without needing to worry about messing up anything. It’s a really good opportunity to get hands on experience and see how things really work.

HOL1

The setup

Labs are running on VCE Vblock architecture based infrastructure at EMC North Carolina data center. The storage used to serve the content is VNX and XtremeIO and of course to make it all work together vSphere 5.1 & vCD are also utilized.

There will be two screens at the front of the HOL where the live performance of the environment can be monitored. There will also be product specialists demoing and answering questions about the HOL cloud infrastructure.

HOL2

There will be 200 seats for HOL attendees.

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.

Disclaimer

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 Elect – badge of honor


Two months ago EMC Elect – community driven brand recognition program – and its ten first “founding” members were introduced. The idea of the program is similar to Microsoft MVP and VMware vExpert programs.

Two of the masterminds behind this program are Matthew Brender and Mark Browne. Here is Matthew’s short summary about the program.

EMCElectSummary

Today EMC announced the first 75 community members that were selected to the EMC Elect 2013 program by their contributions in the past year. I’m very honored to be one of those 75 top contributors that were selected. Thanks to all my followers and other community members! Here is the official list of all members: The EMC Elect of 2013 – Official Directory.
