After the recent patches to AWS for Spectre and Meltdown vulnerabilities, SolarWinds documents some of the substantial impacts on the public cloud provider. While CPUs were hit hard, perhaps the most important impact was on overall latency.
In the fallout of the Meltdown and Spectre flaw disclosures, we’re beginning to see various tools role out updates to help alert admins to needed patches. Runecast Analyzer is the latest to offer such insights.
We’ve seen OS and chipmakers respond to the Meltdown and Spectre flaws with patches since the rampant speculation last week. What remains unanswered is how these patches will specifically impact performance on storage arrays and HCI systems. Chris Evans runs down what we do know, and some of the initial company responses.
Howard Marks is writing a series on hard drive evolution. This looks back to times when storage media was removable, 14-inch disks were a thing, and drive controllers existed off disk. While spinning media may be losing mind share to SSDs these days, Howard gives the historical context to show just how much engineering has gone into the modern hard drive.
Chris Evans has some interesting thoughts on where cloud adoption is going. He stages for cloud adoption go from initial private cloud implementations to something he calls a “multi-cloud brokerage”. There’s no doubt that in 2017 we saw multi-cloud strategies become common talking points for any number of vendors. While fear of cloud lock-in is perhaps overblown, multi-cloud seems to be where many organizations want to go.
Iperf is a well established tool for network diagnostics and performance information. In this piece Brent Salisbury gives a tutorial on how to use the tool with Docker. This lets network admins easily setup containers, run server-side and client-side tests, and destroy the containers in a few simple steps. While many out there may be […]
Winter seems to bring out the worst Intel processor bugs. Last year it was Atom CPUs causing devices to brick. This year it’s something even more serious.
An interesting piece of marketing from Qumulo got me thinking, what would a ground up enterprise file system in 2018 look like?
Mechanical hard drives are fighting a losing war against flash in most markets. That doesn’t diminish the fact that they are marvels of engineering. The precision needed to add increasing density and platters is truly a remarkable feat of technology. Seagate just upped the technical “wow” quotient by announcing upcoming drives with multiple independent actuators.
