We managed to bring the Promise VTrak demo unit online with a test cluster yesterday.
We set up a set of logical disks on the unit and configured them to connect to various cluster based VMs.
One LD was used as a data partition for an SBS v7 VM while the others were being used as the OS partition for a set of Windows 7 VMs.
Here are a couple of graphs that were imaged at the beginning of the Windows 7 Enterprise x64 OS installs:
The above shows the bandwidth being used right when we were starting.
This screenshot shows what the metrics look like over time. When all four Windows 7 desktop OSs were being installed we saw a fairly consistent 145 MB/Second to 165 MB/Second performance for the All Physical Drive Statistics (middle graph).
We have since flattened the cluster and set the VTrak back to factory defaults and are running through a fresh cluster build today.
We will then start the VTrak connection process to run through the set up steps in our in-house guide to make sure we have not made any errors.
From there we will begin testing the throughput on the VTrak via the two Intel Modular Server SCMs by running a series of OS installs and large data copies to storage located on the VTrak.
