Servers
- The Performance - Scalability
We
all know servers. Many of us believe that a server can do everything.
Some believe that particular tasks require special servers. Only few
believe that a server does not require any hard disks or fans.
However, it's all very easy. The result of server innovation is a
blade centre. This mode of running servers is not all that new, but
has established itself today for efficient use in the small to
mid-sized sector.
Following
years of IT expansion, many companies often possess a large number of
servers. All servers have different connections and a variety of
components and spare parts. In order to tidy up these structures, a
platform should be chosen that standardises components.
The
IBM Bladecenter allows the running of up to 14 servers (blades) in 7
height units. Apart from the blades, it also includes all components
for power supply and network infrastructure in the LAN and SAN
direction. The network units are modular and can be used by
manufacturers such as Cisco, Nortel, Qlogic and Brocade. All systems
have a redundant layout and provide a fail-safe system for all
functions from the first blade onwards. You will obtain an entire
"data centre" in a quarter of a cabinet! The necessity of
IT availability for companies is increasing. Who can do without
e-mail services for more than a day? The Bladecenter innovation is
robust and fail safe. With just 8 connections to the outside world,
you can get up to 112 CPUs (cores) on the road. And how about the
price? From four blades upwards, it comes at a better price than four
conventional servers.
Scalable
from 2 to 112 cores
Made-to-measure,
yet standardised, the IBM Bladecenter sets standards for
state-of-the-art IT. The features allow dynamic expansion for
all customer requirements:
Central
administration of all systems
Open
SAN and NAS connection with internal Cisco, Nortel, Qlogic and
Brocade switches
Infiniband
10 GBit/s for LAN
4
Gbit/s FiberChannel or 1 GBit/s iscsi SAN
Blades
with Intel, AMD and power processors
Blades
with up to 8 cores and 32 GByte RAM
2
x silicon- and 1x flash-disk support
Redundant
power supplies with efficiency < 90%
Redundant
central fans 230 V supply
Connecting
14 servers with 2 cables
The
iSCSI and FiberChannel (FC) interfaces can be used to connect into
the different worlds within SAN, allowing all servers to boot or
mount their (virtual) disks from the storage system.
Redundant
and twice secured
All
units have a second physical backup. In case of a hardware failure,
your IT will not come to a standstill. IT availability
is one of today's production factors.
