AFP Slow

Over the weekend, we moved a storage array from one server to a new server.
Both servers are running OES current support pack (5). All seemed fine,
until
this morning when the MAC users came in. AFP connections are very slow.
The connections are slow wether we are connecting to the drive array that
was transferred to the new server, or the boot array that is internal to the
server. There are not that many settings for AFP that I am aware of, so I
don't know where to look.

If we connect via a SMB connections, it is close to normal, but this causes
other issues and is not a long term fix.


I can read/write to the server just fine with a PC, so it doesn't sound like
a network congestion or NIC driver issue. There is also no difference where
I read or write to on the new server (old or new arrays.) I am looking
through the knowledge base right now, but can not find anything yet.

Does anyone have a suggestion?

Thanks
Ben

Re: AFP Slow

You could try nw65sp5upd1 and n65nss5b, which updates AFPTCP.

In what way is it slow? Copying files to the server? From? Both? Running
apps from the server volumes? Apps opening data files on the server
volumes? Browsing the volumes? Authenticating?

What lan driver, date and version, on the server? Check that it, and the
switch port it's plugged into, are both on autonegotiate, not hard-set
to 100FD or anything else.

Re: AFP Slow

Currently we are running the following NIC driver from the latest HP
Proliant Support Pack.

Q57.LAN 9.42 May 10 2006

In addition to NW6.5 SP5 I have also installed

HP PSP 7.60
Ethertsm and MSM update for NW6.5 TID2973525
nw65sp5upd1
n65nss5b

We are having issues opening/copying files from the server to a MAC using
AFP. Uploading files to the server is just fine. In TCPCON, I just noticed
that the Retransmitted count in Statistics-TCP stedily climbs when
opening/copying from the server to a MAC. The value goes up 1-13 per
second. When working with PCs the value pretty much doesn't move.

It does not appear to be a speed/duplex mis-match either. The server is
connected at 1000/Full, which is what it should be at. Also the MACs look
good as well.

Lastly, I can transfer files back and forth from the old server to a MAC
without a problem.

Any other suggestions?

Re: AFP Slow

Sorry, I made a mistake! In the last post, I stated that the retrasmitted
value stays the same when connected with a PC which is incorrect. I was
looking at the wrong server console when transferring to a PC. The
retransmitted value jumps VERY FAST when transferring a large file to a PC.

So now I guess I have to suspect a networking issue. The only problem is I
already checked the speed/duplex, updated the driver, etc.

Any suggestions would be appreciated

Re: AFP Slow

I would go for a faulty nic in the server, wrong settings on the
switch/router, a faulty router, and a bad cable, in that order.

Re: AFP Slow

First off, thanks for all of the suggestions. I must also apologize again,
because the retransmission counter only went up for communication from the
Server to a MAC. At one point, I thought the counter was going up for
Server to PC communication too, but I was stressed and became confused.

Anyways, we ended up trying cables, different ports on the switch, different
switches, etc. Eventually I opted to force the Server NIC to 100/FDX
instead of Auto (1000/FDX.) Once I made that change, the problem speed was
much faster, but the problem not solved. The retransmission rate was still
going up at the same rate only for AFP. AFP from the Server to the MAC
still was not at "normal' speed either.

At that point, I suspected that something was funny with the driver. We had
tried the past couple versions of the driver that was available from HP and
the problem continued. All other communication to and from the server was
fine at 1000/FDX, just not AFP from the Server to a MAC. The server has two
embeded NICs, and we were only using one. Of course the next step was to
try the other embedded NIC, which had the same problems.

Next, we installed a Intel Pro 1000MT Server NIC. Using all or the original
network equipment (cables, switches, etc.) everything works flawlessly.

At this point, I am glad it is working. We have other identical servers
that are not put into production yet, but now I know what to expect. I let
HP know the problems I am having and await a response...

Just in case anyone is wondering, the server I am having issues with is a HP
Proliant DL380 G4.

Thanks for all the help,
Ben

Re: AFP Slow

The Broadcom cards, or more correctly their drivers (B57, Q57), are a
perennial source of problems, but this one is a new one for me.
