1U servers | |
 |
1U servers are the smallest offered servers,
that are designed to fit into a rackmount.
Ideal for today's network, web orientated programs and special server software,
these are ideal for maximising the amount of servers where saving space is a premium factor.
|
1U Servers application: |
Firewalls
Multiple LANs would be desireable/required for:
Incoming T1/T3 conection
Protection your local servers
|
Internet Servers
Web servers for small to mid size companies,
with medium storage for data and logs
Secure POP3/IMAP email servers(with ssl)
|
Backup Servers
Servers with large storage
Backups should be done on a different server than itself
|
Raid
RAID1 - disk mirroring, is the most secure of any of the RAID levels and is exceptionally fault-tolerant
RAID5 - protects data against a single disk failure out 3 or 5 disks in the array
|
Clusters
Clusters are useful for large domain
If one system goes down, the other remaining servers can continue job
|
|
2U and above servers | |
 |
2U and above servers are used for maximum performance,
availability and manageability for business-critical workloads.
They are the largest servers designed for multiprocessor environments and
sophisticated storage and backup solutions,
which provide the power required to run modern network software such as SQL servers, web servers and much more.
A 2u server is double the height of a 1u server and a 4u server is 4x the height of a 1u server.

Blade servers | |
 |
Blade servers represent a rather new direction in server systems.
The main feature of the given technology - is the opportunity to achieve high density of accommodation of computing resources:
in the standard chassis in height 4U it is possible to place up to 10 "edges",
that is up to 20 processors Intel Xeon.
Another important advantage - is convenience of management:
the server chassis already contains the switch of the consoles,
option of remote management of servers over a network.
