Data Center

what is the difference between a server room and a data center?
i need to find an image of a data center for an ad. i thought this was the same as a server room. Apparently there are subtle differences. can anyone tell me what they are?

A data center is a facility used to house computer systems and associated components, such as telecommunications and storage systems. It is also a more globalized definition used when describing a company's overall functions. (ie, tv station). A server room is the centralized location for all IT related equipment that is part of a data center facility. (use links below for visual reference)

How different BRI lines are terminated at other end i.e at Data Center or Network Opeartion Center?
How different (so many) BRI & Lease lines are terminated at other end i.e at Data Center or Network Opeartion Center and what equipemnts/ cards / circuits are used on routers in DC/ NOC to terminate them.

Most are terminated as pri (23B +d)

What is the formula to figure out how much HVAC you need in a data center?
Building a Data Center for the first time.

Don't you figure out how much heat energy is being generated by the computers/lights and what not, what the rate of diffusion through the walls is, and what your goal temperature is? Sounds like the energy equation to me with heat generation. You might even be able to use thermal resistance methods.

Why do data centers measure power in Amps? A data Center Provider will measure the power consumption in Amps?
A data center provider will charge for power consumption based on Amps and not Watts (which is measurement for Power). Why? Dc vs AC power?

The utility may charge for kwh but, given the fact that electronic equipment generate large amounts of harmonics, which translate into a very low power factor and overloaded feeder lines, there may be a surcharge for it. .

what are the various processs taken care by a data center manager? what are the various problems faced?
i need to understand the various equipment used at a data center. what are the various regular processes and what is the irregular work? which are the good brands for equipment and which software are better?

thats an incredibly vague question. (no offense, just the nature of a data center makes this vague) i work in a data center... Equipment run are servers, large A/C units, backup batteries, backup generator, and includes electromagnetic shielding or thick concrete walls, etc. regular processes are routine drive light and error light checks, temperature monitoring, upgrading servers, or adding servers to a farm, replacing bad components, automatic scheduled test cycles on teh backups batteries and generator, load testing for the generator, load evaluation on servers and the server network, etc. irregular work might would include replacing communication racks, server racks, replacing cabling, having to physically attach a monitor to older servers for diagnosis, maintainence on automated data backup systems, restoring from backup (due to major failure of a server or SAN, usually fault tolerance or automated recovery can take care of this). good equipment is entirely dependent on what your doing. Cisco and Nortel are excellent networking manufacturers, i prefer Cisco, but best to stick with one brand. servers will vary depending on what your doing, Dell, HP, IBM, etc. we prefer ESX for SAN management and VMware for virtualization. Be sure you have good cooling, i know Dell offers a program that calculates how many BTU's of heat Dell server produce, and you need at least that much cooling to counteract that heat. Good quality cabling (systemax, etc.) is advised because you wont want to keep upgrading your network cables due to age (shoot for upgrade for prerformance here) when avoidable. very important - remote access controllers are great, they require an additional netowrk connection but you can remote into a system and manage it without having a monitor, you can see errors and adjsut the bios without having to attach a monitor or physically touch the server.

How many data center need for game internet service covering whole US Area?
Interest in game service in US, but I am not sure how many data center needs for covering whole US Area.

one data center should be fine, the number of servers depends on how many users you expect to have playing during peek hours. figure 1 server per 100-10000 players, depending on the game. about 40 servers per rack. (1u servers) (network equipment needed too) . a few hundred to a few thousand racks per datacenter.

What would a good title be for me if I write office building and data center proposals and quotes.?
I also write and manage policy and procedure documents, I sit in on the sales meeting and calls but I am not a Sales person, I am the liason for tenants and management, any ideas would be appreciated.

documentation and procedure manager but I don't know any office assistant run polices and procedures.

How to design corporate data center?
We are proposing a datacenter for our corporate needs; consisting of web server,internet line,intranet line for corporate users,if anyone can suggest basic configuration of interconnection of various devices for the data center?How routers,firewall,swithches,Antivirus server,web server,nodes managment servers are interconnected?

An datacenter needs much and more things then u ever think it requires everything like lots of power backup lots of cooling and fire-detection systems lots of storages lots of blade servers everthing comes with an immense quantity but above of all it depends upon the needs u have suppose ur running an Exchange server in an production environment and u gave every user the limit of 2gb of storage and urs user"s profiles are connected to urs file server then u can think that how big the requirement can be So conclusion is that everthing depends upon urs requirements but i belive most of the companies give this tedious task to various telecom companies Like in our country the leading providers r Tulip,sify etc for Easy administration u can switch to windows server 2003/2008 but u know its vulnerable linux is good choice for routers its always cicso and for server hardware its dell which i believe is cost efficient and robust but.. i heard that sun microsystems r cool to even u can try thier products for 60 days and they dont even will ask u the reason all u have to do is go to their site and submit form but u have to pay for shipping charges And above all u need to budget for the expenses :-) if u really wanna explore in the world of datacenter then go to this website http://searchdatacenter.techtarget.com its really cool Jai Hind & Goodbye

What is the difference between a level 1 and a level 3 data center?


I don't think there is a definitive answer. I think it depends on the host.

I am doing my term paper about IBM power 6 blade server and data center for core banking?
In my architecture I want to incorporate DB , APP , reporting clusters on blade , Is it possible ? I mean on one blade center I want to have 3 server clusters .

Hi, It would help if you wrote the details of your chosen OS and programming (or scripting) language. Bye, BR.
