The recent revelations about the Spectre and Meltdown vulnerabilities found in Intel CPUs have had far-reaching consequences. Being in the storage industry, we've been most interested in the impact that these vulnerabilities (and their fixes) have on storage.
Here's a roundup of some of the best information we've found:
The Register's interview with Jeff Ready of Scale Computing: Ready talks about what the performance impact could be for storage benchmarks (like SPC), and why, both for his own company's systems and others.
The Register's discussion with Dell and Pure Storage: This interview discusses whether hardware- or software-based storage is more or less likely to be impacted.
William Lam's blog post: He offers a powercli script that identifies which components in your VMware environment need patching. He also has some follow-up posts that can automate remediation.
Tech Republic covers the major vendors: A review of Dell EMC, IBM, Hewlett Packard Enterprise, NetApp, and Vantara, with responses from each vendor on what to expect, and what they are still investigating.
Chris Evans' blog post on different storage architectures: This is probably the most comprehensive and thoughtful review of the situation that goes beyond vendor responses, and really talks about the technology and expected results.
Andrea Mauro's collection of blog posts: These posts range in topics from backup products to specific vendors to the landscape in general. (Also available in Italian.)
