Disks For VPS - SATA Or SCSI
Oct 2, 2007For building a house for, ie, 30 VPS, what kind of disks are you using? normal SATA? Raptor? SCSI?
I am going to use Quad-core CPU with 4-8GB RAM, but still wondering about the disks

Jun 11, 2009about 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.

Any experience?
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 .
SCSI To SATA Adapter
Sep 2, 2009I 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.
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?
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.
147GB SA-SCSI 15K RPM Or Free 250 GB SATA II
Aug 11, 2008Is it worth to pay $75 for 147GB SA-SCSI 15K RPM rethar than free 250GB SATA II?
I mean is it very big differance in speed?
Can clients feel that?

Server With SCSI And SATA Hard Driver
Apr 17, 2008Within 2 servers below, what is faster than:
Server 1:
Primary hard driver: 73GB SCSI 10k (for system, database...)
Secondary hard driver: 160GB SATA (for /home/ directory)
Server 2: 2 x 160GB SATA RAID 1
SCSI Vs SATA For Web Server Running Only Php Scripts
Sep 11, 2008Would having a 15k rpm SCSI HD (vs 7200rpm SATA) provide significant improvement for a web server only running php scripts (the scripts are small in size, they just make DB calls to another server and return the results)? What if eAccelerator was installed?

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
Which one would you pick up and why?
Whats The Best For Server With SATA Raid 1 And SCSI Raid 10
Jan 14, 2008So I've just got a server with 2xSATA raid 1 (OS, cpanel and everything in here) and 4xSCSI raid 10 (clean).
Which one do you guys think will give the best performance:
1. Move mysql only to 4xSCSI raid 10
2. Move mysql and home folder to 4xSCSI raid 10
Raid 1 SCSI Or Raid 10 SATA 10k
May 23, 2007Just curious what your thoughts are on performance:
2 SCSI Drives 10k w/RAID 1
or
4 SATA 10k w/RAID 10
Prices are not too different with 4 drives just being a tad more.
7200 Rpm Sata With Raid 10 Vs 10000 Rpm Sata With Raid1
Dec 19, 2008about 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?
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?
4 500 Gb Disks In Raid 10 Or 2 150 Gb Raptor Disks In Raid 1
Apr 27, 2008I would like to hear which configuration you think will be better for a hosting server.
I have allready a raid controller in the server.
I am more concerned with security.
15K Rpm SAS Disks Greater Than 146 GB
Nov 2, 2009Currently we're using HP servers with 4 hot-swap bays that hold 3.5" Seagate Cheetah 15K RPM SAS disks, which we can get in 300, 450, and 600 GB flavors.
I'm looking at the HP DL380/385 models which use 2.5" SAS disks. About the only decent 15K RPM SAS disk I've found in 2.5" form is the Seagate Savvio, but it doesn't come any larger than 146 GB.
Anyone know of another enterprise-class SAS disk that has all of the following attributes: 2.5", 15K RPM, SAS, and at least 300 GB?
(Please, no 10K RPM or SATA recommendations like the WD Velociraptor. I won't consider anything that's not 15K RPM SAS.)
Restore Disks
Jul 25, 2009I do not have a restore disk for my Toshiba laptop and there is a virus on it. Can I use my restore disk from my HP computer? Both use windows XP?

