(howto) Installation nas4free for network databases (ssd, onboard low cost NIC):

[onega23]

Installation nas4free for network databases (10-20 users)
tested version:

---------9.3.0.2 - Nayla (revision 1955):---------------

--------good hardware:--------------------
on "Intel Pro 1000 server adapters", nas4free 9.3 work fine,
with default settings, and with options "Enable tuning of some kernel variables",
but netbios names, for mounting shares in windows - don`t use.

--------low cost hardware:---------------------
if you use, low cost onboard network card, and have "panic" and "errors" in log
dont use netbios names, and use settings:

Services>CIFS\CMB:

Max Protocol = SMB3
Local Master Browser = YES
(warning, some MS SQL databases, run on windows7 pro\ent, don`t work in network, if on nas4free options "Local Master Browser = YES")
Time server = YES
Send Buffer Size = 64240
Receive Buffer Size = 64240
Enable large read/write = NO
Enable store DOS attributes = YES
Enable use sendfile = YES

Auxiliary parameters (CIFS\CMB):
Kernel oplocks = NO
Level2 oplocks = NO
Socket options = TCP_NODELAY IPTOS_LOWDELAY SO_KEEPALIVE
oplocks = NO
wins support = NO
os level = 250



system > advanced >
Enable tuning of some kernel variables = NO

system> advanced> sysctl.conf :
kern.maxfiles 32768
kern.maxfilesperproc 32768

(or 65536 if you need it)

-------------------Windows--------------------------

for stable file databases work, use only ip connection to server shares, don`t use names, don`t use netbios.

(192.168.25.2 ip adress Nas4free)
windows startup script example (bat file / cmd.file) :

ping localhost -n 5
net use T: /DELETE
net use R: /DELETE
net use O: /DELETE
net use M: /DELETE
ping localhost -n 5
net use T: \\192.168.25.2\Fbufer /y
net use R: \\192.168.25.2\lanusers /y
net use O: \\192.168.25.2\common /y
net use M: \\192.168.25.2\media /y



-----------result (onboard NIC realtek 1000mbit, SSD disk, after 2 houts of work 10 users)----------------
-no errors in log
-average file transfer (large files) - 700 mbit\sec
-average file transfer (small files on file share) - 250 files\sec
-speed of network file databases - very good for my (some speed, if use MS server 2008R2)
