11. Instructions for iSCSI Cake cache.

There are two types of cache: server cache ("Cache size" under "Target setup") and client cache (cache under "Initiator setup").

Server cache - it is cache on iSCSI Cake server. iSCSI Cake will allocate an area from system memory for this cache. BTW, This cache is only for client reading.

Client cache - This is cache on the client, and it can be used for both read and write cache. To use this feature, you need to first install MS iSCSI Initiator, then install iSCSI Cake Client on the client computers.
Enable local cache - Only after you have installed iSCSI Cake Client, this option will be available. It's used for specifying the cache size on client. Then you need to select use "Memory cache" or "Disk cache".
Memory cache - If you select the "Memory cache", iSCSI Cake Client will allocate an area from system memory for this client cache.
Disk cache - If you select the "Disk cache", iSCSI Cake Client will create an folder as you specified (like C:\CakeCache) on the hard disk for this client cache.
Cache write only - If you select the "Cache write only", this client cache will be used for only write. If you do not select this option, this client cache will be used for both read and write.
