I have a system running
, and I intend to use a NetApp as its storage system. The application requires a throughput between the server and the storage 7000 disk IOPS (random IO sustained throughput with response time of 20 mili second and 16k block size).
How to make sure that I can achieve those figures?
Hi,
I want to tune my SUN servers for best performance. My servers are heavily loaded and used. They have Solaris 10. How to tune Kernel Parameters of solaris ? And How can I measue performance before changing parameters and after changing parameters ?
Please help
Thanks

Hello
Ive written 2 programs in shell and I need to compare their speed (Compile) against one another.
what methods could I go about doing this?
Is there a feature in shell do accommodate this? (2 Replies)
I am working on an application with some rather interesting build performance issues. If we build on Solaris/Linux x86/AMD64 the build is rather fast, but it takes more than five times as long on our Solaris Sparc servers (single-threaded builds on the workstations, but multi-threaded on the...

hi there, i'd like to know what exactly zpool's iostat (-v) output measure, especially the writes. Is it only the writes to the ZIL or all writes (including commmits) to the disks? if anyone knows, that'd be helpful roti (1 Reply)
Hi,
I have a simulation program which creates two threads and I would like to know if I can measure the time of each individual thread. Threads communicate (I use pthread to manage them) and I want to measure communication time. I found a solution with clock_gettime and CLOCK_THREAD_CPUTIME_ID... (32 Replies)
I have written a virtual HBA driver named "xmp_vhba". A scsi disk is attached on it. as shown below:
xmp_vhba, instance #0
disk, instance #11
But the performance became very bad when we read/write the scsi disk using the vdbench(a read/write io tool).
What is the reason? ... (7 Replies)
Hello guys,
I am doing a performance analysis on one of our psystem. Most of time I am using Nmon analyser to do my trend graph. But I can't find any help with it. We are interesting in the time spend by tasks in Aix run queue.
After looking the Aix documentation, I am pessimist to find any... (3 Replies)

netapp::snapshot
NetApp::Snapshot(3pm) User Contributed Perl Documentation NetApp::Snapshot(3pm)NAME
NetApp::Snapshot -- OO class for creating and managing snapshots
SYNOPSIS
use NetApp::Filer;
use NetApp::Snapshot;
my $filer = NetApp::Filer->new( .... );
DESCRIPTION
This class encapsulates a single NetApp snapshot, and provides methods for querying information about the snapshot, as well as methods for
managing it.
METHODS
get_parent
Returns the NetApp::Aggregate or NetApp::Volume object for the aggregate or volume for which object is a snapshot.
get_name
Returns a string representing the name of the snapshot.
get_date
Returns the date the snapshot was created.
get_used
Returns the percentage of space used by snapshot.
get_total
Returns the percentage of total space used by the snapshot.
get_snapshot_deltas
Returns an array of NetApp::Snapshot:Delta objects, each representing a single delta for this snapshot.
get_reclaimable
Returns the amount of reclaimable space, if the snapshot is deleted. Note that experimentally, this command has a lot of failure
scenarios, most of which are reasonable (there are a lot of cases where you can't query this data). Therefore, unlike most of the methods
in this API, it doesn't raise a fatal exception if it can't query the information, it simply generates warnings.
rename( $newname )
Renames the snapshot to the specified name.
restore( %args )
This method is an interface to the "snap restore" command. The argument syntax is:
$snapshot->restore(
type => 'vol' | 'file', # Defaults to vol
from_path => $from_path,
to_path => $to_path,
);
The 'type' argument maps to the -t CLI argument, and the 'to_path' argument maps to the -r CLI argument. Refer to the na_snap(1) man page,
and the "snap restore" documentation for further information.
