2. File Server:
In the client/server model, a file server is a computer responsible for the
central storage and management of data files so that other computers on
the same network can access the files. In its simplest form, a file server
may be an ordinary PC that handles requests for files and sends them
over the network.
File server acts as dedicated system like as network attached storage
(NAS) devices. This dedicated server is commonly implemented in
enterprise applications because they offer fastest data access as well as
offer higher storage capacity compare to non dedicated server.
Examples of File Server
File server is mostly used in various areas, for examples small scale
organizations, schools, and home network as well. We can configure of
file server with several methods; for example all computers can be
accessed over the “Local Area Network” while automatically setting of
file server. In the other way, like as business setting but here data
security is main concern, so file server allows to all client machines to
log in before getting to access the server. In other method, to need only
grant access for specific list of computer system, which are defined as IP
address or MAC address.
Advantages of File Server
There are few benefits of file server; such as
Less maintenance of your system
Data is highly secured, and easy to get data backup.
Easy to data recovery.

3. Easy to handle all files centrally.
It does not need change of application programs while changing of
physical file
Use of versions in future releases to allow programs from a previous
release to run against a changed database.
Easy to transition from old database to new database.
It helps to decrease the storage space pressure of client system.
It can be used one file server at once without changing of your entire
system.
File server can be accessed remotely with using of WebDAV and SCP.
Disadvantages of File Server
There are limitations of file server; like as –
It may be costly, if it is used in small companies, where two or three
employees work.
Require well qualifies IT person to set up and administer.
Increase network bandwidth while reading and writing files to and from
the file server by all clients.
If file server gets halt then all files are lost until it can be recovered from
back up.

4. What hardware specifications for file server needed for the following
requirements:
- 250+ users. 100 of them using design and rendering softwares(
autocad, 3dmax, lumion, photoshop) and the remaining
have normal work.(Ms office, pdf..)
- Current data 8TB but need minimum 20 TB and be able to expand
later.
- All files are on server and users access for read, write and rewrite.
- Switches are connected through fiber and configured for high
availability.
- Raid 5 preferable with many arrays.
Need to know please all details about hardware needed:
- Cpu
- Ram
- Disk (SATA - SAS- SSD)
- NICs
- Raid Controller and array
A file server is a computer containing files available to all users
connected to a local-area network (LAN). In some LANs, a
microcomputer is designated as the file server, while in others it is a
computer with a large disk drive and specialized software. Some file
servers also offer other resources such as gateways and protocol
conversion.
