Intergrating HP blade servers into a Cat 6000 back bone

Ok, im relatively new to this, so please bear with me.
We have a new hp blade server with 2 Cisco Gigabit Ethernet Switch Module's. Currently one switch serves 4 of the servers in the blade and one switch serves the other 4.
We would like both switches to load share and thus have redundancy if one was to fail.
Our current backbone is between 2 6000 Cats with 3 fibre connections, so a 3 gig ether channel between the two.
Everything is routed via this link and spanning tree stops any loops throughout the rest of the network, due to the 6000 route being by far the fastest and largest route. (3 gig and direct opposed to 1 gig and via at least 2 hops on all other connections/loops)
Now the concerns are, if we connect these blades, with there impressive backplane speeds (must admit I have yet to determine these backplane speeds but I no there quick)in the redundant load sharing way they are intended to work, will spanning tree opt to use the blade server as the back bone of the network...
Also another observations of mine is the blades use IOS and the cat's use KTOS... will there be any problems there?
Any thoughts, ideas or suggestions would be greatly appreciated. Please feel free to ask any questions and I will go away and find out the answers.
Many thanks.
Michael.

Hi Michael,
Well, This is fairly simple to implement. I dont know why those guys need 4 days to impelemt. Are they going to manufacture a new switch in 4 days :-)....
I guess you can go ahead wit this implementaion on your own and connect the switches directly to the 6500 as you want. The only suggestion is to go for etherchannel between the chassis. Follow the steps:
1. Check the root bridge on your n/w and also the priority set. If you ahev root bridge and secondry root bridge in your n/w with priorities 8192 and 16384, you are absolutely good to go.
2. If priorities are default, I would suggest to set the STP priority on your HP blade to be a little high than default 32768 to overcome the STP root bridge issue. use command
config t
spanning-tree vlan priority < value >

3. Set up the etherchannel between the chassis, if using multiple link to connect.
http://www.cisco.com/univercd/cc/td/doc/product/lan/cat6000/12_1e/swconfig/channel.htm
You should be all set to go.
HTH, Please rate if it does.

How should a segment my servers into VLAN's in a datacenter design

I am designing a data center with over 200 servers and I am trying to decide how to segment my data center into VLAN's. I have thought about putting all servers in a different vlan to guard agaist broadcast storms and also a failure that might effect the vlan as a whole. I know I can use storm control to limit broadcast storms.
Another thought is to put all Windows servers into one Vlan and all UNIX into another.
Another thought is to group the servers into VLAN's by the applilcations they support.
Can anyone tell me how they do this in a large data center and if any the pros and cons to doing it that way.

As stated you're going to need at minimum two 4000s. Since there are 200+ servers in this you may want to go with the 6000s. Obviously you'll need to do layer 3 and have a couple GigE trunks between those two switches to handle any cross switch traffic. Since you have so much riding in this data center you're going to want some horsepower at your gateway. Maybe look into redundant 3700's and use HSRP. Is this a design for a colo type data center or is it all internal servers to your company? I guess if it was the former I would split it out by *NIX / Win, and keep each VLAN down to a /29 and put 4-5 servers in each. This way, if you do have a problem it is segmented relatively well. There are so many variables, it's hard to say with just a few lines to go off of.

Good luck!!!

Clustered blade servers

We're currently investigating a hardware refresh of our production landscape and we've come across a bit of a stumbling block. For the record, we're not particularly big, currently running ERP 2005 with a database instance and the central instance on dual quad-core x64 1.83GHz processors with 16GB RAM each and two application servers on four quad-core x64 pre-Core-architecture processors with 8GB RAM each. It's all hooked together on a gigabit Ethernet switch (two gigabit connections per server using teaming) and all storage is internal to each server except for the database instance which has an external SCSI RAID array.
We're now upsizing and are finding ourselves once again on the very limits of what the x86/x64 systems available to us can offer, except this time, we're not sure it's enough. We're investigating blade servers as a potential way to move forward but the documentation of how a "clustered blade" server works is sketchy at best. Itanium, for us, doesn't really hold the answer; sure you can fit 128 processors into the same server but we don't have £1m to spend!
So, my questions are:
What actually is a clustered blade server?
How does it work? Do I assign physical blades to a logical server and they all work together as one much faster server, or is it just for failover purposes?
Is it still possible to use SAP's recommendations about keeping the operating system, SAP executables, the database, the database log file and the swap space (etc. etc.) on physically seperate drives if we move to Fibre Channel based storage, or is that no longer something to worry about, does it even matter any more?
Do SAP have any recommendations with regards clustered blade servers?
Has anyone ever had experience of using clustered blade servers to run ERP 2005? Anything I should know?
The impression I get of blade servers is that they are to servers what RAID is to hard disk drives, but I'd just like a bit of advice from anyone who can give it before I start spending money!
Many thanks,

