Political multichannel on ESX 4.1 and IBM XIV? What is recommended?

Hello

We are a little confused as to what the correct multi-channel strategy is when you have an IBM XIV storage.

In September, we had a glance on the HCL and VMware has recommended the RR as policy for the XIV storage as you can see in the screen below (taken on 2010-09-23):

2010-09-23.jpg

But when we looked in the HCL yesterday VMware (2011-01-26) have changed to FIXED:

2011-01-26.jpg

And when we read the latest Redbook IBM reguarding this they recommend RR for ESX 4.x

Page 225 at http://www.Redbooks.IBM.com/redpieces/PDFs/sg247904.PDF :

With ESX Version 4 VMWare begins to support a policy of alternating for Multipathing
production environments. Alternating Multipathing policy is always preferred to other
choice when attaching to the IBM XIV storage system.

So the main question is... What is the correct way to do this?

I asked IBM and they have given me an answer yet, but they're looking for him because the didn't know why VMware has changed the HCL in this regard.

Hi Henrik,

The HCL to the IBM XIV has been updated to support a policy of path of the fixed (VMW_PSP_FIXED) or Round - Robin (VMW_PSP_RR).

According to the Redbook - "alternate Multipathing policy is always best choice when attaching to system storage IBM XIV."

I would recommend using Round-Robin, because it is the preferred option.

Let me know if you have any other questions.

Kind regards

  • ESX 4.1 VAAI and IBM XIV 10.2.4... does not work?

    Hello

    We had our set XIV to level to the last code 10.2.4 allowing VAAI support. We followed everything that the http://kb.vmware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1021976 ... but still our hardware acceleration info shows is unknown or not supported.

    Does anyone have a good answer for this?

    And as I said before... We followed the F.A.Q for this so that the size of the block etc, it is the same for all data warehouses and so on.

    grateful for answers.

    You are right. I got the message of support XIV support VAAI was held for a few weeks because of a problem with it.

    It would also mean that there will be a 10.2.4a or even firmware. We had improvements planned for February 25, but was asked to wait until March 15 for an updated firmware.

  • Upgrading ESX 4.1 and 5.1 with UC VMServers

    I'm trying to find the documentation, guide or any details on this and have developed short on cisco.com and docwiki.cisco.com I hope that someone can point me in the right direction.

    To simplify my question let say, we have a current ESX 4.1 environment with VM servers running the following applications: CUCM, CUPS, CUC, UCCX. (does it matter if they are running 8.5/8.6 or 9.1?)

    If we were to move to ESX 4.1 to 5.1 What is the impact on the servers of Cisco? What are the procedures? Anything specific Cisco or a development warn that must be taken into account? And especially (can not find the answer to anywhere) we must redeploy the OVAs (from v7 to v8 to match) during and after the ESX upgrade?

    Any help would be greatly appreciated.

    Thank you!

    • In general, versions of Cisco Collaboration app mandate only the major and minor of ESXi versions they demand / support.
    • Guest OS support - Cisco's Collaboration applications that require a minimum Maintenance release (e.g. "5.1 U1' as minimum instead of"5.1"as minimum) for the application to be supported explicitly call this point on their product detailed pages.  When in doubt, consult Cisco Plan, design, implement (PDI) HelpDesk or Cisco TAC.
    • Supports hardware - version for a major/minor taken ESXi supported by Cisco's Collaboration applications, recommendation is to use the latest version of Maintenance which is also supported / recommended by the provider of servers (and storage if provider deployment to NAS/SAN).  To determine if a fix or a Maintenance of ESXi version "may" or "should" be deployed, follow the advice of these sources:

    Other "versions".

