Raptor Versus Seagate SATA-II

Apr 28, 2008

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.

SATA 7k RAID 1 Vs. 2xSATA 10k Vs. SATA+SAS

Jul 3, 2008

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?

How Do I Know - Seagate 73GB 10K RPM Or 15K RPM SCSI HDD

Aug 30, 2008

Is there a way that I can check if the host provider installed the correct hardware for my server?

I had 3x Seagate 73GB 15k RPM SCSI so I wonder if there is a way to confirm that make sure they gave me the 15k but not 10k?

Western Digital Or Seagate

Dec 23, 2007

We have been using primarily Western Digital drives in all of our server (Raid Edition Series "YS) but have had some problems recently with failing drives, or SMART errors on drives that were only a month or two old. I'm beginning to think maybe Seagate is a better choice?

Based on all of the experience out there, which way do most of you lean...WD or Seagate?

Seagate OEM Drives... SUN Firmware

Jun 29, 2007

So I bought 4 little simple SCSI drives to build up an older dual p3 server... and they worked great.

Later I bought 4 more and was going to build up an identical machine... but I ended up sitting on it for a few months.

Now that I've gone back to it... I've discovered that the more recent 4 drives have a SUN firmware on them... and CentOS doesn't know how to install on them.

ST318404LC

I've managed to download SeaTools Linux CLI and other tools for downloading (uploading) a firmware file to the drives.

However, I can't figure out a way to copy the existing flash on the working drives to a file, or I can't find a firmware update for the drives

Am I Really On A SATA

Mar 28, 2009

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

SSD Vs SCSI Vs SATA

Jun 11, 2009

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.

1 SCSI Vs 2 SATA

Dec 28, 2007

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 .

SCSI To SATA Adapter

Sep 2, 2009

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.

Installing Xen On CentOS With SATA

Feb 16, 2008

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.

SCSI, SAS Vs SATA II Reliability

Apr 11, 2008

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.

Boot From A PCI SATA Card

Feb 4, 2007

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.

Nearline Sata Drive Performance

Oct 28, 2009

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?

SATA Drive Issues On DG35EC

Oct 23, 2009

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.

but i think those thread are too old,

and by the time pass and technology growth,

it may take difference,too.

in my feeling,i like seaget,

but some people tell me WD may be better,

if possible,could you tell me your choose or experience?

for possible,it can include the series type,

for example,WD 500G WD5000AACS...etc.

Cost Effective SATA Array

Jul 6, 2007

Can anyone recommend a good case/enclosure for a sata raid array? I would like to build an array using 500 GB SATA Harddrives. Will the server need much processing power and ram if I am going to use a decent hardware raid card? What card would you recommend? Are there any premade sata arrays that allow you to just pop in your own harddrives and don't cost thousands of dollars?

Also, can anyone recommend a enclosure if you had a server that had build in raid with 8 sata ports, but only two harddrive bays and wanted to use the entire 8 ports?

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.
