• EMC World 2015 I’m at EMC World in Las Vegas this week and it’s been fantastic so far.  I’m excited about the new 40TB XtremIO X-bricks and how we might leverage that for our largest and most important 80TB oracle database, also excited about possible use cases for  the Virtual VNX in our small branch locations, and all … Continue reading EMC World 2015
  • Comparing Dot Hill and EMC Auto Tiering The problem with auto tiering in general is that a large amount of hot I/Os is “hot” only for a brief moment in time. Workloads are not uniform across an entire data set constantly and if the data isn’t moved in real time it’s very likely that hot data will be accessed from capacity storage. … Continue reading Comparing Dot Hill and EMC Auto Tiering
  • Troubleshooting NAS Discovery issues on EMC Ionix Control Center (ECC) We recently converted two of our existing VNX arrays to unified systems, and I was attempting to add our newly added NAS to Control Center.  I went through the normal assisted discovery using the ‘NAS Container’ option.  Unfortunately, I got an error in the discovery results window.  Here’s the error I saw: SESSION_ACTION: Discover  [4]  MO Type = … Continue reading Troubleshooting NAS Discovery issues on EMC Ionix Control Center (ECC)
  • Gartner’s Market Share Analysis for Storage Vendors Here’s an interesting market share analysis by Gartner that was published a few months ago:  http://www.gartner.com/technology/reprints.do?id=1-1GUZA31&ct=130703&st=sb.  It looks like EMC and NetApp rule the market, with EMC on top.  Below are the key findings copied from the linked article. EMC and NetApp retained almost 80% of the market. They were separated by more than $2 … Continue reading Gartner’s Market Share Analysis for Storage Vendors
  • VNX vs. V7000 Like my previous post about the XIV, I did a little bit of research on how the IBM V7000 compares as an alternative to EMC’s VNX series (which I use now).  It’s only a 240 disk array but allows for 4 nodes in a cluster, so it comes close to matching the VNX 7500’s 1000 disk … Continue reading VNX vs. V7000
  • VNX vs. XIV I recently started researching and learning more about IBM’s XIV as an alternative to EMC’s VNX.  We already have many VNX’s installed and I’m a very happy EMC customer, but checking out EMC’s competition is always a good thing.  I’m looking at other vendors for comparison as well, but I’m just focusing on the XIV for this post. … Continue reading VNX vs. XIV
  • Upgrading EMC Ionix Control Center from Update Bundle 12 (UB12) to Update Bundle 14 (UB14) Below are the steps I just took to upgrade our ECC environment from UB12 to UB14. There are quite a few steps and EMC has this process documented very well. Every install file and patch has it’s own readme file with detailed installation instructions along with additional info about special considerations depending on your environment. … Continue reading Upgrading EMC Ionix Control Center from Update Bundle 12 (UB12) to Update Bundle 14 (UB14)
  • What’s new in EMC Control Center Update Bundle 14 (UB14)?

Added support for Oracle 11g. Added Oracle 64-bit support in ControlCenter for 64-bit operating … Continue reading What’s new in EMC Control Center Update Bundle 14 (UB14)?
  • First day at EMC World 2013 It’s been a great first day at EMC World 2013 so far.  I’ve been to three breakout sessions, two of which were very informative and useful. I focused my day today on learning more about best practices for the EMC technologies that I already use.  I’m not going to go into great detail now as … Continue reading First day at EMC World 2013
  • Magic Quadrant for Storage Vendors I was reading over the Gartner report today that dives into specifics on the strengths and weaknesses of the big players in the storage market.  The original Gartner article can be viewed here: http://www.gartner.com/technology/reprints.do?id=1-1EL3WXN&ct=130321&st=sb. It came as no surprise to me that EMC was ranked as the market leader, with NetApp as #2, Hitachi #3, … Continue reading Magic Quadrant for Storage Vendors
  • What’s new in FLARE 32? We recently installed a new VNX5700 at the end of July and EMC was on-site to install it the day after the general release of FLARE 32. We had planned our pool configuration around this release, so the timing couldn’t have been more perfect. After running the new release for about a month now it’s proven … Continue reading What’s new in FLARE 32?
  • ProSphere 1.6 Updates ProSphere 1.6 was released this week, and it looks like EMC was listening!  Several of the updates are features that I specifically requested when I gave my feedback to EMC at EMC World.  I’m sure it’s just a coincidence, but it’s good to finally see some valuable improvements that make this product that much closer to being … Continue reading ProSphere 1.6 Updates
  • EMC World 2012 – Thoughts on preparing for a VDI deployment We’re in the process of testing the deployment of VDI now so I attended a session about preparing for a deployment.   As I mentioned in my previous post, I’m not an expert on any subject after attending a one hour session, but I thought I’d share my thoughts. The most important take away from the session … Continue reading EMC World 2012 – Thoughts on preparing for a VDI deployment
  • EMC World 2012 – Thoughts on Isilon I’m at EMC World in Las Vegas and I finished up my first full day at EMC World 2012 today.  There are about 15,000 attendees this year, which is much more than last year and it’s obvious. The crowds are huge and the Venetian is packed full.  Joe Tucci’s Keynote was amazing, the video screen … Continue reading EMC World 2012 – Thoughts on Isilon
  • Performance Data Collection/Discovery issues in ProSphere 1.5.0 I was an early adopter of ProSphere 1.0, it was deployed at all of our data centers globally within a few weeks of it’s release.  I gave up on 1.0.3, as the syncing between instances didn’t work and EMC told me that it wouldn’t be fixed until the next major release.  Well, that next major release was … Continue reading Performance Data Collection/Discovery issues in ProSphere 1.5.0
  • How to troubleshoot EMC Control Center WLA Archive issues We’re running EMC Control Center 6.1 UB12, and we use it primarly for it’s robust performance data collection and reporting capabilities.  Performance Manager is a great tool and I use it frequently.

If you install this new MacOS 10.7 (Lion) release, it will cause the data movers in your Celerra to reboot which may result in data unavailability. Please note that your Celerra … Continue reading Critical Celerra FCO for Mac OS X 10.7
  • Auto generating daily performance graphs with EMC Control Center / Performance Manager This document describes the process I used to pull performance data using the ECC pmcli command line tool, parse the data to make it more usable with a graphing tool, and then use perl scripts to automatically generate graphs. You must install Perl.  I use ActiveState Perl (Free Community Edition) (http://www.activestate.com/activeperl/downloads). You must install Cygwin.  … Continue reading Auto generating daily performance graphs with EMC Control Center / Performance Manager
  • Filesystem Alignment You’re likely to have seen the filesystem alignment check fail on most, if not all, of the EMC HEAT reports that you run on your windows 2003 servers.  The starting offset for partition 1 should optimally be a multiple of 128 sectors.  So, how do you fix this problem, and what does it mean? If … Continue reading Filesystem Alignment
