i know the subject may been talked a lot of time,
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.
Within 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
running new servers on 500GB+ hard drives, how are these drives performing when they become 50% full?
Can they properly be 50% or more utilized on a cPanel like server with 200+ acccounts?
trying to get my Win2k3 Standard R2 server to work.
Problem:
I did some Windows update around 3am this morning but during the update process. I lost Remote desktop connection as my machine is do several attempts to connect with the remote server. I cancel the attempt after several try. I figure i can remote desktop back in again if i wait for a bit but I couldn't re-establish the connection with my remote server. So, I drove to the Datacenter to check it out and it turn out the machine have rebooted and I'm stuck with "NTDetect failed" error message. After some googling, I was trying to fix this error by copying NTLDR and NTDetect.COM into C: but when i tried to use the Win2k3 CD to go into Windows Setup and repair. I got an error message telling me that "Setup did not find any hard disk drives installed in your computer...".
After some googling, I found the two Maxtor SATA hard disks might be the problem and one soultion that i found was to disable the SATA or set it to IDE since the motherboard have nvida RAID controller onboard. I check the BIOS and the RAID is set to disabled and then i tried to disable SATA and only enable IDE. It still give me the same error message about not able to find any hard disk.
I'm on my last rope here. I'm short of reformatting the hard disk and do a fresh reinstall but I will like to avoid this.
Does anyone know if cancel Remote desktop connection attempt during Windows update process cause this NTdetect failed problem or something else that might related to my hardware. I can assure you that two SATA hard disks shown on BIOS.
The soultion to NTDecte failed problem seem to be just copying NTLDR and NTdectect.com into C: but since i can't even get to Repair mode during Windows setup with no disk install error. Can someone recommand how to solve this problem?
The motherboard that i use is ASUS M2N-MX SE AM2 NVIDIA GeForce6100 / nForce430 and the BIOS is American Megatrends Inc.
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?
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?
Which is the best platform when going with the tun/tap tunneling. Is it better to use Xen or Virutozzo for using the Tun/ tap feature.
My customer is trying to setup something like this on his vps.
I was wondering what would be the best solution either xen, virutuozzo or hypervm.
He is trying to setup something like this on his vps:
" i am asking for a vps with two nics enabled...a set of 8 ips assigned to the second nic to send, receive and pass traffic as a vpn server."

I am having quite a challenge getting openvz to work on centos 5 with a adaptec RAID card.
The driver likes the plain jane kernel..but then...
Configuration [OpenVZ (2.6.18-8.1.14.el5.028stab045.1)]
***NOTICE: /boot/vmlinuz-2.6.18-8.1.14.el5.028stab045.1 is not a kernel. Skipping.
There is also another issue not being able to disable Selinux.
I have tried the normal routes and even attempted disabling it in rc.sysinit..still...this "security framework" is able to load it..and cause problems.
Openvz and SeLinux don't get along..even a little bit.
So..those are the two probably seperate issues...that prevent the poor server from booting.
know of a Virtual Audio Driver that i can put on my dedicated Server that does not have a sound card.
View 1 Replies View RelatedI'm having problem with my IPB forum which runs on MySQL database (hosted on linux Fedora).
Our website was unavalable for a short time, and when it came back on-line, we found we cannot create new topics/add replies, in short, we cannot add new records to ibf_posts table. However, editing existing posts works, sending private messages works, so database seems mostly OK, apart from posting. Whenever we try to post/add new topic, we get IPS Driver Error. We have tried restarting MySQL several times, but it didn't solve the problem.
Looking at the error log, we notice the following lines (but we're unsure is it about this problem):

and then several hundreds lines like this:

It seems really strange that forum and database seem absolutely OK, that editing and private messages work (and Admin CP seems fine) but that it throws IPS Driver error on new posts only?
When paying for my server, I prefer to pay with PayPal. Is it normal when I want to pay with PayPal (if they except this), the hosting company also wants my CC number and CVV2 code. What's the use then of paying with PayPal.
I don't mind to identify myself with copies of driver licences, but CC is different story.
I have got a server with the following specs:
Dual Xeon 2.4 Ghz
6 Gb DDR ECC REG
1 HD 147 Gb 15K
On the board, there is an SCSI adapter which is an Adaptec 7899.
This configuration is working perfectly under Windows 2003. However, as per customer request, I have to install CentOS, RedHat or Fedora. Even Debian is OK.
However, during the install, the OS find NO hard drives and the installation is aborted.
I googled some time and it looks that there is 1 million people looking for a solution on how to install Linux on a machine with an AIC-7899.
The installer loads a driver AIC-7XXX but didn't find the device anyway.

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 my disk performance to slow? Does the performance suggest it's a IDE disk?

View 6 Replies View Relatedabout 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

On a normal shared hosting server, what kind of performance gains can you see using a SAS drive instead of a SATA II in raid-1?
View 6 Replies View RelatedI wonder which drive give the best performance? Look like they all have the same 15000 rpm. :d
Any experience?
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 .

For a server would a Raptor (10K rpm) Do better than same capacity SATA-2drive?
View 14 Replies View RelatedI'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.
I'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?
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;

how I can format all and reinstall
better the sata disk?
