What is a difference between Network Operation Center and Data Center?
As I understood, DC is a physical location of computers while NOC is somewhat abstract term. It means servers, routers, wires, switches and all other equipment.
After speaking to a colleague about some major benefits of EC2 for on-demand hosting I've been very interested in learning more.
I've spent the past 2 evenings trolling through Amazon Doc's and blog posts and have a fair assessment about how things work but I'm at a stopping point.
There doesn't seem to be a dedicated EC2 area here on Sitepoint and the Amazon EC2 forums seem geared more towards 'advanced' users.
Are there any reliable communities that are more for the beginner?
I've got a LAMP webserver Instance running on EC2 but I'm very unclear about how to login and begin adding files and managing the data. I'm sure it's pretty simple but the documentation pretty much loses me when they start discussing Security Groups and public/private keys.
I'm not much of a server admin but have grown pretty comfortable on our FC4 dedicated boxes that we currently host on.
I am sending out an email blast to about 30000 addresses when I leave. Because this is the down-time for our site, is it possible to temporarily give Exim more resources to help process? Or would this even be beneficial?
If both questions answer yes, please let me know where I should look for instructions on doing this.
It takes up pretty much 90-95% of the cpu and memory at times if I do not kill the process. But even after I kill the process it comes back and immediately hogs up cpu load again causing it to go into loads of 8.00 or higher ( I have 8cpus ).
I'm guessing it's a no but if I start a VPS and it starts to eat ram or I think it needs more CPU can I just increase it? I'm talking about using OpenVZ.
We've just started to use a VPS, and so far no problems I've been looking at the resources and they seem a little high considering it's pretty much out of the box, and I've only setup 4 sites which aren't even public yet. The only thing I've changed is the php.ini to increase the memory limit to 32mb. My main concern is that these sites don't suffer when they go live.
In the Plesk control panel the memory says: 3.8 GB of 3.8 GB used; 47.1 MB available The 47.1mb is pretty much average, although I've seen it go as low as 115mb.
In Virtuozzo the system usage (resource: capacity) is usually around 60-75%
Both of these seem a little high, but I'm not sure if these readings are for the whole physical server, or just my portion of it.
Also in the (Virtuozzo) QoS alerts I've had quite a few Yellow zone, black zone and one red zone reports, at around 5am - quite possibly the quietest time on a server which isn't hosting any live sites yet. These have both been on the numproc and the privvmpages services (the red zone was one the privvmpages). Is there anything I should be looking at or is this fairly normal operation for a VPS? I have nightly backups scheduled for around 1am. These were originally set for 4am, but reports were showing that they were running out of memory, so I’ve now staggered the times of these to see if that helps. I've haven't changed anything resource-wise other than the php, so I thought it would be good to go from the start, but maybe it needs some fine tuning.
I am running CPanel/WHM as well as the WHMSonic plugin for a Shoutcast service. Now the thing is that my RAM limit is 4GB, but my RAM usage is always at around 3.5GB and above.
I guess it's mainly due to WHMSonic, so is there any way i could lower this RAM as on multiple occasions the server has locked up and shutdown,rebooted or had to be rebooted.
On top of that, the server load is around 10.00 or above.
Is there a resource controlling script which i could install?
I have seen some requests for cheap Virtual Private Servers. By saying "cheap" I mean under $20/month... However the those who posted the requests meant under $10/month...
I don't think that a virtual machine or container would cost $10 or less, but I've seen some providers to offer virtual servers with a very small amount of resources - a couple gigs of space, not to much bandwidth and 64 MB or 128 MB RAM - and to price them around 10 bucks per month.
Although I'd never go this way I'm curious to read what do you thin about such a marketing policy. Do you think that offering a VPS which can not even have a control panel because it doesn't have enough resources is a good practice? (I realize that there are different scenarios and some people probably don't need hosting automation software, but at the same time need a low cost virtual machine...)
I got a dedicated server running, which is administered by DirectAdmin, which I mainly use as a mysql server. Now my question would be, what would I do to give all resources possible to mySQL? I mean I don´t wanna take down directadmin and setup mySQL only, so I want to keep directadmin but give almost all server resources to mySQL?
