I know there are a lot of experienced hardware guys on here, so I wanted some input on 1.5TB drives. Are they reliable enough to be used in non-mission critical storage servers? 99% of what we do is OEM (Dell) equipment, so I don't test raw hardware much these days.
I've read a lot of negative things about Seagate lately. Can anyone chime in with specific models they've had positive or negative experiences with from any vendor? Reading some reviews on the WD 1.5TB Caviar Black drives, there seems to be some weird issues with them going into a recovery cycle.
I have a couple of Dell 1950s and in one of them, I have 2x Seagate 15K.5s that I purchased through Dell and I also have a spare sitting in my rack in case one goes bad, also from Dell.
I was going to be repurposing one of my other 1950s and was going to get two more 15K.5s for it, but wasn't planning on getting them through Dell (rip off?). This way, could still keep the same spare drive around in case a drive went bad in that system as well.
When I was talking to my Dell rep recently when purchasing another system, their hardware tech said you can't use non-Dell drives with Dell drives in the same RAID array because of the different firmware between them.
Anyone know if it is true? Anyone have any experience with using drives from Dell in conjunction with the same model drives from a third party retailer?
What is the best way to find out which filesystems and harddrive drivers you can remove? Obviously, i need ext2,3 but how do you find which HD you only need?
I was just wondering whats the real live experience or difference on using Western Digital Caviar series (green, blue or black) on a DC environment vs the RE which are suppose to be for enterprise business.
On the WDC website the caviar series are targeted under desktop disks not servers. But allot of servers and providers use them. If you have servers your suppose to use the RE series, I exclude raptors as I only want to compare medium performance disks here.
I'm building a couple of VPS host servers for a client.
Each server have to host 20 VPS and each server will be 4 cores with 32GB of ram. So CPU and ram should be just fine, my interrogatioon now is hard drives. The company owns the machines, but not the drives yet.
I searched a lot on your forums but found nothing relating on VPS. I'm basicly a DBA IRL, so I have experience in hardrives when it comes to databases, but it's completely different for VPS.
According to my boss, each VPS will run a LAMP solution (having a separeted DB cluster is out of question for some reason).
First, raid1 is indeed a must. There is room for 2x 3.5 drives. I might be able to change the backplane for 4x2.5, but i'm not sure...
I've came to several solutions: 2x SATA 7.2k => comes to about 140$ 2x SATA 10k (velociraptor) => comes to about 500$ 2x SAS 10k with PCIe controller => comes to about 850$ 2x SAS 15k with PCIe controller=> comes to about 1000$
They need at least 300GB storage.
But my problem is that the servers do not have SAS onboard so I need a controller and in my case the cheapest solution is best.
But I'm not sure that SATA 7.2k will hold the charge of 20 complete VPS.
Does it worth it to go with SAS anyway or SATA should be just fine? With SATA better use plain old sata 7.2k or 10k drives?
That's a lot of text for not much: What is best for VPS: SATA 7.2k, SATA 10k or SAS 10k?
Do the old RLX Blade servers use 'mini' hard drives? I can't find an answer anywhere. I seem to recall that they use smaller 2.5" drives. Is this the case?
And, if so, do they make "good" drives worthy of being in a server in that size? Are they essentially just a laptop drive?
My server has been formated it has two drives. I have my back up on the second drives. What is the command I use to list the drives and how to mount the second drive.
Does anyone have experience with SSD drives in a server environment? I've seen now a few offers with SSD (Intel) and wondering if the speed is noticeable?
Are they worth it? from what I have been reading is that they a superior in reliability, but have issues with limited write cycles.
Anybody know the best place to get a really cheap server with at least 250GB drives? I'm assuming most providers offer HDD's of that size on relatively cheap systems now if we're just looking at SATA.
The machine doesn't need to be anything special, I don't need a ton of bandwidth.
Basically this will be an extra backup machine to pull backups from servers instead of my usual "pushing" of backup data.
So to clarify, I'm looking for a simple machine pretty much anywhere with some drive space! VPS just won't cut it because the drivespace they provide is too expensive (yes, I understand they have nice drive setups though).
RAID etc is not needed, I'm not running anything mission critical but would like to have more locations in place to hold backups for me. WHT worries me alot
I can't find providers with 10Krpm HDs+ offshore and they have to have good support. Also I need atleast 2Tb over 100Mbit.
