[CentOS] Old HP Xeon server blade with only SCSI HDD ports & CentOS
Hi there. I got myself a pair of old Intel Xeon blades, which I plan to repurpose with CentOS. The model is : HP bl20p-g3 server blade Manual http://h18004.www1.hp.com/products/quickspecs/12322_ca/12322_ca.pdf Now, the main problem with this hardware is that LVD UW SCSI HDDs are hard to find and hella expensive if you find em (and of reduced capacity). Any of you know: 1. If there's any third party maker of any daughtercard offering SATA ports? The main board of the system has daughtercard sockets allowing for instance SFP ports http://en.wikipedia.org/wiki/Small_form-factor_pluggable_transceiver Seems to me that there'd be a small but interesting niche for this kind of adapter. 2. If it's possible to use BootP for booting off a network drive? I know there are some UWSCSI to SATA adapter daughtercards but those sell for $250 which is way over my budget. So, if you had one of these blades but not any UWSCSI HDDs what would you do? Thanks in advance for any pointer. This hardware is too good to back to the dumpster where I got mines from...

Hello Fernando, This drive-technology was replaced 7 years ago and the cpu's are that old as well. Better buy some 1HE Servers with an actual i3 and 500GB SATA-HDD for less than the price of an old LVD-UW-SCSI drive. With these old blades you just have excessive power-consumption, heat, low performance. We had hundreds of these old drives from storages and DMZ-servers with R1, but because of security agreements they were all shreddered. I am afraid most people that used a lot of such expensive disks have some "keep your disk" agreement and destroy them. You can always boot your system from a stick and mount your root-fs from storage. That is a standard procedure for many virtualization-setups and DMZ-proxy/fastcgi. mit freundlichen Gr??en Christian Freund ------------------------------------------- Christian Freund - freund at wrz.de -----Urspr?ngliche Nachricht----- Von: centos-bounces at centos.org [mailto:centos-bounces at centos.org] Im Auftrag von Fernando Cassia Gesendet: Freitag, 11.

As has been mentioned by several in the thread it's going to be a bit of a challenge to get it running. If the beast has 8 slots, and could draw a total max of 64A (yes, I rounded up, for a reason!) or so at -48V nominal, then each blade is going to draw roughly 8A at -48V (let's round that to -50 for easy calculations) or a max of about 400W per blade. So a 400W telco power supply is going to at most run one blade at max draw, and it could possibly run two blades with small drives. Having said that, Ultra320 drives aren't too hard to find, but since you're in .AR you might be looking at international shipping. Now, it depends on the exact model of Xeon as to whether 64 bit will work or not, and even if it does you're more likely to find that 32-bit runs better, and CentOS 5 runs better than 6. One of my main dev/test server boxes is running RHEL 6 32-bit on dual 2.8GHz Xeons of the previous generation, and it makes a fine testbed/try-this-out server. And, yes, I do know virtualization of things is the 'Way to Go These Days (TM)'. Well, unless you need a parallel port for an offbeat device controller for an astronomical instrument (IEEE-1284 CAMAC Crate, anyone? What about a SCSI CAMAC Crate (we have three)). Or you're doing other things where virtualization is simply not the right thing to do. Now, if you're in the 'experimenting' mood you might look at what it would take to adapt something like http://shop.codesrc.com/index.php?route=product/product&path=59&product_id=50 (a 50-pin narrow SCSI to SD flash card board) to LVD UW. While this box doesn't qualify as 'vintage' yet, if you want to see the lengths to which some people will go you need to go lurk a while on the vintage-computer.com forums; there are people trying to do things as 'interesting' as rebuilding an original PDP/8 (a 'straight 8') from scratch with just a collection of flip-chips, a blank wirewrap backplane, a vintage enclosure, and a set of schematics (and more time on their hands that I have!). So what you're wanting to do, if you have the time and it's more for hobby purposes (or development purposes, even), is nowhere near as far-fetched as some of the things I've been reading lately. (Long story, and way OT). Now, if I may rant just a bit. Not everyone on this list is here for professional reasons. I am; but many are not. Many people run CentOS because it's just plain fun to run it on various and sundry 'cast-off' hardware. Fernando has been around for a while; he's not a newbie. He has a new (to him) toy, and wants to make it work. Telling him 'that's too old to be useful' is useless. In my position with this not-for-profit astronomical observatory, I get this type of answer way too many times: 'You have a VAXstation 4000/90 and you need $off_the_wall_software? Why do you want that old thing? You need $insert_computer_flavor_of_the_day and our new $super_duper_alley_ooper_ka-ching_product! Forget that old stuff!' Yes, we really do have a runnable VS4000/90 (two of them, in fact), and yes it did something important (which is why the software was needed), and no it can't be replaced by something newer without multiple-tens-of-kilobucks worth of new controls hardware and more than that in software development, so can I just get my question answered, please? (Thankfully, we are building something newer thanks to crowdfunding, but it's not yet operational). (And just in case you think you might have that part, no, you don't, unless you had access to internal development information at a particular CAMAC Crate vendor who never supported SCSI CAMAC on VMS later than 5.2, and we needed to at least try to upgrade to OpenVMS 7.3 on VAX or maybe even OpenVMS 8 on Alpha (too much critical (and time-tested, certified) Fortran code to go to anything other than VMS)). Sorry for the rant.

Got two, formerly used for weather modelling. I have successfully rebuilt up to CentOS 5.9 (I haven't been able to justify the work yet to get to 5.10, but over the summer perhaps) on our 30-CPU SGI Altix 350 system, and it's running on a small 4 CPU Altix 3700 (we have another 3700 with 20 CPU's, but it has a hardware issue somewhere). RH support IA-64 in RHEL 5, so if you have an RH contract you can run straight RHEL5 on it. My newest servers are by most standards fairly old these days; a pair of Dell PE 6950's and a scattering of PE 1950's. But they're solid, and they do the job.
