It’s been a crazy couple days on a couple fronts, but the most material front has certainly been Spectre and Meltdown.
There are lots of sources, and the trick is that while distinctly the root cause lies in the CPU domain and with the CPU manufacturers- the impact touches nearly everything.
It’s been keeping the team here busy for a while.
For Dell customers – here’s the main place for aggregation of the latest official information and updates – for everything from clients, storage, network, data protection, and CI/HCI. This page also links to key partner ecosystem official landing pages.
One that I want to call out specifically – VMware customers have some benefits naturally, but updates are still critical, and you can read more on that here.
Yes CI and HCI customers there will be formal system level updates (and they will be on that page) including RCM updates for VxBlock and VxRack FLEX, as well as automated updates for VxRail and VxRack SDDC. We’re aggregating up all the impact assessment and rolling everything into a common update.
For those seeking to understand what this is all about, I would start:
- Here if you want “just the facts” and are of a comp-sci bent – the Project Zero blog from Google is pretty authoritative on the root cause and how the exploits work (though it was discovered by several groups nearly simultaneously)
- Here if you want the summary, with some added commentary/snark (in classic El Reg style).
A little bit of personal perspective:
- IMHO, this falls into the “failure of imagination” error category – like the fire in Apollo 1. It’s so obvious now how speculative execution could be exploited, but it’s a facepalm moment. My 2 cents – witch-hunts don’t help, learning does. We will pick ourselves up, learn, and get better from the failure.
- I know it’s hard – but try to pragmatically work the problem, not guess. Since the cause is with the CPUs, but the impact is industry wide, lean on your partner ecosystem to help you (certainly not limited to Dell Technologies, there’s a lot coming from Intel, ARM, AMD, Microsoft, Google, Apple and others)
To continue the space program metaphor, and to quote the one and only Gene Krantz: “Let’s work the problem people. Let’s not make things worse by guessing.”
It’s only logical that the fixes and workarounds for these 3 exploits will have some degree of performance impact (since they are fixing/working around a flaw in something that is a performance optimization, namely speculative execution). But – the impact will vary. I’ve seen people latch on to early data, or data from one workload or another, or one test that they read online somewhere. Let’s not panic, let’s pragmatically work the problem together.
Welcome to 2018!
