Hi,

I have a VM thats running ESXi and has 15K hard drives in. There are 4 VM on the machine as they are only low loads.

I have notices that the data transfer is painfully slow (1.88 MB/S) This is just cutting data from one folder to another on the same VM.

The Tin is a Dell Poweredge 2950.

I have checked the CPU and RAM and its not bottling out there so am a little lost.

What should I be looking for..

New to ESXi

THanks

Hi,

Thanks for the replys:

I have a Perc6/i card

6 Drives with two as HS

I have looked in the PERC 6/i bios and have selected the Advanced check box but it keeps defaulting to unchecked even though I click apply.

that firmware and bios is very old; latest is 6.3.3-0002 and bios 2.7
suggest updating both and looking at drive firmware also

Dell Server BIOS PowerEdge PE2950 Version 2.7.0

you can install the open manage tools for esx
didn't specify esx version; this bundle is for 5.1

Dell OpenManageServer Administrator vSphere Installation Bundle (VIB) for ESXi 5.1
http://www.dell.com/support/drivers/us/en/04/DriverDetails/Product/poweredge-2950?driverId=WHYNF&osCode=XI51&fileId=3324828011&languageCode=EN&categoryId=SM

you can run open manage on a windows system and connect to the esx host and view all hardware components from there.  storage will be near the bottom left as you drill down through the controller and connectors you will see the drives and the firmware will be displayed

for the bios and controller, you will have to boot on a linux/dos boot media and install from there since you can't do those updates from esx console as you would normally through windows and linux

Hi,

I have down the following:

1. Login to the system running VMware Vsphere Client or vCenter-Server
2. Bring the intended ESXi host into Maintenance Mode

But cannot find/do this:

3. For VUM based installs, Select the ESXi host. Click Update Manager, Admin view, Patch Repository, Import Patches and follow the online instructions to upload the patch successfully. The offline bundle is displayed.
4. For other install methods, unzip the offline bundle to extract the vib and metadata.zip. Use the vib to install Server Administrator software on the desired ESXi host