Aug 31, 2009Hardisk brands all had their ups and downs over time. So almost all brands made sometime bad drive models that failed (yes, even IBM)
I just finished reading an article that currently for servers it seems Seagate is the best (currently).
Some say Western, some say Maxtor, I heard everything. It seems nobody agrees or there isnt one that actually has the lowest failure rates.
It would be nice to hear from real experience on servers scenarios (not office, or desktop). The article also said Hitachi was one of the worst and my eyes just popped out. I found reviews of people here that said Hitachi where the bests. So to conclude it seems everybody has their own preference.
It would be nice to hear some Datacenters or people with tons of servers. I suppose recovery centers and datacenters probably have the best stats on which disks are failing the most.
Mega Database Disks
Jul 27, 2007How do you handle your mega space requirements for your high-use databases? Do any of you work with storage in the terabytes? If so, what kind of hardware and setup do you use?
Do you just have many commodity servers with maybe 100GB or so in each, or do you have some kind of shared RAID array set up? Or some kind of SAN?
Keep in mind I'm not talking about network storage (i.e. slow, personal use, file server) but rather high-speed intensive high-read/high-write database requirements.
What are the options for implementing such a solution?
What types of products fit such requirements? Could you comment on what things to look for when purchasing such a set of products?
Replace Disks With Little Downtime
Feb 12, 2008I colo a 1U machine with 2-36gig drives. They're not in RAID, and I have it set to rsync backups to a remote machine on a regular schedule. I have another remote machine functioning as a secondary DNS. Neither of these 2 are on a large upstream pipe. I just bought 2-147gig drives that I'd like to replace the 36g's with. How does this sound for a scenario to accomplish this with little downtime (pre-pardon my noob'ish ways):
1. Do a complete rsync of the filesystem to my remote machine as well as sync the mysql db's (to 1 remote drive).
2. Pop that single rsync'd drive into an external enclosure.
3. Travel to datacenter, once there, plug external drive into laptop and start up a VM that boots off of that drive.
4. Sync again so external drive has the most up-to-date data.
5. Change over IP's from colo to VM on laptop.
6. Shutdown and swap out drives in colo'd box with the new ones.
7. Setup new drives as RAID 1, install OS, then rsync filesystem over from laptop to new drives in colo'd box.
8. Change back IP's.
What am I missing, or is there an easier way without a 2nd colo/dedicated server? Currently, the colo'd machine is using about 1.3Mbit/sec outbound and it's running a low load.
Linux Hot Swapping Disks
May 30, 2008I have a server with SATA- Hot Swap disks. I can do this, and swap out a disk, and re-partition
the new one, however the running Linux kernel hangs on to the old partition table in memory.
So even though the disk is not in use, and has been re-partitioned, I still need to reboot to
get the kernel to see the new partitions, and use them. Is there any way around this?
How to force kernel to re-read disk partitions on non-system disks?
Mail-in Hard Disks
Mar 19, 2008anyone know any managed dedicated server provider who we can mail our hard disks to? We have a small pipe to the Internet and this is the only avenue we've thought of.
Or perhaps another solution that we haven't thought of?
Hot Swap Disks And CentOS
Dec 2, 2007Up to now we've been using CentOS with SCSI/SATA disk shich weren't "hot swap", and now we're upgrading to a Dell PowerEdge 1950 revision III with SAS hot swap disks on a PERC RAID 6i (new model of raid controller from Dell).
OF COURSE, Dell ONLY supports Windows (and Red Hat at the very most on the Linux world) so we were told by a Microsoft Tech that to be able to extract a disk and replace with another it had to be done via software. (The software powers the disk down and then you replace it)
Does anyone use CentOS with hot swap SAS disks? Do you use any special software to monitor the disks and/or replace them?
Hot Swap Disks + CentOS
Aug 7, 2007We're about to buy a Dell Poweredge 1950 with hot swap disks in a raid 1 configuration (might even think about other raid combinations).
We will be installing Centos 5 (never tried it - normally use Centos 4) + control panel
The question is: what happens when a disk fails? How do we find out?(Apart from looking at the server) Any software notices?
Once noticed, what is the standard procedure to replace the disk? (Remember they are "hot swap") Do you just pull one out and replace it? Surely you have to rebuild the array...
Serving Data From 2 Hard Disks
Mar 1, 2009I have a server with 2 hard drives, say drive A and drive B. Right now all my files, database and data is on drive A, and drive B is empty. Since I have another drive available, I want to split the load between the two drives. I'm ok with having the web pages and the database on one drive. I mostly want to just have the data (I have about 500GB of data) split between the two drives. Note that I want to avoid duplicating the data. I want to have each file on either drive A XOR drive B.
Should I map a separate subdomain to drive B and then use that subdomain to serve the half of the data thats there? Is there something I can do with hard/soft links on the server so that even though the data is on 2 drives, users still use the same url to access data on either drive? Any other options?
Do Hosts Stagger RAID Disks
Sep 14, 2008if I order a RAID from a host, can I be confident that they're not going to put two of the same make, model and order in there?
Or at least run one of the disks for a significant time before using inserting into the RAID?
Firmware Update For WDxxxxYS Disks.
Jan 11, 2007Since purchasing 16-disk arrray NAS server 4-5 months ago, 5 disks have crashed so far. They are all WD4000YS. They're all "Raid Edition" which supposed to last longer than typical drives. It has been puzzling me until now.
It turns out that "Data Lifeguard" feature was confusing the RAID controller to believe that the disk was dead, hence the "failed" disk. AFAIK, Western Digital released firmware update on 01/09/07 that's supposed to fix this.
[url]p_faqid=1493&p_created=1168299631&p_sid=vfEX7qri&p_accessibility=0&p_redirect=&p_lva=&p_sp=cF9zcmNoPTEmcF9zb3J0X2J5PSZwX2dyaWRzb3J0PSZwX3J vd19jbnQ9MiZwX3Byb2RzPTAmcF9jYXRzPTAmcF9wdj0mcF9jdj0mcF9zZWFyY2hfdHlwZT1hbnN3ZXJzLnNlYXJjaF9mbmwmcF9wYWdlPTEmcF9zZWFyY2hfdGV4dD1XRDQwMDBZUw**&p_li=&p_ topview=1
So, if you have WDxxxxYS on your pre-production server, pull them out for a firmware update first!
For me, I can only swap "hot-spare" out for a firmware update. For other disks, I'll just have to wait for them to "drop" out of the array first. I cannot take this server offline at all. Any suggestions?
