Collection of metadevices which have their own metadb
/var/adm directory contains Administration information

/var/sadm directory contains all the package related
we can create 8192 non global zones within global zone but
in realtime environment only at max of 10 to 15 is possible
We can use dladm command to change network interface
property in Solaris
In this example below maximum bandwidth of link is set to
$ dladm set-linkprop -p maxbw=2m e1000g0
Similarly if you want to set the link to full duplex
$ dladm set-linkprop -p duplex=full e1000g0
Advantages of Disksuite
Solstice disk suite provides three major functionalities :
1. Over come the disk size limitation by providing for
multiple disk slices to form a bigger volume.
2. Fault Tolerance by allowing mirroring of data from one
disk to another
and keeping parity
information in RAID5.
3. Performance enhancement by allowing spreading the data
multiple disks .
There are two ways to add swap in Sun Server(i.e. Sun
Solaris) as below;
1. Make a partion at availbale free disk of required swap
size and then make an entry in /etc/vfstab file. After that
run the command #swapadd /dev/dsk/cXtXdXsX or give the
reconfiguration reboot to the Server.
2. Instead of making partion you can create make a file of
required swap size with the help of #mkfile <size>
<filename> command and after that make an entry
in /etc/vfstab and follow rest of steps mention in point
Zones: A zone is a virtual operating system abstraction
that provides a secured environment where applications
run.The applications are protected from each other to
provide software fault isolation.
Container: zone + resource management
The ability to control resource usage for processes,task
and zones.Resources can be CPU level,RAM,virtual
memory,Kernel level tables etc.
