Is SA-SCSI 10K RPM Is Far Away Better Than Raptor SATA 10K
Oct 26, 2008I'm going to use it for a massive SQL database driven site.
Was wondering if SA-SCSI 10K RPM is far away better than Raptor SATA 10K if combined with quad core processor and 8GB RAM?
Raptor Versus Seagate SATA-II
Apr 28, 2008How 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.
View 8 Replies View RelatedNearline Sata Drive Performance
Oct 28, 2009We 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, 2009I'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.
Drive Setup For VBulletin - 4 X SAS Vs SSD Vs Sata Raid-1
Apr 5, 2009For a Vbulletin forum with up to 200 users online (only) but growing nicely and I want to be set for quite a while:
I am going to use Nginx, XCache, PHP-FPM, FreeBSD, Gzip
Currently using ~55 GB transfer with mod_deflate, all with dynamic traffic, little bits and pieces, no bigger files.
I want to be able to push 500 GB transfer or so this way, or ~ 1000 users online, many searches from non-registered users, too
I am looking at
Q9550, 8GB, 4x73 SAS 10k Raid-10, $200 Webnx
or
i7 920, 12GB, 4x73 SAS 15k Raid-10, $250 Webnx
or
X3220, 8GB, X25-E SSD Intel, $300 Softlayer
Am I too concerned about disk I/O? Should I save some money and settle for a 2xSATA Raid-1.
Databases are < 2GB and would fit into the RAM
GRUB Error 21 / Booting From 2nd SATA Drive
Apr 26, 2007I just got a new server with two SATA drives in it (no hardware raid). Both drives work fine under Linux, BUT I can boot only from the first disk.
The system is Debian Stable, boot loader is GRUB. I've got serial console access, so after power on I can see GRUB menu and escape to the shell. Then:
Code:
grub> root (hd1,1)
Error 21: Selected disk does not exist
Even when I type "root (hd" and press TAB, grub auto-completes command to "root (hd0,". It doesn't see the second drive!
When Linux has started and I run grub shell inside OS, it does see (hd1).
250 GB SATA With RAID-10 Or 300GB 15k Single SCSI Drive
Dec 11, 2007Planning to buy a server from softlayer, adding a single 300gb 15k scsi drive costs 100$/month and adding 4 250gb sata drives with raid-10 costs 90$/month

SATA 7k RAID 1 Vs. 2xSATA 10k Vs. SATA+SAS
Jul 3, 2008I'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?
Database Server - SCSI/Raptor
Jan 29, 2008I'm about to purchase a 2nd server to use as a database server. I've been quoted for 2 x SATA II 320GB hdd's in RAID 1 (the same of which I currently use on my single server), but searching around it appears SCSI is the norm for db servers. The problem is, my host does not offer these as a standard/upgrade option and they would need to be specially ordered (along with RAID card), which is expensive.
The fastest disks they offer are 150GB SATA 10K Raptors. My question is, would these be sufficient (compared to SCSI) and do they perform noticeably better than the standard SATA II disks?
Quoted database server specs:
Server = 1 x Dual Core Intel Woodcrest 5130
Memory = 4G RAM
Hard Drive 1 = 320G SATA II Hard Drive
Hard Drive 2 = 320G SATA II Hard Drive
Raid Config = RAID 1 (3 Ware Hardware RAID)
Bandwidth = 3000G Multi-Homed Bandwidth
IP Address = 4 IPs
OS = Centos 4.6 32 bit
Service Monitoring = Ping Monitoring with Email Notification
Server Management = Self-Managed
Control Panel = None

Raptor Corrupted In First Month Of LSN Server
Sep 12, 2008My 150gb Raptor drive in my Q9300 + 8gb ram server got corrupt. When restarting, the tech got a halt error:
Windows failed to load because the kernel debugger DLL is missing, or corrupt.
Status: 0xc00000e9
File: Windowssystem32kdcom.dll
Their tech support is good, but I've lost all my valuable data. I can't say that I'm happy about using Limestonenetworks now. I never suspected that I'd be having a disk failure in the first month.
Data Lost , But Still Have Old Home Drive , How To Copy To New Drive
Jan 26, 20071- i did Os Reload with new Hard drive for "home"
2- data "backups" drive lost
3- replaced the old home drive as "/old drive"
4- " /old drive " is now the secondry drive in my server and it has the all sites usres and evry thing
5- what i need , to trasfer, copy this sites from " /old drive " to "home"
but data center said
The /olddrive/home directory contains the contents that were previously in the /home directory. You can copy files from this directory to any other directory on your server.
The command to copy files in the UNIX environment is the "cp" command.
The user directories in /olddrive/home directory contain the web page files for the users. However, simply copying the contents over will not recreate the users or domain entries in DNS/httpd. If you wish these back you will need to recreate them manually or restore them from backups.
Drive Corrupt, Recovery From 2nd Drive Mount
Feb 16, 2007Primary drive (centos/cpanel) is corrupt
The server is displaying these errors when I tried to do an FSCK:
Bad inode IO
ext3-fs error (device(8,3)) IO Failure
I am having a new primary installed and old primary set as 2nd drive. I need to recover the cpanel domain accounts from this 2nd drive after I mount it with the method below:
mkdir /backup
mount /dev/sdb1 /backup
However, how do I actually recover these accounts in an automated process via whm? I've done this before with the same matter (corrupt primary drive, mount as 2nd, etc) but cannot exactly remember the proper steps.
How To Copy My Current Drive Contents To A New Drive
Dec 28, 2007I just purchased a brand new 10K 150GB drive. How can I take an exact copy of my current drive and transfer everything over to the new drive? I think I need to create a snapshop, or mirror it somehow.
What software will do this? I was told trueimage, but its very pricy, is there anything else?
Drive Corrupt - Should I Ask For New Drive Or Reimage
Jul 9, 2007I have a dedicated box and I started getting Input/output errors today.
I tried:
# fsck
fsck 1.40-WIP (14-Nov-2006)
e2fsck 1.40-WIP (14-Nov-2006)
/dev/hda2: recovering journal
fsck.ext3: unable to set superblock flags on /dev/hda2
then I tried:
# fsck -a -t ext3 /dev/hda2
fsck 1.40-WIP (14-Nov-2006)
/dev/hda2: recovering journal
fsck.ext3: unable to set superblock flags on /dev/hda2
My data is backed up, so was going to ask for a reimage, but is this an indication of bad hardware? Should I ask for a replacement drive? Is there anything else I should try on my own before going to the host?
Mirror Drive A > Drive B
Feb 6, 2007I have a Win2K3 server which has 2 hard drives. I was considering backup options and I thought that I might try mirroring Drive A ==> Drive B. I would think that, then, if Drive A has a hardware failure, I could simply switch Drive B into the Primary slot (A) and the server would continue to hum along as nothing has happened. This would reduce the downtime, hopefully.
I have 3 questions.
1. Is this idea practical (will it work)?
2. What is a good software program to use fto handle the mirroring?
3. Any considerations, warnings, technical advice in regard to this method?
Am I Really On A SATA
Mar 28, 2009I 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

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

1 SCSI Vs 2 SATA
Dec 28, 2007I 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 .

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, 2008I'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, 2008is 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.
