Data centre storage performance hurt by Meltdown-Spectre patches

Mobile devices are even more vulnerable to Meltdown and Spectre than computers

Specifically, the lawsuit accuses AMD of providing a "misleading" statement; it states that AMD had allegedly supplied false statements in regards to its vulnerability to the Meltdown and Spectre CPU flaws. The company acknowledges that it still has more work to do because while the patches have mitigated the exposure to security issues, some customers have complained about frequent reboots after the update.

I'll be covering two topics in this blog post: our progress in rolling out firmware updates for the exploits, as well as addressing the reboot issue I discussed last week; and initial data from the benchmarking we are doing on data center platforms.

The Santa Clara, Calif. -based company said it would provide a beta microcode to vendors for validation in the next week.

The Spectre/ Meltdown issue is penetrating all through the computer industry as affected hardware OEMs are pushing out patches continuously, while wrongdoers attempt to take benefit out of it. Zen-based CPUs Threadripper and Ryzen from Advanced Micro Devices, Inc.

Data centre computers containing Ivy Bridge, Sandy Bridge, Skylake and Kaby Lake processors have been found to have higher-than-expected reboot rates following a recent series of patches issued to address security flaws. "We have now issued firmware updates for 90 percent of Intel CPUs introduced in the past five years", Shenoy says. The Spectre and Meltdown patches appear to degrade performance in certain workloads, as recognized by Intel, so they look for compensation now. As Intel admitted last week, some folks on Haswell and Broadwell CPUs are seeing spontaneous system restarts because of the updates.

Patching: Performance ImpactTested: Server platforms running two-socket Intel Xeon Scalable systems (code-named Skylake), which is Intel's latest server microarchitecture.

Intel confirmed that the patches are affecting performance in some cases.

And Intel said that some website servers slowed down by 2 percent as a result of the patch.

Intel says that it's trying to also identify workarounds for performance problems. In addition, Intel is moving to get Retpoline, a security approach discovered by Google that helps address part of the Spectre vulnerability, and which is short for "return trampoline", into place.
