Why we are using Blade servers?

Blade servers are smallest servers available in the market.

We have different model servers in the market like ML & DL servers, but for these servers we have to maitain individual power supply, individual fans etc…so after that HP reduced the server size and come up with a plan of maintaining blades in enclosure to make server size small. The main difference between DL & Blade servers is DL servers we need to maintain individually but blade servers we can maintain all facilities in enclosure itself like power supply and fans everything to reduce cost and to easy maitainence of infrastructure environment.

The HP Blade System Matrix simplifies the use of IT applications and business services within an organization by offering IT capacities as a pool of resources which can be tapped into at any time in line with requirements. Servers, storage, networks, management tools, power supplies and cooling systems are offered to the user basically as an individual, integrated product, from which only the services actually required in a given situation are allocated and used. In a virtual IT infrastructure of this type, resources can be quickly reconfigured and made available according to the precise needs of the individual business units.

The HP Blade System Matrix solution consists of the following individual components: .

• Blade System c7000 Enclosure• Blade System servers (ProLiant or Integrity-based)• Insight Dynamics and Insight Control management software• Virtual Connect Flex-10 Ethernet and Fibre Channel Module• Optional Storage Works Enterprise Virtual Array (EVA)• Support for Windows, Linux, HP-UX, VMware vSphere, Microsoft Hyper-V and HP Integrity Virtual Machines.

It all starts with the hardware. HP's Matrix product is built from existing HP hardware offerings,

including the EVA4400 and Blade System c7000 blade chassis. In the mix are the usual Fibre

Channel SAN fabric switches and Ethernet switches. However, the two network switches really

don't play into the overall picture. This is possible due to the 10G Ethernet modules and the 8Gb

Fibre Channel links present in the chassis. Essentially, each chassis has all the bandwidth it

needs with these links, releasing administrators and the Insight Orchestration software from the

onus of having to interact at the layer-2 level to provide VLAN assignments and such.

We have two types of enclosures:

1) C3000 -6units size.2) C7000-10units size.

C3000 :

Half-height device numbering :

Full-height device numbering:

The C3000 enclosure can accomidate:

8 Half-height servers (or) 4 Full-height servers.

C3000 FAN bay numbering and configuration The FANs on the back of the C3000 enclosure must be configured according to the number of devices installed in the enclosure. Here is how they are numbered:

The C3000 enclosure is delivered with 4 FANs installed in BAYs 2,4,5 and 6. This is enough cooling power for a maximum of 4 half-height servers, or 2 full-height servers. If you install more servers than you need to ADD 2 more FANs in BAY 1 and 3.

C3000 POWER SUPPLIES numbering and configuration The C3000 enclosure can have up to 6 power supplies. Here is how they are numbered:

Depending on the number of devices installed in the enclosure you may have a different number of power supplies installed. Note that the power supply is oriented differently in slots 1,2,3 and slot 4,5,6.You can have different level of redundancy for the power supplies.

C3000 Interconnect modules

The interconnect modules must be installed on the back of the enclosures and are mapped to the NIC and mezzanine cards of the server blades. Here is how the ports are mapped on a C3000 enclosure:

C7000 : Numbering of the cells In the C7000 enclosure you can install either full height cells or half-height. The numbering is a little different in the second case because you have more slots available.

Numbering with full height cells

Numbering with half-height cell

C7000 Fan Numbering and Configuration The C7000 enclosure offers a maximum of 10 FANs for optimum cooling. The numbering is as follow :

Depending on the number of Servers installed you may have to order new FANs for your enclosure.

C7000 Interconnect modules The interconnect modules must be installed on the back of the enclosures and are mapped to the NIC and mezzanine cards of the server blades. Here is how the ports are mapped on a C7000 enclosure :

ACCESSING THE BLADES

Local Access

On the BL860c and BL870c there is an option to attach a cable on the front panel of the server blade. This cable (SUV) allows several connections :

Remote Access

You have several ways to remotely access the Blades or enclosures .

WEB access to ILO: Telnet to the MP Telnet to the servers installed in the enclosure WEB access to the Onboard Administrator (enclosure) Telnet to the Onboard Administrator (enclosure) Serial connection to the Onboard Administrator

WEB access to the Onboard Administrator All you have to do is to enter the IP address of the Onboard Administrator in a WEB browser, but make sure you have the https prefix . Of course you need to be on the same network. You will then display the login page for your enclosure (something similar to this) :

Note : the IP address of the Onboard Administrator is configured using the insight display in the front of the enclosure. The initial username and password are usually attached to the enclosure when received.

Telnet access to the Onboard Administrator:

This is even easier, simply open a telnet session to the IP address of the Onboard Administrator (same IP as the one used above for WEB access). The login will ask for a username and password, and these are the same as the ones used for the WEB access. Here is the command available:
