The Raspberry Pi is a 25$ credit-card sized computer that plugs into your TV and a keyboard. It’s a capable little PC which can be used for many of the things that your desktop PC does, like spreadsheets, word-processing and games. It also plays high-definition video. Now the VMware View Client 5.0 is working on RaspberryPi, SSL security options is ok also auth via RSA. PCoIP protocol seem not working at the moment, just the RDP.

This video will give you an introduction to the View Storage Accelerator, a caching feature that can reduce storage costs and improve performance in VMware View.

The Storage Accelerator is made up of two components. The first is a per VMDK digest file and the second is a global cache. The per VMDK digest file has a mapping for disk block number to hash value and the global cache has a mapping for hash value to actual data. The global cache is a reserved area of memory on the ESXi hosts.

 It is an in-memory dedupe cache that caches data based on the content hash of a disk block. When the VM issues a read request, we first use the digest file to get the hash value for a block and then consult the global cache to see if the block is in cached. Metadata for the digest file is maintained in memory. If there is hit, we go fetch the data from cache; if there is a miss, we go fetch the data from disk.
