Ok I’m happy for people to play with my new app known as “Resource Pool Scheduler” aka “RPS”. You can download RPS from here >

Resource Pool Scheduler 1.2 is an application that is managed with a GUI but runs a service and is used to periodically change the settings of a vSphere Resource Pool for example:
You may require to divert the CPU share allocation of a resource pool to a resource pool which is used for backup servers at 7pm and then revert the CPU share allocation back to how it was at 7am. This is useful to give the backup servers priority between the hours of 7pm and 7am.

Ok so I developed a tool to allow you to create your own webpage plugins in the vSphere client. For example you create a tabbed plugin so you can include a management portable like VMware’s View Admin Console or maybe your favourite blog site.
Plugin Wizard for vSphere (1005 downloads) allows you to register websites or web portals within your vCenter VI Client. It’s a 2 step process. Step1 involves creating an xml which is the visual configuration and contains the actual url link to plugin your website. Step2. Requires you to register this plugin within the VI SDK.
The result is a tabbed view of your plugin:
OK here’s a cheap way to speed up VMware Workstation VMs whilst limited by the amount of memory your computer can take or even the 4GB limit posed by 32bit Windows operating systems.
The answer is simple providing you use Vista or Windows 7: Purchase a 4GB ReadyBoost USB stick.
ReadyBoost is a component of Microsoft Windows, first introduced with Windows Vista in 2006 and also included with Windows 7. It works by using flash memory, USB 2.0 drive, SD card, CompactFlash or any kind of portable flash mass storage system as a drive for disk cache and virtual memory.
Using ReadyBoost-capable flash memory for caching allows Windows Vista/7 to service random disk reads with performance that is typically 80-100 times faster than random reads from traditional hard drives. This caching applies to all disk content, not just the page file or system DLLs. Flash devices typically are slower than a hard disk for sequential I/O so, to maximize performance, ReadyBoost includes logic that recognizes large, sequential read requests and has the hard disk service these requests.
When a compatible device is plugged in, the Windows AutoPlay dialog offers an additional option to use the flash drive to speed up the system; an additional “ReadyBoost” tab is added to the drive’s properties dialog where the amount of space to be used can be configured. 250 MB to 4 GB of flash memory can be assigned. ReadyBoost encrypts, with AES-128, and compresses all data that is placed on the flash device; Microsoft has stated that a 2:1 compression ratio is typical, so that a 4 GB cache could contain upwards of 8 GB of data.
Under the preferences/memory settings of VMware Workstation make sure you select “Allow some virtual memory to be swapped”. Normally to enhance performance in VMware Workstation you’d select “Fit all virtual memory in reserved host RAM” but when using Readyboost swapping occurs a lot faster and it means we get the added bonus of additional memory to use. So not only is it quicker we can now fire up more VMs.
