Hello !
Recently I've build my NAS based on FreeNAS.
Here is my hardware:
Platform: HP MicroServer Gen8
CPU: Xeon E3-1230v2 3.3GHz
Memory: 16GB - DDR3 1600 MHz Kingston ECC
HDD: 4x 1TB
2 x 1TB WD Red (in mirror) - for personal archive (photos, videos)
1TB WD Green (stripe) - for movies (no any data on disk yet)
1TB WD Green (stripe) - for lab with VmWare (no any data on disk yet)
Applications (Plugins):
Transmission
Plex Media Server
miniDLNA
1. I noted that my memory was absorbed by system.
As you see from top here is 13GB of Wired memory.
I read some topics about memory and as I understand for my configuration I should follow "magic formula"
(8Gb + 4Gb) = 12 Gb memory that not exceed my 16Gb.
So, is it normal distribution of memory in my case ? because I have only 498M available memory...
2. Another question that I would like to use my FreeNAS as storage by iSCSI interface but just for tests.
As I understand it's not good idea because of some problem with ZFS and iSCSI and will have influence on performance system.
So what's you opinion about using iSCSI interface even just for tests ?
