SATA Cables - SC512L-260B
Oct 7, 2007
We just got in our first shipment of Supermicro SC512L-260B cases. We have been using much larger and more expensive 1u (or even 2U) cases, even for base servers. I wish we had went with this chassis a long time ago.
My question is on the SATA cables. I know you can order the Supermicro CBL-0044 cable to allow connection to the hard drives in tight spaces, but these can be expensive or hard to find. I have a few coming, but does anyone have a source or know of a generic cable that will work? Or how do those of you that use this chassis route standard SATA cables? I see you might be able to go under the fan, but I'm not sure that is a good idea.

Is there a current motherboard out there that will fit the Supermicro SC512L-260B chassis without modification? I think Foxconn had one recently, but it may have been discontinued.
I know sometimes you have to grind off the the Audio since it is too high for the 1U chassis. I'm hoping maybe ASUS has something that will fit.

some cables for the SuperMicro SC512L-260 case. I believe these are the correct part numbers:
CBL-0084L - Converter cable for front panel connector for non-SuperMicro motherboards
CBL-0044L - Serial ATA Cable that is compatible for use with limited space to plug into hard drives
We'd also be open to a different Serial ATA cable that would work with the case.
We're having trouble finding these in Atlanta. We'd prefer to either pick them up tomorrow, or buy them today and have them overnighted to us in Atlanta.

about the hd,there are two options, the first one is four 7200rpm sata to do raid 10,
the second one is two 10000rpm sata to do raid 1, about the performance, which one will be better?

what does the bracket do? do i need rails for colo or can the server be mounted on the rack and where do i get the rails for it?
edit: i just read the comment by one buyer.
"Pros: No expenssive rackmount rails required, mounts using the intergrated ears, very good airflow for such small case. Very well built, pretty solid for price range. "
so no rails is required...by intergerated ears i assume he mean the two handle on each side and the bracket can be use to mount the server. how strong are they? Can they really hold the server?

I'm currently in the process of ordering a new server and would like to throw another $50-$70 at the default SATA II 7k 250 GB to increase performance. The server will host a site similar to WHT (php, mysql, and some forum traffic ).
There are three options I can get for the price:
1. Add another SATA II 7k 250 GB and set up RAID 1
2. Add a 73GB 15k RPM SA-SCSI and put mySQL on it. No RAID.
3. Toss out the SATA II 7k and take two SATA 10k 150 GB instead. Put mySQL on one of them. No RAID.
Please keep in mind that the question is budget-related (I know I can get more if I spend an extra $200 but that's not what I want ). Which of the above will make me happiest?

I'm pricing out various options for KVM over IP solutions, and noticing that most of the options (Raritan, Avocent, Minicom, etc.) have RJ45 on the back, terminating in VGA+PS/2 or VGA+USB.
Minicom's version of the cables costs about $75, whereas the Raritan ones are about $150/each. Does anyone know if cables from one brand will work with another? It seems that there's no reason they wouldn't, but I also wouldn't be all that surprised if they swapped pin arrangement or the like just to make you buy their cables.
Has anyone done this before? Specifically Minicom adapters on a Raritan or Avocent KVM unit (RJ45).

I'm searching for a UK supplier of quality (consistently up to CAT5e spec) stranded patch leads. I'll be buying in semi-bulk quantities; I'd estimate 5-10 of each cable, 50-100 in total.
They should be available in at least 0.5m, 1m, 2m and 3m lengths; longer lengths are unneeded. Ideally, they would be available in 10cm increments. Availability of multiple colors is important.
I'm also searching for 24/1U 48/1-2U CAT5e through coupler panels.
[remove spaces in links - the forum doesn't seem to like me even writing URLs] tinyurl.com / 2xdyn2h (unfortunately, I am not allowed to link to them) and tinyurl.com / yw29ch appear to be good. Comments on them would be appreciated.
Cablemonkeys through couplers are, IMO, very expensive for what you get - Mini5 are reasonable. What difference can you see between them? Cablemonkeys do appear to have better cable management.
I've heard of problems with mixing cable and patch panels from different manafacturers, though mostly with CAT6; would this apply with through-couplers?

Has anyone been using a 1333 FSB Core 2 Duo board in the SC512L that will fit without modification? Looking for something for mass use, I know some of the server boards will fit fine, wondering about some of the ASUS or Foxconn boards.

