VMware CPU Resources
Look at my VMware ESX Server CPU Resources.
- click here for bigger image.
As you can see from graph above, my VMware ESX Server running for more than 85% – 97% of CPU resources.
Basically I have 2 VMware ESX 3.5 running on top of Dell R900, Intel Xeon E7330 @2.4 Ghz processor and 128 RAM on each server. The CPU hungry incident happen when I did a vMotion about 40 VM guests from ESX 1 to another ESX 2 server for VMware ESX host patches update. Thanks god! My VM guest are still running without any issue and this is mixed of PRODUCTION and DEVELOPMENT servers.

How to add a raw mapping device on VMware
VMware ESX Server offers two choices for managing disk access in a virtual machine—VMware Virtual Machine File System (VMFS) and raw device mapping (RDM). It is very important to understand the I/O characteristics of these disk access management systems in order to choose the right access type for a particular application. Choosing the right disk access management method can be a key factor in achieving high system performance for enterprise-class applications.
Basically you can read few VMware RDM related guide from VMware such as: http://www.vmware.com/pdf/esx25_rawdevicemapping.pdf and http://www.vmware.com/resources/techresources/1040
I would like to share “How to add a raw mapping device on VMware” in my VMware ESX development box together with SuSE Linux Enterprise Server 9 VMware guest.
- Click on SLES 10 VMware guest in my Virtual Infrastructure Client
- Click Edit Setting
- Click Add
- Select Hard Disk
- Click Next
- Selecet Raw Device Mappings
- Click Next
- Select Target LUN
/vmfs/devices/disks/vmhba0:0:16:0
/vmfs/devices/disks/vmhba0:0:22:0 - Click Next
- Select Store with Virtual Machine OR Specify datastore
- Click Next
- Select Compatibility
- Choose physical (allow the guest operating system to access the hardware directly. Taking a snapshot of this virtual machine will not include this disk)
- For Virtual (it’s allow the virtual machine to use VMware snapshots and other advanced functionality
- Click Next
- Select Virtual Device Node -> SCSI (0:1)
- Click Next
- Ready to Complete
- Click Finish
- Click OK
Done!
As you can see from pictures show above, SLES 9 with 200G Raw Device Mapping Drive created.

Adding a new Hard Disk in SLES
For any system that can avoid downtime would be a great solution for system admin like me. I have a request from customer ask for additional 10G partition for /u03 due to emergency request in my SuSE Linux Enterprise Server running on top of VMware ESX host.
Adding a new hdd in VMware is pretty simple. Logon to VMware Infrastruce Client -> click edit setting in my SLES VMware guest and add new hard disk.
SSH as superuser into my SLES box and type:
rescan-scsi-bus.sh
That’s simple. I can view my new hard disk using command:
cat /proc/partitions
