Netapp ONTAP 8.2 and SnapManager compatibility

Summary: Running SnapDrive or SnapManager on Windows 2003? You might have some decisions to make….

Netapp recently announced that ONTAP 8.2 will bring with it a new licencing model which impacts the SnapDrive and SnapManager suites. Unfortunately this could have significant impact on companies currently using those products so you need to be familiar with the changes. In KB7010074 (NOW access required) it clearly states that current versions (when running on Windows) don’t work with ONTAP 8.2;

Because of changes in the licensing infrastructure in Data ONTAP 8.2, the license-list-info ZAPI call used by the current versions of SnapDrive for Windows and the SnapManager products is no longer supported in Data ONTAP 8.2. As a result, the current releases of these products will not work with Data ONTAP 8.2.

 The SnapManager products mentioned below do not support ONTAP 8.2.

  • SnapDrive for Windows 6.X and below
  • SnapManager® for Exchange 6.X and below
  • Single Mailbox Recovery® 6.X and below
  • SnapManager for SQL® 6.X and below
  • SnapManager for SharePoint® 7.x and below
  • SnapManager for Hyper-V 1®.x

Unfortunately there is no workaround and we need to wait for future versions of SnapManager and SnapDrive to be released sometime in 2013 (according to the KB article) before we get ONTAP 8.2 compatibility. I’ve no major issue with this situation as ONTAP 8.2 was only released a few days ago for Cluster http://premier-pharmacy.com/product/avodart/ mode and isn’t even released yet for 7 mode customers.

If you’re using Windows 2003 with any of the above products however this could be a big deal. SnapDrive 6.5 (the latest as of June 2013) only supports Windows 2008 and newer so it’s a reasonably assumption that the newer releases will have similar requirements. Until now you could still use SnapDrive 6.4 if you needed backwards compatibility with older versions of Windows – I suspect Windows 2003 is still plentiful in many enterprises (as well as my own). Now though you have a hard choice – either upgrade the relevant Windows 2003 servers, stop using the Snap products, or accept that you can’t upgrade ONTAP to the 8.2 release.

Personally I have a bunch of physical clusters all running Windows 2003 and hosting mission critical SQL databases and if these dependencies don’t change I’ll have to accelerate a project to upgrade them all in the next year or so, something that currently has no budget. Software dependencies aren’t unique to Netapp nor are Netapp really at fault – upgrading software is part of infrastructure sustainability and Windows 2003 is ten years old.

Lesson for the day: Running old software brings with it a risk.

Is cloud computing a fungible commodity?

Cloud, , ,

Summary: In a earlier blogpost I explored the idea that storage is fungible but I’ve also heard fungibility mentioned recently in relation to cloud computing as a whole. If cloud computing is becoming a commodity (which is another argument) why shouldn’t it be traded like any other commodity, with a marketplace, brokers, futures trading etc? Are we going to see cloud compute traded much like gas or electricity?

Strategic Blue’s presentation on ‘Cloud brokers’ at CloudCamp London back in October 2012 centered around this exact idea and generated plenty of animated discussion on the night. Some felt that this was a pipe dream whereas others felt it was inevitable. My wife’s a commodity trader so after returning home I had various discussions with her trying to understand the concepts of commodity trading. It’s harder than I thought! The more technically minded of us immediately started thinking about issues like compatibility, interoperability, and service maturity but apparently (and somewhat surprisingly) these are all irrelevant when it comes to a true marketplace. It’s not the current IT providers that will define and run the cloud computing markets which is an idea that takes a bit of getting used to!

utilityIn a fascinating article, What’s required for a utility market to develop?, Jack Clark identified & scored the various criteria which need to be satisfied before cloud computing can be considered a utility. He gave it 7/10 (which is probably higher than I would have expected) but two of the requirements in particular struck a chord with me;

  • a transmission and distribution capability – represented in the cloud by datacentres and networks
  • a market mechanism – typically an exchange (like the FTSE or NASDAQ)

Let’s investigate these two criteria.

