Some Things I’m Working On

I wanted to take just a brief moment and let everyone know about a few articles that I’ve got “in the pipeline” for the site. If there is one—or more—of these articles that looks particularly interesting, speak up in the comments.

Here are the articles that are currently under development:

  • An update to the Solaris-AD integration instructions: Last time I ran through these instructions I came across a number of discrepancies and little “gotchas.” I need to incorporate the workarounds into the integration instructions and publish a new version.
  • A brief blurb on NetApp OSSV: NetApp’s Open Systems SnapVault (OSSV) is a pretty cool technology, so I want to take a quick look at setting it up. I’m also exploring to see what kind of unique synergies may arise from using OSSV in a VMware environment.
  • Restricting access to ESX Server when using AD integration: As reader Scott Garrett points out in this comment to an earlier article, ESX Server’s version of sshd doesn’t support the UsePAM directive. This prevents us from using group membership in Active Directory to control access to ESX Server’s Service Console. Or does it? I have a hunch that there may be at least one workaround for this problem; once I’ve tested it, I’ll document it here.
  • New iSCSI functionality in ESX Server 3.5: VMware appears to have refreshed the software iSCSI initiator in ESX Server 3.5, so I want to take a closer look at and discuss here some of this new functionality.

That’s it for now, although I’m certainly open to other items that pique reader interest. Feel free to submit your suggestions in the comments. Thanks!

    The below are particularly interesting to me.

    New iSCSI functionality in ESX Server 3.5 – from what I have read, jumbo frames are still not supported with the software initiator. Is load balancing possible yet? Is the initiator still based on the cisco Linux iscsi initiator, or was it rewritten?

    Restricting access to ESX Server when using AD integration

    A brief blurb on NetApp OSSV – I would be particulalry interested in the VMware integration of this product.

    Thanks for the great articles!

    Ron,

    I would guess you’re referring to the problems we ran into with CentOS 5. I hadn’t planned on tackling that one anytime soon, but I’ll see what I can do. Thanks for letting me know!

    Wade,

    I can definitely confirm that jumbo frames are not supported for iSCSI or NFS; only for VM data networking.

    I can also verify that the software iSCSI initiator is based on different code as well. I’m not clear yet on what new functionality is included; I’ve seen references to support for MCS (Multiple Connections per Session) and multipathing.

    Thanks for the feedback!

    Hi Scott,

    Very much looking forward to your next Solaris AD integration article. I am in the process of doing up a proposal for this in our business and am giving a choice between the open source solution and a commercial solution. Are there any specific changes that we can expect in the next version?

    Thanks for your guides!

    Dave,

    A preview of some of the changes you’ll see in version 4 of the Solaris-AD instructions can be seen in this posting:

    http://blog.scottlowe.org/2007/11/27/some-notes-on-solaris-ad-integration/

    Nothing new or earth-shattering, just a clarification of the existing procedure(s).

    Thanks for reading!

    I’d be interested in hearing about the new iSCSI functionality in ESX Server 3.5

    I am interested in anything you have on differences between iSCSI on 3.01 and 3.5. I have a Netapp Fas2020 presenting iSCSI disk to ESX 3.01 and it works fine. Can’t see disks on esx 3.5. Thought it might be the firewall but doesn’t seem to be. Have call open with Netapp, awaiting feedback, having sent on output from ESX host utilities 3.1. Any thoughts you have would be appreciated.
    Thks.
    Brian.
