After upgrade 4.1 to 5, no "iscsi software adapter" showing up??

Hi,
We have several hosts running esxi 4.1.  I installed 5.0 to a USB drive on a computer, and then plugged that USB flash drive into the host and restarted booting from the flash drive.  5.0 loaded up fine, the local datastore automatically showed up, and i re-added the VMX files to inventory, and powered machines up - no problem.

I am having an issue, however, with iSCSI.  We use an iSCSI NAS device (iomega) for Veeam to send replicas to.  In the past we've always set it up with "iSCSI storage adapter", under the Storage Adapters in Configuration.

After the upgrade to 5.0, there is no such option.  In the end I was able to get the iSCSI target set up using one of the "Broadcom iSCSI adapters", and assigning one of them to a vmnic, etc. but it's still worrying - why does "iSCSI Storage Adapter" not show up on 5.0!?

We use local storage for all VMs running on this and our other hosts

Any ideas?  If i'm not doing something right, let me know.  If somone could explain what the Broadcom iSCSI Adapters that show up on both 4.1 and 5.0 are for, that would be great.  That's what i'm using right now, and it's working, but not sure if it's the best way to do it.

Attaching a picture of the adapter showing up in our 4.1 host, but not showing up in our 5.0 host.

Just Click Add in Software Adapters, now read on....

VMware decided in ESXi 5.x, you need to ADD (ENABLE) the iSCSI Software Adapter. In 4.x, you just needed to Enable the Adapter, it was already installed.

So have you ADDED the iSCSI Software Adapter? See Step 2 and Step 3 in my Article, it's not visible, until you Add it! (under Storage Adapters)

See my EE Article

HOW TO: Add an iSCSI Software Adaptor and Create an iSCSI Multipath Network in VMware vSphere Hypervisor ESXi 5.0

The VMware iSCSI Software Adapter is a software adapter (software emulation), you have 4 x hardware HBAs in your server also.

The Dell R710, the four integrated motherboard Broadcom networks, are dual nics/hardware iSCSI HBAs.

Under certain conditions, hardware iSCSI HBAs can perform better than the software HBA, but in our tests we've found that software iSCSI HBA and Jumbo Frames out performs the hardware HBAs (because they do not support jumbo frames).
