Controlling outbound bandwidth utilization by port
Among other things, I run an http server on my home DSL line
(6M/768kbit). The content includes several large image
galleries, and when certain crawlers hit our server w/
multiple large image uploads, we end up with large
ping time delays - sufficient to disrupt the kids''
on-line gaming. Attempts to control this with robots.txt
has not be very successful; Solaris IPQoS appears quite

X2200-M2
After the interesting revelations about the X2100 and it''s hot-swap abilities,
what are the abilities of the X2200-M2''s disk subsystem, and is ZFS going to
tickle any wierdness out of them?

Sparse file support in Java?
Does anyone know if there is support in Java for creating holes in a
sparse file (like one can do via fcntl(F_FREESP) in C)? Would like to
avoid writing JNI code if there is already support for this somewhere in
the JDK.

Z-Raid performance with Random reads/writes
Given a 1.6TB ZFS Z-Raid consisting 6 disks:
And a system that does an extreme amount of small /(<20K) /random reads
/(more than twice as many reads as writes) /
1) What performance gains, if any does Z-Raid offer over other RAID or
Large filesystem configurations?
2) What is any hindrance is Z-Raid to this configuration, given the
complete randomness and size of these accesses?

CAD application not working with zfs
Hello,
was use several cad applications and with one of those we have problems using zfs.
OS and hardware is SunOS 5.10 Generic_118855-36, Fire X4200, the cad application is catia v4.
There are several configuration and data files stored on the server and shared via nfs to solaris and aix clients. The application is crashing on the aix client except the server is sharing those files from a ufs

ZFS and memcntl(..., MC_SYNC, ...)
It wouldn''t be proper to start my first post here without congratulations
and thanks to the ZFS team for such an impressive piece of work.
Anyway, on to my query. I''ve been trying out ZFS, with a particular focus in
reducing latency in a specific application. This application has a fair
amount of random writing going on in the background (which, of course, ZFS
will make

Cheap ZFS homeserver.
So after toying around with some stuff a few months back I got bogged down and set this project aside for a while. Time to revisit. <BR><BR>
Looking around there still is not a good "these cards/motherboards" work list. the HCL is hardly ever updated, and its far more geared towards business use than hobbyist/home use. So bearing all of that in mind I will need the

DIF means?
Hi,
In Solairs Dtrace User Guide, page 193, it lists the arguments of ERROR probe.
One of these arguments is arg3, it is explained as "The DIF offset
into that action or -1 if not applicable".
Then what does the abbr. DIF mean?

lots of small, twisty files that all look the same
A customer has a zpool where their spectral analysis applications create a ton (millions?) of very small files that are typically 1858 bytes in length. They''re using ZFS because UFS consistently runs out of inodes. I''m assuming that ZFS aggregates these little files into recordsize (128K?) blobs for writes. This seems to go reasonably well amazingly enough. Reads are a

I was trying to join a samba DC to an existing AD. But it failed when I used the command ‘samba-tool domain join euler.huawei.com DC ‘ to join it to the domain. Here’s the log:

Oracle on ZFS vs. UFS
Hi,
I''m preparing a personal TPC-H benchmark. The goal is not to measure or
optimize the database performance, but to compare ZFS to UFS in similar
configurations.
At the moment I''m preparing the tests at home. The test setup is as
follows:
. Solaris snv_37
. 2 x AMD Opteron 252
. 4 GB RAM
. 2 x 80 GB ST380817AS
. Oracle 10gR2 (small SGA (320m))
The disks also contain the OS

Available free memory.
Hi,
Can I use DTrace to determine memory status?
1.Total Physical Memory, Used Memory.
2.Total Swap Space and Used Swap Space.
I did find few DTrace scripts but had too much
in them and I am unable to chop off unwanted
lines of code due to lack of knowledge.
It will be very helpful if some one can share
the piece of code that serves my purpose as
mentioned above.
Regards,
Ramesh.

dtrace & MPI program
Hi all:
Can dtrace trouble-shoot the MPI porgrams (HPC programs)?
Does there exist an extension on dtrace to debug MPI program?
If exist, then where can I find the how-to documentations?
Thanks in advance?

gzip compression throttles system?
I just had a quick play with gzip compression on a filesystem and the
result was the machine grinding to a halt while copying some large
(.wav) files to it from another filesystem in the same pool.
The system became very unresponsive, taking several seconds to echo
keystrokes. The box is a maxed out AMD QuadFX, so it should have plenty
of grunt for this.
Comments?

Is there any performance problem with hard links in ZFS?
Is there any performance problem with hard links in ZFS?
I have a large storage. There will be near 50000 hard links for every file. Is it ok for ZFS? May be some problems with snapshots(every 30 minutes there will be a snapshot creating)? What about difference in speed while working with 50000 hardlinks or 50000 different files?
ps: It would be very useful if you give me some links about

deSolve: Problem solving ODE including modulo-operator
I have a problem integrating the 'standard map' (
http://en.wikipedia.org/wiki/Standard_map
http://en.wikipedia.org/wiki/Standard_map ) with deSolve:
By using the modulo-operator '%%' with 2*pi in the ODEs (standardmap1), the
resulting values of P and Theta, should not be greater than 2pi. Because
this was not the case, i was thinking that the function 'ode' has some
