Re: What volume files are not cached by default?
The prerequisity for FC is having system rock stable. At the same time the stability of FC mechanism is absolute must. In the end we talk about the potential data loss. For my personal usage "FC for DISKs" is way more suitable than "FC for volumes". (Partitioned HDD; C: for syste...

Re: What volume files are not cached by default?
I think I was already asking this... These files will afaik normally be cached... The question of pagefile makes a good usecase for having pagefile on another volume. (Or turning the pagefile off completely... if you have got enough memory and no program that would be screaming "if page files i...

Re: Performance statistics?
That's true. I'd expect the if "DeferredBlocks(Current)=0" then WriteBytes(Total)=DeferredUrgent + DeferredNormal. (Unless system was trying to write still the same blocks of data...)
I cannot confirm writes going around... (Since I don't use such toolings...)

Dynamic cache
Hi, Not sure if (/how easily) this is doable but it would be nice to be able to size L1 cache dynamically. (Especially because I don't know not sure how expensive is the opertion of (de)allocating an extra memory.) This is interesting especially in terms of cache growing (and potentially avoiding De...

IOPS throttling
Hi, I've been quite close to HW virtualization, terminal solutions (Terminal services, Citrix) or desktop virtualization (VmView, XenDesktop,...) etc. etc. The common feature of such solutions is that they run on virtual hardware. (ESX VMWare, Hyper V, XenServer etc.) These In many cases these solut...

Re: Performance statistics?
Well, not sure I follow. :) DeferredUrgent write: This occurs if there are too many data waiting write and cache is full. (If I am wrong I cannot imagine the different scenario for DeferredUrgent writes :) ) DeferredNormal: You said I was not correct. This would than mean that in current version the...

Re: Performance statistics?
Urgent: I understood it can happen earlier (In case there is a problem with cache size.) Normal: FC tries to write the data as soon as possible but only if disk subsystem is not busy. Con you confirm this? Recently I've spend some time by researching disk performance issues, counters and metrics... ...
