Does anyone know of a tool that I can use for IO performance reporting. My need is for a tool where I can specify the type of IO workload and a specific number of IO's for the workloads. Most tools I have found run test to show me how many IOPS and MB/s I can get at a given workload. My need...

I didn't read this post before today and I have some general things to say. Regardless of what disksystem you have attached to your SAN you will in some cases end in a situation where the number of HDA's is a factor. But when you talk about read you have to take into account that a good...

In Windows 2008 there is a Datacenter Edition and a Itanium Edition. Mostly I think it is because M$ doesn't want to support all features from Datacenter Edition under Itanium. http://www.microsoft.com/windowsserver2008/en/us/differentiated-features.aspx /johnny

As I remember the L180 it comes with HVD SCSI interface and/or FC interface. At least that is what I have been using on L180 libraries in the past. Have never used DLT7000 in an L180, but you could try to hook up each drive alone to the server and see if you will be able to see the drives from...

As I remember the licens for a 16 port Brocadde switch you just need a full fabric licens. One of the features I remember from the extended licens is that you can bundle/channel several ports together. What SFP's you need depend on your fibers, but since you say it is dark fiber you will need...

If we go with the Itanium setup we will use a couple of HP Integrity rx8640 Server to start with. There are not that big, but also not that expensive. And since Windows 2008 Itanium will only support 32 CPU's it is a good choise except for the maximum of 512 GB memory We use the HP Integrity...

I don't think cost is a big issue for Windows. USD 2.500 per CPU isn't much compared to the cost of MS SQL-Server. The information Microsoft give isn't very helpful. I was thinking more in the direction if someone has expirience in what the strength and weakness is for the 2 platforms? Is...

Thank you But I was thinking more about what others have expirienced with those 2 options so that I can come a little closer to what is the best option for us. /johnny

Hi We are planning for a database server setup where we want to use Windows 2008 Datacenter or Windows 2008 Itanium as the platform for MS-SQL Server 2005 Does anyone have some advice on what the strength and weakness is for the 2 platforms? /johnny

Would that have anything to do with my bandwith use? (except just in general make it slower) On Netbackup (where I come from) you have a setting that can limit the bandwith used (like linit it to 256Kbit/s) /johnny

Hi Is there a way to throttle how much bandwith a TSM client will use for a backup and a restore? I have to restore a remote server and can't use all bandwith for the restore alone. And restore time isn't that big a problem. Clients are Novell and Windows. /johnny

Thanks The servers we will run the tests on are anything from a small HP blade, IBM blades, HP8640r and HP SuperDomes and what else we have standing around. In generel all servers use Emulex HBA's. I also need to disable read caching, not only write caching. /johnny

Hi We are running some performance tests on some of our SAN fabrics and some of the SAN attached disksystems. To get the right picture we need to make sure that Windows doesn't do any filesystem caching. Can anyone tell me how to disable Windows Filesystem caching? /johnny

Hi Jens If I remember right the old VSM and SVA9500 are using standard IBM SSA drives. So I would try to get my hands on a drive like that. I found this link http://www.ultratec.co.uk/stocklists/Search-ResShopnew.asp?model=DCHC09C The 9 GB model is at the bottom. But I have never tried to...
