Is the maximum number of SCSI target that ESX Server can maintain 80?

I connected ESX Server and EqualLogic PS100E by software iSCSI. I exported 256 LUN for ESX Server from PS100E. 256 LUN is a displayed in a /var/lib/iscsi/vmkbindings, but it is displayed only 80 LUN by VI Client.

Can it be displayed to 256 LUN if you change some setting?

\# The number of the targets rises when they add LUN with specifications of PS100E.

\# For example, the first LUN is displayed as vmhba40:0:0, and the second LUN is displayed as vmhba40:1:0.

That's really interesting. ESX supports 256 LUNs and 1024 paths, depending on how many NICs you have bound to the iSCSI network you could have too many paths for ESX to handle. What output do you get from esxcfg-mpath --list?

IIRC, a PS100E isn't a very large storage array, are you just testing the limits of ESX, or do you really need more than 80 LUNs on the iSCSI array?

Thank you for comment, dominic7.

A result of "esxcfg-mpath --list" is as follows.

As you say, PS100E isn't a very large storage array. I use PS100E as a test, but I intend to use more large storage array(PS300E) if this test goes well. So I need more than 80 LUNs on the iSCSI array.

The PS300E is 7TB RAW, why would you need more than 80 LUNS on it? Why would you need LUNs smaller than 90G each?

Hi, dominic7.

I am going to assemble VDI. So, I want to operate 400 Virtual Machines. I think that 20GB is enough for one Virtual Machine.

You may only want 20GiB per VM, but you certainly don't need to have 1 VM per LUN. You should be able to easily put 12-15 VM's on a LUN of about 250-300GiB in size.

Hi, tsherbak.

Thanks for the input.

When the upper limit value of targets was to 64, it was written in the following document.

Hi, dominic7.

Thank you for a quick reply.

Though I can put 12-15 VM's on a LUN of about 250-300GiB in size, does not a performance of Virtual Machines deteriorate?

12-15 VMs ( actually .vmdk files ) per LUN is the "sweet spot" for LUN performance. It depends on the I/O on the VMs, but generally you won't see performance degradation until you exceed 15 .vmdks on "typical" workloads.

Thank you for useful information.

I will test with 12-15 VMs per LUN.

Thank you.
