This document was written to force backups to use the 100Mbs interface cards on the Solstice Backup server and the Solstice Backup client
The Solaris FireEngine project is a high performance networking framework based on an IP classifier and vertical perimeters.
Any file under the Windows Temp folder is safe to delete. But that isn't the only place that temporary files are stored on Windows computers.
Veritas Cluster Server?s Low Latency Transport (LLT) protocol provides fast, kernel-to-kernel communication and monitors network connections.
Setting the size of a ZFS dataset can ensure an appropriate allocation of space configuration that contains multiple volumes to service different clients
Transferring files with scp isn't the quickest option, but if it's the only one there's a simple way to make it go a little quicker.
The maximum size of a single shared memory segment is specified by the shmmax (shm_max on Tru64 UNIX) kernel parameter.
If the system needs more memory resources and the RAM is full, inactive pages in memory are moved to the swap space.
This document provides the necessary steps to allow Backup Administrators to Migrate or Consolidate several Legato NetWorker servers.
There are two way to change block size to get quickly synchronized disks in mirrored system
Here, we've assembled 10 fast n' easy tweaks for any PC that break the factory mold and improve performance.
Using the tunesfs command you can modify certain parameters after creating the original file system without rebuilding the entire file system.
As the term has no exact definition it simply means reading multiple save streams at the same time but other definitions may be misread..
With Solstice Backup 6.1 a new parameter savegroup parallelism was introduced for load balancing reasons.
syslog is an important facility need in all enterprises. We as sysadmins look at syslogs as a critical source to troubleshoot performance issues
Host name resolution issues can cause the NetWorker server to become unresponsive or start very slowly.
We have many utilities like iostat, fsstat, sar, etc. in Solaris to identify disk I/O performance issues.
Several factors into performance calculations, including CPU speed, data storage devices, network limitations, and the volume of network traffic
bigasm is a NetWorker tool that can be used to test network throughput between clients and servers via expanding small files into larger files.

The Fast Reboot feature loads the kernel into memory and then switches to that kernel so that the reboot process occurs within seconds.
To obtain maximum efficiency and system utilisation, there are parameters that can be adjusted to tune the NetWorker environmen
Several factors affect a NetWorker server performance, including CPU, memory, paths and IO bandwidth and network bandwidth
Moving an index on a Windows NetWorker server must be performed using the UASM utility to prevent corruption of the index files.
In a nutshell moving an index on a UNIX based NetWorker server os achieved by using the UASM command. This procedure is not for the faint hearted!
Because ZFS uses kernel addressable memory, we need to make sure to allow enough system resources to take advantage of its capabilities
In ZFS, I/Os are scheduled similarly to how jobs are scheduled on CPUs.
Maximising data throughput under NetWorker using paralleliusm and target session settings
Media database scavenging is simply a way to force Legato NetWorker to rebuild the media database header files.
In a nuyshell, the K9Toolkit is a collection of tools written using the KStat library on a Solaris 9 server to help locate performance bottlenecks.
A simple post providing details of using sysperfstat from the K9 toolkit displaying utilisiation and saturation for CPU, memory, disk, etc.