What I did so far is adjust all tables, do indexes and stuff.
The background is that at certain times I face server loads of 40 caused by many external servers of mine querying the mySQL database on the server I am talking about.
So while the load is mainly below 0.1 it sometimes goes up to 40. So this peak I wanna slow down a little bit by giving all resources to mySQL. To say that beforehand splitting the queries from external servers is not an option - they all need to be done at the same time.
So I would really be interested and thankful in what you would advice to do to optimize the mySQL service?
I have a VPS where i have cpanel installed. I have noticed quite a number of times through my WHM Cpu/Memory usage that there are 3 instances of MRTG and they seem to be taking up a lot of resources.
I did not install mrtg and i don't even know how do i go ahead and view them
Can someone tell me how do i remove them and is it just me or are there actually 3 instances of MRTG running for everyone?
I am thinking about creating my own search engine and I was wondering what some basic server hardware would be required to do this (e.g., RAM, hard drives, memory, storage space). Would I have to run a minimum of 1TB on storage and 4 to 6GB of ram to do it right?
I and my colleagues often times run into misunderstandings about terminology. I'd love your input on the following - please also make suggestions of terms we should be including in our list - we will be posting these to our website.
CRITICAL POWER LOAD ("CRITICAL LOAD"): The usable electrical capacity at the data center floor and server cord. Does not include any ancilary load for cooling, lighting, common areas or other equipment. VERY IMPORTANT DEFINITION. Also called IT load, data load, server load, etc..
CRITICAL COOLING LOAD: The usable cooling capacity at the data center floor. Does not include any ancilary load for lighting, common areas or other equipment.
PARASITIC LOAD: The power and cooling load for all ancilary equipment and common area operation.
RETAIL COLOCATION: Multi-tenant, turnkey data centers that offer services down to the rack or partial rack / cabinet.
WHOLESALE COLOCATION: Multi-tenant, turnkey data centers that offer services down to the PDU. Typically require commits greater than 300 KW (2000 SF approx).
SHELL DATA CENTER: A building that has been pre-qualified for power and telecom access, with or without any other improvements (i.e. four concrete walls), and amenable to data center development and use. My become a single-tenant property or colocation.
COMMISSIONABLE (WHOLESALE / RETAIL) DATA CENTER / COLOCATION: An unoccupied, fully built data center previously in operational condition but that can be brought to fully operational status with minimal improvements and via the commissioning process.
EXCHANGE COLOCATION: Multi-tenant, turnkey data centers where ISPs interconnect and that offer services down to the rack or partial rack / cabinet.
CARRIER NEUTRAL COLOCATION: Multi-tenant, turnkey data centers that are unaffiliated with a network service provider.
NETWORK SERVICE PROVIDER (NSP) COLOCATION: Multi-tenant, turnkey data centers that are affiliated with a network service provider.
I am wondering which is the best data Center to get allow ping from both sites, europe and the USA. For now I am searching for an Data Center at the US East Cost but I am not sure which is the best, therefore I would like to here your opinion on this.
I am planing on building a small data center either in Waterloo, Ontario or in the surrounding area of Toronto, Ontario.
My questions:
1.) Is Waterloo a good area to build a data center? I know its a technology area but I havent seen much data centers from the area. And are there any bandwidth providers in the area?
2.) Anyone know a good place in the surrounding area of Toronto ontario where fiber lines will be easy to bring in? Mostly looking for something on the edge of the city, planing of purchasing my own land and a place where it will be easy to expand. Right now looking Bolton area or Brampton
3.) What bandwidth providers can be found in these areas? Need someone who can offer bandwidth for cheap like the do in the states so I can offer my customers cheap bandwidth also.
4.) If I open a data center in Waterloo ontario do you guys think there will be a good demand for colocation there?
During my minutes of boredom the other day, I spoke to a person from Open Pipe solutions LTD regarding a Data Center network. I wasn't interested I just wanted to know really. I was quoted the following:
20 Static IPs (Upgradeable) 15TB Premium Bandwidth Up to 100mbps Speeds Custom network name £32,000 setup fee ($64,000) £2,000 per month ($4,000)
Then you have buildings, servers, rack products & other necessities on top. Very expensive!
