The VMguy

Better late than never.  There were some really good (and not so good) technical reads this past month:

VMware vShield Zones – Reviewers Guide – If you haven’t figured this out yet, pay close attention to the Reviewers Guides.  If you have even slightly thought of trying out a product or technology, the reviewers guide is the next best thing to having an engineer over your shoulder walking you thru the product.  This is a really good one on Zones.  I learned quite a few things about the product that I was unaware of.  It’s a great read if you need to lock down and firewall off your VMs (or if you just want to learn how the VMs talk to each other).

Performance Brief for IBM WebSphere Application Server 7.0 with VMware ESX 4 on HP ProLiant DL380 G6 Servers – This is a very specific paper on running Websphere on HP servers.  I did find some interesting bits in it however.  Specifically, configuration tips to maximize performance running Websphere in a VM.  The performance metrics should also be evaluated if you want to run Websphere on any hardware platform (perhaps even IBM).

Best Practices for Running vSphere on NFS Storage – I’m currently in a documentation war with my EMC Channel SE who swears by running VMware on NFS (You still have to convince me Steve, I’m a block-IO bigot).  This is a must-have for all Admins running VMware on NFS.  It’s also a really good guideline if you want to compare performance between file-level or block-level IO in your VMware environment and make sure your making an accurate decision.  My favorite section of this paper: “Previously thought to be Best Practices.”  Every best practice white paper should have that to debunk outdated information.  Outstanding work VMware!

PVSCSI Storage Performance -This is a paper I was waiting to see.  It compares the performance of the PVSCSI adapter to the LSI Logic adapter.  I guessed pretty close on the outcomes.  The PVSCSI adapter does perform better under higher IO workloads (some have stated only use it >2000 IOPs.)  The only thing I didn’t like about the test was that RDMs were used.  VMware has argued for the last few years that high-performance should not be a requirement for using RDMs.  So why not use what the majority of customers use in their environments?

RIM BlackBerry Enterprise Server on VMware Virtual Infrastructure Deployment Guide – I really liked and hated this paper.  I liked it because it has some really good best practices and deployment tips depending on the size of the environment.  I hated it because it definitely contains errors: Table 2 shows a BES server with 23% utilization on ESX 3.5, Table 3 shows a BES server with 27% utilization under ESX 4, Figure 12 says the CPU load went down from 27 to 23 going to vSphere – not according to your tables kids.

That will do it for this month’s White Paper Review.  We’ll see you next month and look for more great technical information.

By now, most of you know how Site Recovery Manager works.  SRM requires a SRA (Storage Replication Adapter) which is basically a translator to allow SRM talk directly to the storage arrays.  6 of the SRAs were updated on VMware’s download site for SRM in January.  They were:

Dell EqualLogics, Version 1.0.2, Released 01/20/2010

EMC Celerra, Version 4.0.17, Released 01/29/2010

Fujitsu ETERNUS SF AdvancedCopy Manager, Version 1.3| Released 01/29/2010

IBM DS4000/5000, Version 01.01.35.05, Released 01/15/2010

IBM N-series SAN Adapter, Version 1.4.2, Released 01/07/2010

LSI, Version 1.01.30.05, Released 01/21/2010

You can find the updated SRAs on the SRM download site here.  As always, please check to make sure these updates are necessary for your environment.  I would have included the release notes but unfortunately the vendors are not keep track of them.  Upgrade at your own risk, and if you do, please test your recovery plans out fully with the new adapters.

Update: Some readers are reporting issues with the links on this page.  At 10:54 EST this Sunday morning it appears that the technical section of VMware’s web site is offline.  I’ll check it back in a couple hours to see if they have come back and update the article accordingly.

Update: It appears the links are back.  Be aware they may be flaky if VMware is working on the site today.

Anti-Virus Deployment for VMware View – Great article on what to consider when deploying an anti-virus solution for your View desktops.  Great reading on how to best protect your desktop VMs.  My favorite part is the detailed exclusion list for the anti-virus scanners – very helpful.

Analysis of IBM System x3850 M2 Performance and Scalability with VMware vSphere 4 and SAP Solutions – a very specific read but has some very nice scailibility charts in it for the IBM x3850.  There’s also a nice listing of the optimized IBM BIOS settings on the server.

ESRI ArcGIS Server 9.3 for VMware Infrastructure – a good read if you are deploying the ESRI ArcGIS mapping software in your environment.  Very specifics on configuration of that software on ESX 3.5.

VMware View 4 & VMware ThinApp Integration Guide – A very nice paper on how to integrate ThinApp packages into pools of desktops in View.  It has a lot of items to consider when deploying apps this way.  I’m personally hoping for some native VMware integration coming in the future.

Application Registration with VMware ThinApp – Here’s the question: how can I associate a specific file type with a ThinApp’ed application so when I click the file, it opens in the ThinApp’ed App?  Bingo, the doc goes through how to set this up in your environment on virtual or physical desktops.

I’m usually not a very controversial writer but this point has been bugging me today.  We’ve all heard about the VMware-Cisco-EMC alliance and how they have begun selling their vBlocks.  Let not forget Oracle’s acquision of Sun (which I read referred to as Sunacle – hilarious).  Sunacle will be able to sell hardware and a lot of software combined.  Now, just today, I read an article about Microsoft teaming with HP to build unified solutions for datacenters.  Solutions with servers, networking, storage and, of course, Microsoft software.  I definitely think there are some advantages to this.  From a support standpoint, all of these solutions will be rock solid.  All of the hardware and software in use is known by the support staff.  This removes a vast number of variables that we introduce when we architect our own solutions in our datacenters.  They will be much easier to troubleshoot and should be more reliable overall.

But what if we want to change our vendor?  Many of us have done this in the past.  Ever changed your storage vendor?  Ever change your server hardware vendor?  Many of us know the pains involved to do so.  We have to learn new tools, new ways of configuring, monitoring and managing our infrastructure.  We may have to migrate applications or data to the new pieces of the datacenter.  This can be quite an undertaking requiring some dedicated project management, months of implementation work and hours of staff training.  All of that if you chose a new vendor for your infrastructure.  Now, what if you had to replace your storage, networking, server and virtualization vendor all at the same time?  What would that project look like?  Would you do it?

If Microsoft and HP decide to release Hyper-Cells (or whatever they may call them).  What if I decide I don’t like HP storage?  What options do I have then?  If I change the storage, is the rest of the solution supported?  What if I decide I don’t like any of it?  Will I still be free to choose the pieces of my infrastructure that I want?

I think the unified solutions have some great benefits to them.  I’m just not sure I’m ready for that kind of commitment…

Lots of new technical papers for the month of December:
