Hello,
I'm not sure if my email was posted on the list samba at lists.samba.org so
I post it again. If it was already posted I apologize.

Hello,
I'm planning to use samba 4 on debian jessie. In my environment are
approx. 50 clients (windows 7). Maybe later some linux mint clients as
well.... also about 5 hp Network printers....
Now i' m not quite sure which hardware I should use for samba 4 primary
dc and recommended secondary dc and file server which all should reside
on different hardware as recommended. Should I use stronger hardware for
the file server? What about the backups? Where should I store the backups?
I got the following hardware:
2 server PCs with the following configuration - they are exactly the
same Hardware:
4 disk drives with 1000gb each (sata), at the moment confugured in raid
1, 4gb Ram, about 6 years old
1 server PC with 1 disk drive with 100gb (still ide), 1gb Ram, about 10
years old
network is max. 100mbit/s...
Where would you install primary dc, secondary dc and file server? Where
the backup?
Thanx in advance for recommendations...
KR, jolly
Also I' m able to configure samba 4 on debian wheezy. If there are
special things to consider on debian jessie and you know tutorials I'm
happy about links.... do you use sernet packages samba 4 on debian
jessie or just samba 4 that comes with Debian jessie?

Where > the backup?If I count this right, this are 3 servers for 4 purposes (2 DCs, 1 fileserver, 1 backupserver). You should not put your backups on one of these 3 servers. What if this one gets lost? If it should be really cheap, put it at least on some external media. For a production environment you should use an additional host. Don't expect much CPU usage/IO/network traffic on the DCs. Your network is quite small, so I'm sure the 1 GB machine is fine for that. However you should think about putting everything on RAID. For the fileserver it depents on your needs. Usually you don't require much RAM in that machines. CPU usage is mostly also low in networks not transfering all the time hundreds of GB to the host. Maybe a good questions is: What is the current purpose of this hosts. Or what hardware are you currently using for the file-/backup server and for the host controlling your domain (if you have one)?> Also I' m able to configure samba 4 on debian wheezy.

I have a very small Samba4 system that supports my W7 clients. So small, in fact, that I have only one DC (right now.) My DC is a 32-bit Pentium4 processor (512Mb RAM, 60Gb hdd), small form factor case, I got lucky and found for cheap$$. My member server is a Intel DuoCore PC with RAID 1 (mdadm) hard drives mirrored running on Debian 7.8.0. And my backup machine is a seperate (does only backup) QuadCore, 2Gb RAM, with OS on 60Gb hdd and two 1Tb hdd's that store the data. All these connected to a 1 Gb LAN. If "I" were supporting 50 W7 clients then "I" might seriously consider two DC's. In the unlikely event that a system loose it's single DC, the W7 clients are virtually useless without the Samba4 backend. I don't think you want your office workers staring at you while you restore your lone DC. Bottom line . . . you probably should consider four separate machines, 2 DC's, 1 member, and 1 backup. (Backups . . . need to get an image off site in the event of a catastrophic disaster . . . tornado, flood, fire, etc. . . but you have probably thought about this already.) (I have noticed recently, online, off-lease Dells, Lenovo's, HP's, and others small form factor CoreDuo processor PC's for less than $100usd. Ad's mention 32-bit software but when you look up the processor spec details they are 64-bit processors running 32-bit software . . . these are good deals!! I cannot remember if Debian 8 is 64-bit only but, CentOS 7 is 64-bit only, now requiring minimum 512 Mb RAM to install. I know that for a fact.) There are a lot of alternative variations your system can evolve into. Mine is just one **example**. Others may have a different ideas . . . good luck. --- _______________________________ Bob Wooden of Donelson Trophy 615.885.2846 www.donelsontrophy.com [2] "Everyone deserves an award!!"
