Hi all, I have a simple question in mind. I want to introduce client side caching in any network or cluster file system. The caches are in-memory cache not secondary cache as in AFS but as sprite. My question is all the cache is in kernel space and if large file happens to mmap or read/write say 2 GB etc. What would be consequence if there is great limit on my cache. We know kernel space virtual address are from 3GB to 4GB. If i start allocating cache block as soon as i'm getting file from storage node and if my cache size is 5GB then this will hang the system as kernel cant have that much addresses refer to. And in that case we need either CPU to address 64 bit or something like that. But even then there is limit on cacheing the file data. So how much shall i keep my cache size to have best performance. I hope i'm pretty clear in what i asked? Thanks Prasanna __________________________________ Do you Yahoo!? Yahoo! Mail - Easier than ever with enhanced search.