I rented a new server. I check WD6400AAKS, it's indeed a SATA drive. However, why is the label says hda and hdc? Isn't it supposed to be sda and sdc?
Is it true DMA is not needed for my SATA?
Is my disk performance to slow? Does the performance suggest it's a IDE disk?
Here is what on my WHM
hda: WDC WD6400AAKS-65A7B0, ATA DISK drive
hdc: WDC WD6400AAKS-65A7B0, ATA DISK drive
hda: max request size: 512KiB
hda: 1250263728 sectors (640135 MB) w/16384KiB Cache, CHS=65535/255/63
hda: cache flushes supported
hdc: max request size: 512KiB
hdc: 1250263728 sectors (640135 MB) w/16384KiB Cache, CHS=65535/255/63
hdc: cache flushes supported
root@abc [~]# hdparm /dev/hda
/dev/hda:
multcount = 16 (on)
IO_support = 1 (32-bit)
unmaskirq = 1 (on)
using_dma = 0 (off)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
geometry = 65535/255/63, sectors = 1250263728, start = 0
root@abc [~]# hdparm -Tt /dev/hda
/dev/hda:
Timing cached reads: 12040 MB in 1.99 seconds = 6036.46 MB/sec
Timing buffered disk reads: 24 MB in 3.20 seconds = 7.49 MB/sec

about SSD vs SCSI vs SATA HDDs?
I heard that SSD are slow in writing, but fast in reading.
is this true?
80GB Intel X25-M SSD is the model i am looking at.
Is this HDD recommended on servers? will this perform better then SCSI or SATA RAID10?
how this works, tell me more about writing
eading speeds (on SSD) etc.

I currently have a Dell Poweredge 2650 from a few years back, it is running...
2x Xeon 2.4ghz 512K
3GB DDR266 RAM
1x73GB SCSI
Back in the day this system cost $2000, now it's not worth close to that.
So my plans were to dump this bad boy as an SQL server, seeing it has the SCSI backplane and 3GB of RAM, and SQL usually doesn't need as much CPU as a web server.
Now my question, would it be better to use this server or would it be better to build a cheap Core 2 Duo with a RAID0 array with a few SATA drives?
Before you start going off on RAID0, it doesn't matter to me because I am using clustering/failover so data will not be lost and no downtime will be received if the array fails.
Basically what I want to know, is it worth it to keep this server and build upon it or would it be better to sell this server and look into spending an extra few hundred to build a new system with SATA RAID.
I'm going by price/performance rather than reliability as I am using failover to let you know once again .

I am looking for something like this:
[url]
To work on an HP ProLiant DL360/380. All I know is they are SCSI U320 drive bays, or that is the type of drive they take. Can anyone provide any insight on what may work? We are trying to get a more cost effective way to get more storage into a server. The largest SCSI drive I can find is 300GB for $200. You can get 2TB drives for that much these days.

I've got a 'virgin' machine from Nocster running CentOS 5, including a SATA drive (shows up as "SCSI").
It looks like it'll be a straight-forward install [url], but I wondered if anyone has had this exact combination before and if there are any problems I should expect? Given that it's a dedicated machine I don't have physical access to, I'm slightly paranoid about screwing up.

is it really worth the money nowadays to put in SCSI or SAS instead of SATAII (single disk, non-raid here), IF reliability is the only concern (i.e. NOT i/o performance) during the usual 3 year life time of a server?
Actually, I was pretty amazed by the sata reliability, in the past 3 years the only hdd failure was two sata on a mismatched mobo, which didn't support SATAII (a lot of read/write error, eventually died). Although we have 0% scsi and sas failure.

on a new pc I tested to install a new disk sata;
ok I installed with using application disk manager 10, but when turned on pc I not see the initial dos screen;
I see directly win xp; (one other pc I have a first step where see for 1 second the dos and where I can, if I want, enter in the bios);
in this new pc I not see this step, so I not know how enter in the bios;
I clicked F10 etc other buttons but not work;
at the moment , after I does some error with acronis for make a dual bootI have this error:
pc not turn on more win xp but have always error mbr;
if I insert a boot floppy I can see the prompt C:
but if I write dir I not see noone files
I have only the dimension of the disk;
if I write format c: not work;
QUESTION:
how I can format all and reinstall
better the sata disk?
and after, the steps for install on a 2nd partition one linux S.O.

I have an old server with only IDE and SCSI connectors on the mobo.
However, I have only SATA drives and no IDE available. I consider to buy an entry level PCI SATA adapter card. What do you think ? Can I install and boot Linux directly from it?
There is no raid involved.

We have had some old dell 745n that had sata drives in them in the past. These are the only time we have ever used sata. The performance was terrible and we replaced the sata drives more times in over several years and we ever have with sas/scsi drives.
We are looking to get some new disk backup boxes which we plan to go 600gb sas drives, but might be considering 1tb nearline sata from dell.
I would like to hear from anyone using nearline sata and get feedback on performance and reliability overall. Also if you are using for backups, how many backup jobs are you able to run at the same time before performance drops?

I'm having the same problem that a lot of you also faced - my SATA disk is being detected as an IDE disk. (/dev/hda)
I've had the datacenter set AHCI mode in BIOS, however that didn't seem to fix the issue.
I keep hearing about kernel upgrades fixing this problem, would it really help?
Or is there any other way to go about fixing this without having to reload the OS?
I'm running CentOS 5.4 x64 on the 2.6.18-164.el5 kernel.

How much faster is a Raptor 74GB 10,000rpm compared to a Seagate 250GB SATA-II 7200rpm? Both are priced the same. I'm comtemplating on which one to use for a database..go for more storage or a faster drive.
