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.
to ship 2 machines to LINX and DECIX from the US, and obviously need either adapters or just new cables. I'm just not certain what plug type is used at both or either location. I guess I'm looking for information similar to like what we have here in the US (NEMA 1-15 or NEMA 2-20).
We operate many Plesk VPS servers in a virtual environment for our customers and would really like the ability to allow Plesk VPS servers to switch to using our PPA DNS servers instead of having to have multiple ips on each VPS to run their own name servers. Not to mention the added nuisance of each customer having to register name servers and glue records.
We looked at adding the Plesk servers as nodes to our PPA cluster but the license jump and loss of Nginx is completely prohibitive. Is this possible?
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?
do dual power supplies use more power than a single supply?
E.g. Say I have a server than uses two amps, powered by a single power supply. Now if I switch to a dual supply (and say each supply has the same efficiency rating as the single), does my server use more power? How much more?
My simple view of this is that it probably does, but maybe not much. The second power supply consumes some power itself, but since its not under load, it doesn't consume much. Therefore, my server with redundant supplies might use 2.1A or 2.2A.
I'm building a storage server out of spare parts that are lying around here at the office. Purchasing a brandnew server kinda overshoots it's target, since all basic hardware is available lika a big Chieftec 4U casing with 2x 4drive SATA hotswap bays.
The machine will just be dumb storage for saving our backups.
The plan is to add a decent serverboard, proc and some ram as a baseline. On top of that a 3ware 8-port RAID-controller with 8 1TB harddrives (seagate has some nice ones).
Now the only issue i'm having is powerconsumption. The case has an 460W PSU, but I'm not sure if that's enough.
at getting PDUs for the new facility where we plan to move our servers to. Our cabinet will have 2*20a circuits, so we're thinking of getting 2 APC PDUs (1 per circuit). Some offer remote reboot capability.
Our servers (Dell PowerEdge) have dual power supplies, and I assume the best thing is to plug one power supply into each circuit, so things stay up even if a circuit fails.
So, how would this work if we want to reboot? The servers can run on only one power supply, so does that mean we have to click reboot on the web interface of each PDU at exactly the same time?
I've never worked with PDUs before.. just cheap power strips and a call to the datacenter
What are the best ways to reduce server power consumption?
I have a Dell Poweredge 860 (2.4ghz QC, 5GB RAM, 2 HDs) and it uses 0.46AMPs when running normally. The problem is at boot up it spikes for a few seconds here and there to about 0.6 and this is a real problem as I only have a 0.5AMP allowance.
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 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?
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.
