I’ve been using the Dell CS24-SC servers at work now for about two years, so I figured I’d post about them. While they are Dell-branded systems, they are manufactured for Dell by Quanta. Most of them were manufactured for Facebook. The most common hardware configuration we’ve seen is a Dual Xeon L5420 with 16GB RAM.
The BIOS and BMC firmware that comes on most of these systems are horribly outdated. There are a few BIOS and BMC firmware versions floating around, but the most stable ones I’ve found are BIOS 3A25 and BMC version 2.50. They are available on robwillis.info.
The systems perform very well and are reasonable on power usage compared to other servers utilizing these CPUs, thanks to the DDR2 ECC PC2-5300P Registered RAM modules. These RAM modules use a fraction of the power that Fully Buffered DIMMs use, which was the most common RAM used on the Xeon 5400 series. The CS24-SC is limited to a maximum of 24GB RAM using 4GB modules. The RAM is also available very inexpensively on the used market.
They run all modern operating systems with no issues that we’ve run into so far.
Based on performance per dollar, these systems are a great value, even though they are as much as 7 years old now.
ICANN has terminated RegisterFly’s Registrar Accreditation. After all of the recent controversy surrounding RegisterFly, I’m not surprised. It will be interesting to see what happens now — it sounds like RegisterFly may be forced to transfer customer domains in bulk to another registrar. If that happens, will RegisterFly get any kind of compensation? Watching this story play out could prove to be very interesting.
Red Hat Enterprise Linux version 5, at long last, was released today. This release is based roughly on Fedora Core 6, which is a huge update from RHEL v4 (which was based off of FC3). I look forward to installing CentOS 5 when it is released in about two weeks.
One other thing worth noting — The Fedora Project recently started Extra Packages for Enterprise Linux (EPEL) which looks to add a new repository for RHEL/CentOS/etc users who are looking for packages that are not included with RHEL but are available in Fedora. This will bridge a gap between Fedora and RHEL.
Good job, Red Hat!
I just upgraded WordPress because I was suddenly getting thousands of comment spam that seemed to be coming as a result of some kind of bug in WordPress. Hopefully the madness will stop now.
Well, I’ve not really spent any time on this site recently, but I’ll try to come back soon. I’ve been pretty busy with a number of things, but I’m sure my superior procrastination abilities will bring me back.
I’ll try to update soon. The recent Brand-X and Grokster decisions by the Supreme Court were surprising. More soon.
I made the switch to WordPress this evening, after thinking about making the switch for a while. We’ll see how things go, but I definitely like it better so far. Thanks to Chris — I used the tips he mentioned about his conversion so I could import all of my old posts.
I’ll probably be playing around a bit with the formatting and theme stuff over the next few days. We’ll see.
UPDATE: Apparently, any links I had in the title bar of the posts from b2evolution are gone now. Also, I can’t setup the Permalinks like I want to because it didn’t import the post titles correctly. ::sigh::
So, basically, there’s a lot broken. I’ll work on fixing it, but there’s 100 posts to comb through, and I tend to get lazy quickly. I’ll work on it eventually.