You can export a VM with snapshots and import those to a later version.
If your snapshots were taken while the VM was running, then the running VM state file needs to be deleted. (the .bin / .vsv) as the running memory state is never supported when upgrading.
Now, the other issue. 2012 R2 cannot import a VM from 2008 R2. Only 2012 can import any of the 2008 releases, and the 2012 R2 release. (yes, there was a fundamental change made and 2012 was the cross-over release).
The way to handle this is:
1) try copying the entire VM folder (without exporting) and import to 2012 R2 (test this please).
2) Use 2012 to Import the export from 2008 R2, then upgrade to 2012 R2.

New blade servers

i have new b22 blade server ineed to install esxi on it ,but the admin for ucs for another team .can i use console to configure the the two server and islote the mangment and install esxi on the two blade .
i need help for this issue.

so you mean that you want to install ESXi on UCS B22 server but you are not the admin of the UCS. so you want to go attach keyboard and monitor to the blade directly to install ESXi on that server, is that the case?
Before you install the ESXi on the server, make sure the UCS admin has assigned a service profile to the server.
There are 2 ways for you to install ESXi on the server directly.
1. use the cable blew and attach it to the server, the connector supports USB/VGA/DB9 Serial port
http://www.cisco.com/en/US/docs/unified_computing/ucs/hw/blade-servers/B22.html#ID129
2. alternatively, you can ask the UCS admin to create a user for you on UCS which only allows accessing the KVM, then you can remotely log on to the UCS and install ESXi. the previliage required for this role is "Service Profile Server Oper"

Is it possible to use UCS Blade Servers in ACE Load Balancing

Hi all ,
Is it possible to use UCS Blade Servers in ACE Load Balancing ?? Please note that UCS Blade Servers are not connected directly to 6500 Switch where ACE Module installed .i am expecting a good suggestion from whether ACE or Switching Expert
Thanks in advance
Sanjeevi

There is nothing that would prevent you from loadbalancing the applications that run on UCS servers. ACE can loadbalance applications that are directly L2 attached (bridged or routed mode) or even servers that are multiple hops L3 hops away using one-armed mode with source nat. The key to this is that the return traffic from the server needs to make it back to the ACE.

Why the network link LED always off for all B200 blade servers? is it normal or heathy?

Hi Expert,
Why the network link LED always off for all B200 blade servers? is it normal or heathy? refer to the installation document, it means no active network connection. However, all these servers are up and running with netwirk connection. anyone could explain this?

Dinesh KIs the performance problem related to Oracle running on these servers?
If this is not the case, then you are on wrong forums.

Design/positioning for HP blade chassis into a Cisco infrastructure

We're involved in a DC infrastructure upgrade for a customer with several HP blade chassis, which all have Cisco 3020 switches.
In trying to figure out the new Nexus 5K/2K (FEX) design to upgrade them to Gigabit server access, they're questioning what the right replacement is for these TOR 3020s. Specifically:
Do the B22 FEX modules replace the 3020’s one for one, or are they advanced and provide the 4 ethernet connections for each blade with just one module?
Any advice or design ref/guidance for this question would be helpful, and thank you.

Hi Eric,
Rack mount or Blade servers from HP are both supported
any HP server or IBM server is supported as long as:
it is on the VMware HCL for the version of VMware vSphere ESXi required by UC.
it carries a CPU model supported by UC (described later in this policy).
it satisfies all other requirements of this policy
Otherwise, any HP/IBM model, generation, form factor (rack, blade) may be used.
From your link as well.
Cheers!

