Afternoon all

Is anyone at EMC doing any studies to see what impact we might expect with ScaleIO if we were to apply the patches for various platforms? I see some scare-stories warning of between 5 and 30% impact, and as I think not many people have a spare ScaleIO implementation going, it would be useful to see some results and an impact statement from the vendor.

Is this being done? And with what sort of workloads if so? Has anyone else come across any such studies? I spotted this on theregister today (Spectre and Meltdown fixes: How will they affect storage? • The Register) and it brought up some points that might relate to ScaleIO and how it would handle under these circumstances.

Jeff Ready: "I would expect SPC benchmarks (which drive pure storage performance) to be affected the most on systems which utilise software-defined storage via a mid-layer filesystem. CPU utilisation around operations on that filesystem will increase measurably. VSA-based architectures, which most companies in HCI use, fall into this category.

Personally, I'm most concerned that with a HyperV installation and VMs galore running on each node, that we may experience significant impact, so it would be good to get some stats before we begin patching.

Thanks