    • Version of VM (vmv) - the vmv represents the virtual hardware version. New versions of ESXi can increase the latest vmv, but ESXi versions always take care of the older versions of vmv (visit vmware.com for more information on the compatibility of the versions of vmv with ESXi versions). The "strict minimum" for Cisco's Collaboration applications is vmv4 and is usually transparent. Cisco-/ required files OVA will be for a particular version of vmv (e.g. OVAs for ESXi 5.x include vmv7 and vmv8). Unless is not a Cisco Collaboration application, customers are free to upgrade manually the vmv to a most recent vmv supported by the version of ESXi (click here for more details ).
    • File system VMFS (Virtual Machine) version - this is transparent to the applications of Cisco's Collaboration, but recommends using the latest version available for the major/minor version of VMware vSphere, ESXi, you deploy on.

    below that you have links to specific applications of version indicating compatibility with ESXi versions.

  • ESX 4.1 and 4.1U1 - do I need to upgrade?

    I recently noticed theres an ESX 4.1 update 1 on the list of downloadable products.

    And then go to the main page to download and read the details of the ISO and the ZIP, it's vague as to whether or not it applies to 4.1 ESX host.

    given that refers only s pre 4.0 and 4.0 U1 4.1 upgrade.

    We currently do not have the Update Manager gui app installed from what I can tell and im wondering what the best practices for the determination of the need to patch.

    something that can analyze existing hosts to determine the necessary adjustments.

    in the past, my experiences are to be updated simply offline using the iso on a dvd.

    then use AUVS to upgrade hosts, to upgrade your clients must be vmotioned off the coast of the esx host as the host must be in service of update/install mode patches. You can use hostupdate if you have not installed VUM but I would recommend creating VUM if you can because it really makes your life so much easier when you have to update your hosts, the vmotools, the versions of hardware and install the third-party tools such as powerpath

  • Difference between Esx v 2 and 3 and ESX 2.5 and 3.5

    Hello

    I want to know the differences between ESX V.2 and 3 and ESX 2.5 and 3.5. can someone help me on respect.

    Karthik.

    Hello

    The biggest difference between ESX 2.x and 3.x is how the virtualization of the boots as well as configurations of network virtual host.

    In ESX 2.x booted Linux then VMware took control.

    In ESX 3.x VMware started then place the unit of management within a virtual machine started.

    ESXi boots the vmkernel then starts a Posix environment in the vmkernel.

    The book of VMware ESX Server in the enterprise passes over these differences in a bit of detail, if you are interested.

  • Anyone running VMware on an IBM XIV table

    We plan to go to an IBM XIV storage array. The technology looks very cool. Wondering if someone had direct knowledge of ESX 3.5 running on these.

    Hi bobross,.

    could you please send me some details about your tested XIV config. We have 2 XIV installed since last week but are running in some numbers. When connecting more than 12 or 13 VMFS XIV stops 'responding '. Storage Vmotion is to expire, migration of vm is still not working. We see some delays start using VMFS 6 volumes in 7. Our goal was to 34 volumes served by 48 ESX servers (target approximately 600 VM). Could you tell me what was your config tested in terms of number of ESX servers and mounted VMFS volumes. The behavior occurs with VMFS big or small VMFS volumes. The same thing happens not only with the CF, but also with iSCSI.

    Were the only config works is by putting a virtualization of storage between the ESX and XIV. (we tested Falconstor and SUN Comstar). Direct connect ESX XIV gives us the problems.

  • UCS with vsphere for BFS on IBM XIV

    Hello

    It seems that the IBM XIV storage has a limitation around the minimum size of LUNS, which seems to be 17 GB. Taking into account that one of the added values of the UCS is the SAN boot using the service profiles, and that most UCS implementations rely on VMware (OS, ESXi needs barely 300 MB installation), which means a must are underutilizing the 17 GB LUNS in order to begin the ESXi, that might be a waste of money. I was wondering if anyone here found the same question to their customers and know if this also happens in other bays of disks (EMC Symmetrix for example), or only in IBM XIV.

    Thank you very much

    Dani,

    That really sound silly on a size of the LUN 17 GB min. configured but seems to be true:

    http://storagemojo.com/2011/11/01/14-things-to-know-about-XIV/

    I have never heard all these dimensions LUN min. anywhere near this size on all NetApp or EMC arrays.

    As it is a problem of table to IBM, I would say this confirming with IBM.

    Kind regards
