NFS / DAS / SAN / NAS - Which is best?
i've used only NFS and as many already found out, it can be or rather i should say, it is very unreliable.
based on the collective experiences of the members on this board, i would really appreciate it if someone can tell me what the next best file sharing method is?
is it DAS? SAN? NAS?
I'd like to know what the most respected, reliable, well tested method is so i can encourage my management to budget for it.
thank you.
btw, i expect to mount whichever method comes out ontop on all types of UNIX hosts (linux, aix, sunos, hpux).

Hi everyone,
I wonder if I can canvas any opinions or thoughts (good or bad) on SAN attaching a SUN V880/490 to an EMC Clarion SAN?
At the moment the 880 is using 12 internal FC-AL disks as a db server and seems to be doing a pretty good job. It is not I/O, CPU or Memory constrained and the... (2 Replies)

Hi,
I am having some NFS directory consistency problems with the below setup on a local (192.) network:

radtest
RADTEST(1) FreeRADIUS Daemon RADTEST(1)
NAME
radtest - send packets to a RADIUS server, show reply
SYNOPSIS
radtest [-d raddb_directory] [-t pap/chap/mschap] [-x ] [-4 ] [-6 ] user password radius-server nas-port-number secret [ppphint] [nasname]
DESCRIPTION
radtest is a frontend to radclient(1). It generates a list of attribute/value pairs based on the command line arguments, and feeds these
into radclient. It's a fast and convenient way to test a radius server.
OPTIONS
-d raddb_directory
The directory that contains the RADIUS dictionary files. Defaults to /etc/raddb.
-t pap/chap/mschap/eap-md5
Choose the authentiction method to use. e.g. "-t pap", "-t chap", "-t mschap", or "-t eap-md5",. Defaults to "pap". Using EAP-MD5
requires that the "radeapclient" program is installed.
-x Enables debugging output for the RADIUS client.
-4 Use NAS-IP-Address for the NAS address (default)
-6 Use NAS-IPv6-Address for the NAS address (default)
user Username to send.
password
Password of the user.
radius-server
Hostname or IP address of the radius server. Optionally, you may specify a port by appending :port
nas-port-number
The value of the NAS-Port attribute. Is an integer between 0 and 2^31, and it really doesn't matter what you put here. 10 will do
fine.
secret The shared secret for this client.
ppphint
If you put an integer > 0 here, radtest (or actually radclient) will add the attribute Framed-Protocol = PPP to the request packet.
nasname
If present, this will be resolved to an IP address and added to the request packet as the NAS-IP-Address attribute. If you don't
specify it, the local hostname of the system will be used.

radiusd(8), radclient(1).