10g RAC on Blade Servers (HP C-Class)

All
Just wanted to know anyone's take on deployment of 10g RAC on blade servers -
Challenges, recommendations, etc. Anyone out there deployed a mission critical oltp application running RAC on blade servers?
Appreciate a response
Thanks - KP

Have several RAC blade clusters. Not using HP's blades though. The biggest one (12 nodes) is over 2 years old. The only h/w issue during that time as far as I can recall, was a power supply that blew. Vendor replaced and it was business as usual.
We are btw replacing all our HP boxes (old L classes mostly) with blade clusters. Given the stability and robustness of our big cluster, and that of the blades we're using for development, web servers and stand-alone database servers (running SE), we've decided to make this our standard h/w architecture. Of course, financially this receives a lot of noddy points from the bean counters. ;-)

Does BIA Blade servers suppot virtualization

Hi,
I have a question, would like to know if the BIA Blade servers support virtulization? Is it possible to implement BIA on the Blade servers with VMware installed on it, there by enabling virtualization?. Does the BIA blade servers support virtualization?
Thanks and Regards,
Archana

Hi Archana,
as Vitaliy already mentioned VMware is currently not supported. The reason therefore is relative easy. BWA is based on the TREX search engine and there is some interesting note which you should take a look (1303814 - TREX 7.1: Usage of TREX on Virtual Machines (VM))
The two reasons are why it also won´t be supported in near future:
1) TREX can be used in virtual environments for low-data-volume scenarios. Please note that the published sizing rules may become invalid. SAP has measured TREX performance losses up to 30%, depending on the virtualization solution. If TREX performance issues in virtual server environments arise, make sure you have configured your virtual machine correctly. Reserving memory (and in some cases CPU) are recommended to rule out shortness of resources on the virtualization host in case of resource contention. A detailed resource planning is absolutely mandatory!
2) TREX should be run on physical servers in high-load environments.
There is no note especially for BWA, but it´s not supported in cause of the low CPU load of the vmware HW. You won´t get support if you install your prod environment on VMware! If you take the chance you can setup your test environment on VMware, but normally you also won´t get support in case of an error. I think this depends on the philosophy of your company...

Jens

BI Acclerator Blade servers backups

Hi,
We have BIA running on HP blade servers and currently we have a procedue where they are taking
backup with some scripts and the scripts are generating some initiator files. ( which are some files on each blade server)
But can anybody provide me the info. how these initiator files are useful in backup / restoration of BIA.
The documentation of SAP shows a different procedure for backup/ restore.
BR,
DVRK

Not really sure what do you mean by "initiators"... in anycase if you are talking about BI Accelerator Backup Blades is a HA solution for enterprise search, so you should stick to the TREX backup/restore procedures IMO.

Docs on blade servers

Can someone please point me to where I can read up on how the switching module is working on blade servers?
Thanks.

If its IBM then you are better looking on the IBM site at their red papers.

Lync on Blade Servers supported?

Hi All,
is it supported to deploy Lync 2013 Frontend Servers on Blade Servers?
The reason for the question is: the Blade Servers use a Converged Network Adapter. As far as I know this is shared between multiple blade Servers. For Frontend Servers, TechNet recommends dedicated network interfaces with teaming.
The Blade servers also share a SAN and boot from there. Is this supported?
Many Thanks in Advance,
Hanno98

I would think that would be supported yes, if you think about it, it's really no different than a virtual environment which is also supported. Virtual servers share network adapters and boot from SAN storage. You're just dedicating resources
here. Recommended isn't always a must.

Using Essbase on Blade Servers

Hi,
What do you think about using Essbase (as part of EPM) on Blade Servers (eg. [HP BS|http://h18000.www1.hp.com/products/blades/components/matrix/main.html])
I need for your experience and examples of performance of this stack.

It being a blade or not a blade is not as relevant as processor speed, I/O, and memory. One thing to consider about blades is depending on your configuration it can limit memory.
In short a blade will be perfectly fine presuming it can scale to the level you need for your given design and number of users.