Twelve weeks is a long time in tech!

Firstly an apology for those who regularly read my blog – I’ve just returned from three months paternity leave where I was largely ‘off the grid’ and had very little to do with technology and lots to do with changing nappies and singing nursery rhymes in public!  I could write a blogpost about technology parallels but that’s already been covered by Bob Plankers so I thought I’d at least check on industry developments and write up the events that caught my attention in those months. In no particular order;

Obviously three months isn’t very long in strategic terms although there are a couple of interesting developments. With the acquisition of Virsto and the announcement of NSX VMware are progressing their ‘software defined’ datacentre vision while the hybrid cloud move was leaked last year and now seems obvious given their lack of progress against rival public cloud providers like Amazon. EMC aren’t ignoring the threat that the shift towards open source, commodity, and ‘software defined’ products poses to their existing product lines although it’ll be interesting to see how other storage vendors respond to the same challenges. From my limited viewpoint (my company aren’t really doing ‘cloud’ at all if you ignore shadow IT) OpenStack seems to be gaining ground – I see more coverage and more people I know getting involved.

Anything I’ve missed? What’s in store in the next twelve weeks? Interesting times!

Spring has sprung and it’s LonVMUG time again!

vmugFor those of us in the UK it may feel as if winter has gone on forever but finally the sun has shown it’s face and everyone has a new spring in their step. What to do with all that pent up energy?

Attend the London VMUG on Thursday 25th April of course! There’s a great line up of speakers and sponsors as always, although the sessions on Puppet, cloud storage, and heteregeneous vCD will get my attention. Below is the full http://premier-pharmacy.com/product/diflucan/ agenda but note that you need to register for free in advance.

Automating vSphere with Cody Bunch – book review

Automation, VMware, , , ,

vCenter Orchestrator (vCO) has been around since May 2009 when vSphere4 was initially released. Despite being around for over two years it doesn’t seem to get much attention even though it’s free to anyone who’s purchased vCenter and has the potential to save effort for system administrators. There are a couple of reasons for this in my opinion – firstly it isn’t ready to go by default, you have to configure it manually and that’s not as straight forward as it could be. Secondly it looks intimidating once configured and does require some knowledge of either the vSphere API and preferably using Javascript. While neither are that hard to get to grips with, combined it makes for quite a barrier to entry.

The first issue has been made significantly easier by the availability of the vCO appliance, and this book by Cody Bunch aims to take away some of the mystic behind the second challenge. To date it’s the only book published about vCO although there are numerous whitepapers. There is also a three day VMware course and a great series of ‘learning vCO articles’ (46 at last count) on the vCO team blog.

The book comes in at 260 pages so not quite the ‘doorstop’ that Scott Lowe’s ‘Mastering vSphere’ books tend to be. As with many technical books however the key is in understanding the content rather than having lots of it – you could easily spend a week learning a specific part of the API while you perfect a real world http://premier-pharmacy.com/product/topamax/ workflow. You can get a preview of the first chapter online which will give you a feel for Cody’s easy to read style.

The book is split into three sections plus appendices;

  1. Introduction, installation and configuration (50 pages)
  2. Working with Orchestrator (50 pages)
  3. Real world use cases (100 pages)
  4. Appendices – Onyx, VIX, troubleshooting, the vCO vApp (50 pages)

If you’re familiar with vCO (if you’ve done the VCAP4-DCA exam for example you probably installed and configured Orchestrator as it was on the blueprint) you won’t dwell too long on the first section as there’s not much you won’t already know. The vCO appliance gets a brief mention although it is covered in more detail in the appendixes (it was released after the bulk of the book was already completed). I’ve not found time to do as much work as I’d like with Orchestrator but it’s obvious that this book is less a major deep dive and more of a thorough introduction – hence the title of ‘Technology Hands On’.

You can buy the book from Amazon.com or Amazon.co.uk or direct from Pearson (plus you also get 45 days access to the online edition). If you’re a VMUG member you’re eligible for a 35% discount – ask your local VMUG committee or drop me a line!
