  1. Why do you have multiple subnets for the ESX host NICs and the MSA NICs? The multi-vendor post (http://virtualgeek.typepad.com/virtual_geek/2009/09/a-multivendor-post-on-using-iscsi-with-vmware-vsphere.html) on iSCSI with vSphere makes no mention of splitting the NICs over multiple subnets..

    Thanks for the comment Chris! Check out HP’s Best practices guide for the MSA here Page 42 has a great picture, however it really doesnt go into “why” so… We need the ports in different subnets because all of the cables in the first subnet can be ran to one switch, while the other set can be ran to a different switch. Same with the ESX servers, all the iscsi ports in subnet A go to switch A while all ports in subnet B go to switch B…. this will create two completely redundant paths and leave no single point of failure. So in the end the reason that you need two subnets is because switch A and switch B are not connected to each other and because of that if all the SAN ports were in the same subnet (as were the esxi ports) we would run into situations where a port on the esxi server would try to access a san port that is cabled to the other switch. And because the switches do not have a path between then it would timeout and cause all sorts of problems. Let me know if you have more questions or anything, would be happy to help out more or explain in more detail.

  3. Thanks! That makes more sense and it’s nice to have the “best practices” PDF — not sure why I couldn’t find this on my own at HP… (or why my installation vendor couldn’t find it and follow the instructions in it!!!)

    Hey Justin, Just found your blog and great into on the HP p2000 iscsi san. We just had one delivered to my location the other day loaded up with 12 2tb sas disks for a total of 24tb of storage. I am going to be working with a consultant shortly on setting up the disks and partitioning it but I would like your thoughts on best way to carve up that storage. The HP p2000 will be serving two HP servers running vmware esxi 4. Each server has 8 gigabit nics.
    Anyway great blog and I am very glad I stumbled onto it.

    Much simpler to follow, and makes much more sense than the HP guide, nice one :)

    Hey do you know if the MSA2000i or P2000G3 require HP original hard drives like the Dell MD3000i does? MD3000i doesn’t take third party HDDs, and Dell’s markup on HDDs make NexentaStor look pretty awesome. So anyone tried Hitachi or Seagate Nearline SAS in those SANs?

  7. Justin says:

    I could answer your question a little better offline, but since you didnt provide a real email address ill go my best here.

    The MSA and P2000 are OEM’d from a 3rd aprty manufacturer. SAS drive from HP do come with Hp firmware on them, but as from what i understand SATA drives are just stock firmware.

    The catch is drive trays. The LFF Model SAN uses an odd tray which isnt that standard proliant 3.5″ drive sled.

    The simple answer is that it will in deep take about any sas/sata connector drive that you have.

    Hi Justin –
    I used your site extensively when setting up our SAN a while back. One question I have is that on our 2 controller iSCSI setup, I have both management ports setup on the same subnet (different IP’s of course) and connected to my LAN. After a period of time, I get the SSL error:
    “ssl_error_bad_mac_alert” if I try connecting via web browser. If I go and disconnect, say the 2nd port, I’ll be able to log in. Have you seen this?

    Hi Justin-

    Just wondering if you have tried this at all in vSphere 5.0? I had a design very similar to yours and then I came across this KB from VMware that seems to invalidate it all.


    What are your thoughts?


  10. Scott says:

    Hi Justin-

    Great post! I’m in the process of installing a P2000 SAN in my environment and I have a design almost the same as your’s. However, I came across this VMware KB that seems to invalidate your and my designs. What are your thoughts on this? I’m running vSphere 5.0 and the P2000 G3 iSCSI dual controller SAN.



  11. Jeff says:

    I’m wondering the same thing. I’ve got a P2000 on its way to my office and am wondering if I should go with/without the port binding.. In the past, I have setup an EMC VNXe SAN in the exact same configuration as described above, but this VMWare article suggests it’s a bad idea.



  12. Justin says:

    I would have to look into that article more…. that is how i have always configured things…. its how i was running the P2000 systems and its how im running my VNXe3100 as well… i have had no issues.

  13. Justin D says:

    Hey there. nice guide. in the process pretty much the same on a 2012i?

  14. Justin D says:

    Thanks… My web management looks way different than yours.. I am bit confused how whoever set this up did it.. for example, we only have one ESX host and only one controller in the MSA. One of the iSCSI ports is going direct to ESX host.. where it get lost is the other iSCSI port is just going back to a network switch for whatever reason.. also, like I said the MSA only has one controller and two RAID5 volumes.. what is weird is the second RAID5 volume shows being on “RAID Controller B” which I assume refers to the secondary slot but that is currently empty.. lol

  15. Scott says:

    Hi Justin and Jeff-

    Any thoughts or ideas on that article mentioned above? I opened a call with VMware, but they are still trying to figure it out.



  16. Terry says:

    I am setting up an MSA2000 iscsi, connected to a blade enclosure. I am trying to figure out how to make a shared volume that any computer on our domain can access, but there doesnt seem to be a way to do this?

  17. Justin says:

    what you are talking about is a “file” share, the MSA2000 iSCSI is a block sharing device. In order to share that storage you will need to present the block device to a server, and then use software on the server to publish it to other computers. If you had something like a Netapp Filer, or EMC VNX you could present the storage directly.

  18. Terry says:

    thanks much.

  19. Terry says:

    Hi Steve.

    How is it possible to just allow one server to manage this share?, whenever I log unto any of my server 2008 server that has ISCSI initiator started its shows up in my Computer. I dont want that happening.

    Thanks In Advanced.

  20. Terry says:

    Oh Steve i have the MSA2000 iSCSI.


  21. Dennes says:

    Hi Justin,
    We use the SAS variant extensively at our clients sites, but i have been reading up on the remote snap functionality of the iSCSI variants.
    Do you have any experience with remote snap replication? If so, does it work reliably with VMware vSphere?
    Have you ever used the 10Gbit model, as IMHO the 1Gbit iSCSI variant is not an option if you’re used to the 6Bit SAS version?


  22. Len Chaney says:

    Thanks Justin.

    This was exactly what I was looking for. I just got my P2000 and am dying to get it going and finally have shared storage for our VMWare environment.


  23. emmanuel says:

    How can one change the ssh port and htttps port of the storage,
