I have a Switched Rack PDU AP7921 in use and it was working now for several months without any problems. But sice yesterday I have a problem with the network connection. I was not able to connect to the PDU anymore, after pressing the reboot button it was working again. But after a few minutes, the problem appeared again.
Is this a common problem of this APC PDUs? Is there a fix, for example a firmware upgrade or is it broken?
With all the high power servers/blade servers, the 40A (@ 110V) power limit is way too small. I am wondering if there is any colo space targeted for high density application, e.g. with 10 KW/cab limit for 60A @ 208V power drops. Does anybody know of such high density colocation space? East coast is preferred.
I have a couple of these and we are looking to throw them into our rack but I have a question, is it possible to monitor the amp usage on a certain port or is it only possible to monitor the whole device?
I have been hosting boxcheats.com with HostGator for a few months, and two days ago I ordered a dedicated IP address to see if it would help with seo. Traffic and Adsense revenue significantly dropped immediately after the dedicated IP was assigned to my account.
Is this normal when switching to a dedicated IP address and what is the cause for the instant drop in traffic?
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
I have one domain (just one?) that has a serial of 0 (on my server 5.9.57.170 , latest plesk)
Because of that, dns updates don't happen, dns servers don't respond , and my domain issuer is threatening to revoke the domain as it is not working as it should.
You can see the test here [URL] .... when you enter the domain auringostaitaan.fi
In trying to fix this i have switched the dns off,changed the mode, enabled RIPE, but i get what it says [URL] ....
Note: See the sample of SOA serial number generated with the selected format. If the resulting number is less, than the current zone number, the modification may cause temporary malfunction of DNS for this domain. Zone updates may be invisible to Internet users for some time.
I go to Mail>Mail seetings, select all my OFF domains and click Acticate/Deactivate Services, select Enable from the drop down and click OK, but the mail service stays OFF.
I have recently started using the slave DNS manager in the Plesk extension library. I've found that even for DNS zones that are switched off in Plesk, failed sync/transfers still try to take place between the slave and master. Why is this so?
Shouldn't turning the DNS functionality off in Plesk remove the zone from the slave DNS server?
When a domains DNS functionality is turned off, it removed the zone info from the master, but no command is issued to remove it from the slave??
Domain that is trying to sync/transfer: example.com Plesk/Master server: 111.11.11.111 Slave DNS: 222.222.22.222
Code: May 6 08:51:39 ns2 named[1178]: zone example.com/IN: refresh: unexpected rcode (REFUSED) from master 111.11.11.111#53 (source 0.0.0.0#0) May 6 08:51:39 ns2 named[1178]: zone example.com/IN: Transfer started. May 6 08:51:40 ns2 named[1178]: transfer of 'example.com/IN' from 111.11.11.111#53: connected using 222.222.22.222#53166
a company gives me 40U rack with 16A by 600€ per month. It will be enough power to fill the rack with Dell servers R200/R300 with dual and quad core processors?
I woke up to a complaint by the ISP of spamming for one of our servers. More than 10 000 spams in a shared hosting environment. Found Steven online, thank God! PM him and he went to work looking for the culprit. He spend time monitoring and putting in scripts to catch the culprit and in no time found the faulty script causing the spams.
Really saved me a big headache on how to explain to the ISP. Thanks to the consistent excellent work done by Steven of Rack911.
Those unpatched forums of clients can really be a hassle and a big source of problems.
Our server count with The Planet only seems to be increasing as of late and I'm now starting to drive myself nuts with bandwidth counts, costs, etc.
My main concern at the moment is our total bandwidth. While we might have a server with a 2500GB limit only use 50% we might have a 1500GB limit use 200%. I understand that any overages are our own fault, etc but there must be a way for us to combine all bandwidth across all servers!
Is it possible for The Planet or any of the other big boys to provide private racks with pooled bandwidth without going colo?
I honestly dont understand why does DELL, HP and others price their 1U TFT monitors at 3 times the cost of the cheapest laptop?
I mean, dont get me wrong, I am all for spending good money to get quality products but I feel very awkward spending 3 times as much for a screen and keyboard when I can get their laptops WITH OS, MEMORY AND HDD for 3 times as less and use it as the 1U TFT monitors.
I can get a powerful server from Dell and HP at that price for crying out loud.
But then again, I might be seriously overlooking something here because what justifies such high price?
We have about 50 Cpanel servers in our own AS with two upstream providers. On the cpanel servers we use the following IPs in the /etc/resolv.conf:
1. IP of the cpanel server
2. DNS IP of the 1st upstreamprovider
3. DNS IP of the 2nd upstreamprovider
I realized, that the upstreampoviders nameserver are not answering that fast and therefore I was thinking to make my own DNS Server, which I could use additionaly after the IP of the cpanel server.
Is this a good idea or is it not necessary? If it is a good idea, which dns deamon would be recommended? If we build this server, maybe would be also nice if we could offer DNS as a single service. Is there any solution where we could create user accounts where user could manage there own dns zones?
I have 10 servers and it causes me $1713 monthly. I decide to get a rack and buy 10 servers from dell but the problem is: I don’t know anything about racks
What do you guys think about putting 40 Amps into one rack? Our colocation provider wants to whine about it and not allow it. When we're paying them $1000+ a month - I think this is just shoddy. They say it's for heat concerns - but really this just makes me mad. We have fifteen 1U servers in there, and can't get much more on our existing 20 amps.
Does anyone have any recommendations where I can get a few cheap (full length) rack shelves in the UK. They don't have to be adjustable but would prefer if they where full ones and not the half ones as I don't think they would take the weight correctly.
I was having problems with a host and Ed (one of the owners) helped me out creating a custom package to fit my needs and moving my sites across.
I've posted more than my fair share of tickets and they all get responded to quickly. All the tickets have either been my own problems for example installing scripts or sales questions.
I have had bad experiences with zero-U PDUs (i have only tried the APC ones). They keep getting in the way of equipment when you put them in the back of the cabinet .... I usually end up just having them standing up in the back of the cabinet and zip tie them to something so they dont fall down.
Am I just stupid and using these wrong or do other people have this issue? if you have an extra long server that sits out the back it bumps into the PDU so you got to nestle the PDUs into a corner of the cabinet.
What PDUs is everything using in various co-los? I might go with the 2U rack PDUs but with the need for 2 of them that is 4U wasted (and also since they are not very long you need some long cable runs for all of the equipment to plug into them)..
My nearest major city is Manchester, so naturally I'm looking for rackspace in the region.
Unless anyone has better suggestions, I'm thinking of going with NorthernColo. They start at £50/month but jump to £70/month if you draw more than 1A of current.
If my basic physics is anything to go by, 0.5A at our 240V means a maximum server power rating of 120 watts.
...are there any dual-core / 2GB RAM box configurations which consume less than 300W thesedays? My own USB mouse for my laptop consumes 50mA.
Otherwise I'm begining to think of their 0.5A pricing as being a bit of a scam, since the 1A price also pays for 2U worth of space.
