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

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...

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.

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.

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,
Rob Moss

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.

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?

Hi Tabish,
How many times do you have to open this same topic?
In my opinion, this is your THIRD thread for the same topic.

Cisco wave virtual blade disk size shrunk, unable to restore vblade

Hi All,
I applied the workaround listed by Cisco for bug CSCsy47235 on our wave device, which is also mentioned numerous times on the forum here, to do: disk delete-data-partitions and reload. after the reload, we are unable to restore the backed up blade image file, we get the error: '162GiB image is too large! 160GiB image is allowed'. when i try to create a virtual blade, the maximum disk size has reduced from 162GB(before the change) to 160GB(after the change).
Any idea or solutions would be greatly appreciated.
Thank you
Jack

Hi Tim,
These disk size are fixed and cannot be altered, hence you will not be able to allocate the unused cifs/dre to vb disk or the unused vb disk for cifs and dre.
There is no way to increase this as well, as most of these are determined whne you load the software and the partition table is fixed. Hence you wont find any maximum numbers. 32 gb is what you will get as part of wave 274 and wave 474 and that is the maximum disk space. You can split this across two virual blades , allocating them 16gb each , but however the total still cannot exceed the maximum of 32gb for all the virual machines.

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. ;-)

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.

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.

Poor network when create virtual switch in hyper-v 2012

Hello,
i installed on DELL R620 windows server 2012 STD and add the hyper-v role
when i created a virtual switch , the speed of network in the HOST( the server itself) is ver poor ( copy file from fileserver is 300Kbs)
when i remove the virtual switch , the speed of the network is better( copy file from fileserver is 10-20Mbps)
i spoke with DELL support center , and after check up , no problem has found.
i tried all the chnges with the offload checksum etc but nothing helped
Please your comment about this issue
Thanks
Dotan

Need some additional information
Which Team type are you utilizing?
Which Raid Controller are you using on the hosts?
I would suggest you try this as well while its specific to 10Gb CNA's it can help with 1Gb in some cases. SMB
FILE COPY PERFORMANCE
Also utilizing the low latency Bios settings can often offer additional NIC performance

Oracle 10g IO perfomance on vmware virtual machine

Hi Friends,
I am facing perfomance issue on oracle10g 64bit, installed on rhel5.3 64bit on a vmware virtual machine because of disk IO.
While taking DB backup using netbackup I can see the datatransfer speed comes up to 100 Mbps.
But when oracle IO requests comes it is not going more than 30 Mbps.
And the CPU IO wait remains same as on both of the time. (20% to 40%)
Please help.
Regards,
Nayagan

Could you verify this behaviour outside a VMware virtual machine?
If yes, then please open an SR on Metalink to let support diagnose.
Provide an RDA, AWR snapshot if you have licensed the Diagnistic Pack - if not than provide STATSPACK snapshots.
Sorry - but this is a database upgrade forum :-)

Connceting FMS over RTMPT resulted in poor perfomance of whole application

Hi,
We are connecting to FMS 3.5.7 behind the firewall through rtmpt and we have very poor performance over whole application even though we are not playing video in the application.My question is does the rtmpt use port 80 over http eventhough when we dont play video in the application.does it effect performance of whole application when connected through rtmpt?.
Can you pleae suggest me the solution to imporve my perfomance of the applciation when atleast not playing video in the applicaiton.Please suggest some changes..

Hi,
If you are accessing application from outside the firewall It cause problem in continuing the connection with FMS. you can see through wireshark, there will be reconnection very frequently. So, it is better to use rtmps for better performance.
