AMD builds momentum in server market

The server market is fairly slow to change in all things, and that includes its processor platforms. But lately it's clear AMD's comeback is getting very real.Left for dead four years ago, AMD already has won over the gamers. Its Ryzen series of processors are the go-to choice for system builders on YouTube, whose specialty is building a high-end gaming rig in 15 minutes. But the server market is also taking note.The latest sign came from Mercury Research, which follows the semiconductor market, in particular CPU sales. For the fourth quarter of 2020, Intel held 92.9% market share to AMD's 7.1%, but Intel was down from 95.5% one year earlier in Q4 2019 and AMD was way up from 4.5%. For the server market, that's some rapid growth.To read this article in full, please click here

HPE intros SSD replacements for 10K RPM HDD server drives

There was once a time when hard drives that spun at 10,000 and 15,000 RPMs were considered fast storage. Then came the SSD and blew that all away. But there are some old servers out there still using them, and they could use a more modern approach.HPE has announced an SSD replacement option for SATA-connected disk drives in its Apollo, ProLiant and Synergy servers called Very Read-Optimized (VRO). These 2.5-inch and 3.5-inch SSDs use SATA interfaces and are plug-in replacements for the drives in the servers.HPE claimed in a Community Experts blog post this week that the drives will deliver better TCO than 10,000 RPM HDDs, although really, that's not a hard claim to make. Based on HPE's own testing, you can get 70,000 read IOPS on an HPE SATA VRO SSD compared to 400 IOPS on the fastest HPE 10K HDD. It's not even close. HPE argues that the upgrade pays for itself. It says the SSDs are up to three times more energy efficient than the 10K drives.To read this article in full, please click here

Repost: On the Importance of Line-Rate Switching of Small Packets

I made a flippant remark in a blog comment…

While it’s academically stimulating to think about forwarding small packets (and applicable to large-scale VoIP networks), most environments don’t have to deal with those. Looks like it’s such a non-issue that I couldn’t find recent data; in the good old days ~50% of the packets were 1500 byte long.

… and Minh Ha (by now a regular contributor to my blog) quickly set me straight with a lengthy comment that’s too good to be hidden somewhere at the bottom of a page. Here it is (slightly edited). Also, you might want to read other comments to the original blog post for context.
