Support is generally good and they even have a repository for Linux. Since i'm in charge, we don't buy Dell anymore for various reason: 1) They costs more than server barebone and in our case, we don't really need to pay a premium for a service we don't need. I prefer to have a couple of spare servers that i can do tests while not in production 2) Dell, as the others VARs, uses a lot of non standard hardware parts. So if you want to replace let's say a mainboard (when out of warranty), you'll have to pay a premium to get it. 3) Right now, we have about 5 Dell PowerEdge 2550 and they are not supported anymore by Dell (i know, it's old!). They don't have the admin tools for CentOS (and Upstream) and i think it's the same for other distributions. So support is good for the first years, after a while, they seem to drop it. So now, we buy Tyan barebone. The last batch was 2U Tyan Transport TA-26 (B3992-E). This model use a Broadcom Serverworks chipset, support Registered ECC DDR2 RAM up to 64 Gigs and has 2 sockets F for Opteron CPU. CentOS works great right out of the box (we use Adaptec 3405 or 3805 SAS/SATA controllers). The mainboard is standard E-ATX and can be upgraded or put on another machine. This model has 8 SAS/SATA hot swap backplane. The only downside is that sometimes, it takes time to get them. It's like Tyan has problem producing enough for market demand. I have a couple of other servers that i built with Antec rackmount chassis and the same mainboard. My advice: Go with VARs if you have special requirements and/or want premium service. Go with server barebones if you have access to hardware competent tech people inside your company. As for Intel or AMD for CPU, i buy 90% AMD because if they don't survive, just watch the prices skyrocket as Intel would be alone. AMD is selling at competitive price so no hurt here. The new line of low power Opteron are great IMHO. As a last note, i don't have any affiliation with Tyan and i think you could get comparable hardware from SuperMicro and the likes. Choose your hardware for Linux, not the opposite! Hope this helped a bit. Guy Boisvert, ing. IngTegration inc.