The reason why I need it to be offshore is because my client wants to have a subtitles sites and I'm not exactly sure if its legal or not in america and UK. Also netherlands or germany is preffered I looked at swiftnoc but not sure if they have 10krpm hard drives.
I'm sure by now we have all noticed the Liquid Web ads for solid state drives by now. These offerings would make for incredible database servers, among other things.My questions is:
How many of you are going to run out and get a solution like this, from liquidweb or anyone else? Why or why not?
I am thinking of purchasing Samsung Spinpoint F1 drives, either the 750 GB or 1000 GB one. The purpose would be to put them on a large RAID array (e.g. 14 drives in RAID 10/RAID 50). The price and performance looks good. However, I have read many mixed reviews about the drives. Does anybody has any experience with the drive? Again, this will not be used on a desktop environment, but a server environment. OS would be Win2K3 or CentOS.
I am in a little bit of trouble I got a couple (5) of 750GB hdds that I need backed up to another couple (5?) of 750GB hdds so I can save the data storage on them. They are in a Linux box with a LVM setup I also have a RAID ware card on it but not using any RAID # on them. I decided after finding out what I could do with it to go to Windows 2003 on the server and installing RAID5/6 on it.
It seems that I will have to give up all my data and have everything wiped off from the hard drives this is very sad for me but I still have a chance to save the data on them. So I am thinking of copying them to another bunch of hard drives and then re-add it once the system is in place.
I was looking at this [url]
But thats clearly too expensive as I just need to back up 5 hard drives (750GB/each) and just need to do it one time. Anyone have any suggestions to this or how should I go about doing it. It doesnt have to be right away but its good to know my options.
Is there any place where they might to do this kind of stuff they let you rent their machine for a couple of hours for a fee so you can back up your data? The server is a COLO and the hardware is mine so I have every right to take it off and back it up with no problem from the datacenter.
am getting new server with 2 (73GB) hard drives i need to know the following:
1.I need to put /home in one hard drive 73GB and the other partitions like /boot, /tmp,/usr and /var on the other drive
where should i put /home? on the primary or or secondary drive?is there any effect on the speed?
2. Am used to servers with 1 drive. is there any difference when it comes to security aplications such as APF,BFD,mod security and other aplicatuions settings?
3. in general should i take the same actions when handling a server with 1 drive and server with 2 drives?
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
I have a dell POWER VAULT 725N utilizing a 4 HDD RAID 5 setup.
Server has died and bios error message shows that 2 hard drives had failed. I can not boot to windows.
Data is very crucial, what are my options for data recovery?
I really hope I can recover the data, I doubt that two HDD actually failed at the same time without giving any warnings. I hope its the raid controller.
Would like to hear pointers from the community on how to recover important data from the RAID.
Are there any companies/software that would help in this assuming it is a hdd failure and not a controller issue?
I'm currently running Dell 1750s, 1850s, and 1950s in a colo facility. I am not happy with the 1850s and 1950s power consumption. My 1950s have a single quad core 5310, 2GB memory, dual 15k 73GB drives, dual power suppies and are running at about 1.9 amps with spikes up to 2.4 amps. My applications are disk bound and the servers typically run at a load of .1 to .2.
I'm looking for alternatives to the 1950 that use significantly less power. I need at least 2 Hot Plug SAS drives and would like to have it in 1U. I run 2GB of memory. Dual power supplies would be nice, but are not absolutely necessary. I'd rather not go with a non-hot plug solution, but may have to consider it. I will probably buy 10-15 servers soon and would like them to be identical. I'd prefer buying a name-brand.
I installed 2 SATA raptors drives on my server. I formatted/partitioned one of the drives through WHM. After rebooting both drives disappeared. They are still detected within the BIOS but not in CentOS. It is possible that I installed a wrong driver or made a bad configuration change.
Server Info:
CentOS 4.6 64bit cPanel/WHM Motherboard: [url]OS is running on a 250GB IDE drive 2 SATA WD Raptors (That I am trying to get to work)
I ordered a new server... ah, looking forward to blistering fast speeds... with 7200 RPM SATA drives. The quote said they were 2.5" drives.
I get the server, look under the hood... They're LAPTOP drives!
WD 1200BEVS (WD Scorpio), listed as 5400 RPM!
Is this normal?? I mean, this thing has to burn at 85% CPU 24 hours a day. Should we return it and what manufacturer should we suggest for the drives? I can't seems to even find 2.5" SATA drives for non-laptop use.
