    Login VSI results for HPE SimpliVity 325

    Congratulations to HPE SimpliVity for another successful validated by Login VSI achievement!

    This latest hyperconverged (HCI) result is based on the HPE SimpliVity 325 platform leveraging 2nd Gen AMD EPYC processors.

    This validation confirms that a single, tiny, little, 1U HPE SimpliVity 325 server demonstrates high performance for 300 Knowledge Workers per server. This is nearly double the standard scaling rate for servers running VDI workloads, and I am so excited to see performance numbers like these. The validation also confirmed linear scaling, at 300 desktops per server, up to six systems in 6U providing high performance for 1800 Knowledge Workers. Think about that…you could almost fill a room with 1800 laptops, and this solution fits in 6U or 10.5 inches of rack space. Very impressive.

    The configuration for this test is a six-node HPE SimpliVity 325 Gen10 hyperconverged infrastructure host deployment to support 300 users per server host and six of the same nodes to support 1800 users. The six-node environment was deployed as a 6+0 cluster. Each 1U host having one 2nd Gen AMD EPYC processor and 1 TB of memory.

    About the Login VSI Performance Numbers

    Let’s look at the performance results from this validation. With so much compute and memory power in this little package, it’s no surprise that they didn’t hit VSImax (and SimpliVity hasn’t in past Validated reference architectures). This is common with solutions in the HCI category, but let’s look at a couple of different Login VSI metrics—VSIbase and VSImax Average (VSIavg). For this validation, the VSIbase for the 6-node, 1800 session configuration is 631ms. From the table and chart below, they didn’t hit VSImax of 1631ms even with 1800 sessions. Impressive results for six, small 1u HCI servers. Another reference I like to compare is the difference between the baseline and the ending VSIavg. Below you’ll note that their VSIavg at 1800 sessions is 1431ms, and the baseline is 631ms. That means each user only experienced a change in responsiveness of less than a second (only 800ms) with the system completely full. Again, very impressive.

    *VSIavg 1800 is based on 1798 session value.
