HP Blade System c7000 Enclosure

HP Blade System c7000 Enclosure

 

What is Enclosure:

 

A blade enclosure is a box which contains 16 half height and 8 full height blade servers (C7000) also provide services like Power, Network, cooling, Onboard administrator, interconnects, insight display, midplane and management from single console.

 

If we are talking about standalone servers then they will use 2 U or 3 U in rack. But blade chassis is saving the U’s of rack as well and power.

C7000 need only 10 U (b) Up to eight redundant interconnects

It includes a shared 7.1 terabit per second high speed nonstop midplane for wire one connectivity of these blade servers to network and shared storage.

Here power is provided through shared pool backplane it ensures that full capacity is available for all the blade servers.

What are and How to manage Enclosure components
We can manage with (1) OA (Onboard administrator) (2). Insight Display
OA: it enables complete remote management for your Enclosure (C- Class). With the help of OA you can monitor power and cooling management. You can do capping on power as well from here.

Onboard Administrator is a physical Hardware and we have to insert into Server by default chassis is coming with one OA.  By the help of OA we can manage our Blade Chassis and blade Servers which are inserted in All bay. This is not used for Network or Data traffic it’s purely used for Management traffic.

Recommendation: For redundancy purpose you have to use two OA.

 
It also connects with server ILO to the management network. It provides SSO (single sign-on) to ILO.
It also has direct connectivity to the ILO externally but need credentials for that.
Insight Display: Enclosure is having one Insight display which is a LCD panel for setup and configuration. But Onboard administrator enables you more control of your blade system infra.

 Insight Display- with the help of this display you can configure Chassis at the very first time. You can use DB9 Cable to take console of this insight display. You can connect your laptop and configure chassis server.

 

Signal midplane:

This is PCB (Printed Circuit Board) a Passive signal which is having 24 layer and 1600 copper traces or more. It is having 180 PIN

Passive means that there are not active electrical components on this PCB board. On the front side it contain 16 power supply connector for servers and storage, choice is yours what you want to insert.

Behind passive signal midplane funda is like you are inserting one Server in bay and carelessly it damage that connector but no worry you can connect servers in rest of the bays with not damage connector.

Note: If this is Active PCI then it will short circuit and not work.

Note: Older generation enclosure might not support newer interconnects and vice versa.

 

Signal midplane provides connectivity within Server, Network Module, Fan and OA.
 Do you know how much PIN is having a Half Height and Full Height Server?

Half Height – 100 PIN

Full Height – 200 PIN but used only 180 PIN rest 20 is used for inter bay connection.

Do you know how many ports are having one blade server?

Half Height:

2 LOM (LAN ON Motherboard) ports they are inbuilt ports

2 Slot from Mezzanine 1 (SLOT only not a port)

4 Slot from Mezzanine 2 (SLOT only not a port)

 Full Height:

4 LOM (LAN ON Motherboard) ports they are inbuilt ports

2 Slot from Mezzanine 1 (SLOT only not a port)

4 Slot from Mezzanine 2 (SLOT only not a port)

4 Slot from Mezzanine 3 (SLOT only not a port)

180 PIN can connect with interconnect module (back side of chassis)

Bandwidth which we got after fully populated chassis will be 5.12 TB/second for All servers.

Calculation behind This:

Half Height: Signal connector of each device has a 100 PIN connector with 64 high speed signal pins. They are not wire like RJ 45, they are hard wired to the interconnect bays.

So 64 ÷ 8 (Half Height Server) = 8 Pins and it called = 2 lanes which is connected with each interconnect.

So one lane = 4 pins

1 Lane = 4 Copper tracer = 4 Pins

One Port is giving 10 Gbps speed

Take an example:

Half Height Server:     8 Ports x 2 Lanes = 16 Ports

                                  16 ports x 10 Gbps = 160 Gbps

And  160 Gbps x 16 (Half Height Server) = 2.56 Tbps x 2 (both way data upload and download) = 5.12 Tbps

Now G3 having 12 Gbps speed.

How to add new vlan in virtual connect flexfabric

This article will let you know How to add new vlan in virtual connect Flexfabric. I had a task to add new vlan in virtual connect Flexfabric (HP). Network team created new vlan and i want to use that for my virtual machines. so before adding you should calculate impact and how much critical servers are running on that chassis. After that you can start adding vlan to your virtual connect Flexfabric.

 

1. First log into server where virtual connect manager is installed

 

2. After that it will open virtual connect manager page here you have to provide ID and password

3. Here it will show you virtual connect manager options. here you have to go to Server Profile Management and click on Manage Server Profiles

 

4. Here you will see Server profiles tab and all the servers for this datacenter

 

5. Then you have to select a host on which you want to add newly created vlan, after selection click on Edit button so that you can add.

 

6. Here it will show you progress bar and it will take some time to open

 

7. After clicking Edit it will show you all the NIC settings below

 

8. Here you have to be very careful select the NIC for which you want to add vlan and click on edit symbol

 

9. After that it will show you uplink here select your uplink and search the vlan ( type the vlan number ) and click on filter it will show you the vlan for which you are looking

Same need to provide for other uplink

 

10. After finish this you have to click ok which is near to bottom of this page.

Here you have just added vlan in flex fabric switch now you have to add into VCenter as well.

 11. Open VCenter and go to Home > Networking

 

12. After that you will see Data Center and Distributed Switch

 

13. Right click on Distributed Switch and go to New Port Group option

 

14. Now here you have to provide Vlan name which will be reflecting for Virtual machines. Port Groups as well and VLAN type: VLAN. ON Vlan ID you have to provide which ID that is created on Network switch by network team.

 

15. On Ready to complete page you will see summary and click on finish.

1. IP Address for ILO ( ILO Vlan IP),

2. ILO Port should be connected with Network switch and that network port should be in ILO Vlan or whatever ip you are using.

After visiting to your Datacenter or where server is located ,follow the steps below:

1. Power on the Server.

2. Press F8 and it will open up the ILO setting window.

 3. Here first you have to go Network > DNS/DHCP and then click enter to get into the network autoconfig.
