Netbackup SAN Client Overview
Starting NBU 6.5 & above, Netbackup introduce SAN Client to provide fibre transport backup. This will reduce cost to the customer as before this server with huge data will only have Media server and its license more costly than SAN Client.
Setting Up NIC Speed, Duplex setting on RHEL
There's a tool call ethtool on Red Hat / Centos / Fedora
First install this tool
# up2date ethtool net-tools
Task: Get speed and other information for eth0
Type following command as root user:
# ethtool eth0
Output:
Settings for eth0:
Supported ports: [ TP MII ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
Supports auto-negotiation: Yes
Advertised link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
Advertised auto-negotiation: Yes
Speed: 100Mb/s
Duplex: Full
Port: MII
PHYAD: 32
Transceiver: internal
Auto-negotiation: on
Supports Wake-on: pumbg
Wake-on: d
Current message level: 0x00000007 (7)
Link detected: yes
Setup eth0 negotiated speed with ethtool
# ethtool -s eth0 speed 100 duplex full
# ethtool -s eth0 speed 10 duplex half
However, these settings are not permanent, if you reboot the system it will gone. To set it permanently, here is what you need to do:
To set the interface speed, duplex or auto negotiation on Linux system boot up (make settings permanent), you need edit /etc/sysconfig/network-scripts/ifcfg-eth0 file for eth0 interface. This file used by Red Hat enterprise Linux, Fedora core, Cent Os etc.
Open the file:
# vi /etc/sysconfig/network-scripts/ifcfg-eth0
Append following line:
ETHTOOL_OPTS="speed 100 duplex full autoneg off"
Save and close the system. It will set the eth0 device to 100Mbs, full duplex, with the auto negotiation off at boot time. You can simply restart the networking (it will disconnect all ssh or ftp session) or restart the server. Depend upon traffic and load it may take upto 1 minute to setup a new port speed:
# /etc/init.d/network restart
If you want 1000Mbs set line as follows:
ETHTOOL_OPTS="speed 1000 duplex full autoneg off"
Update: if above command failed to work for 1000Mbps use following command (see below in comment sections for discussion) :
ETHTOOL_OPTS="speed 1000 duplex full autoneg on"

This Applies to all managers
"The problem is the manager. He has a one-track relationship with players. Ask anyone here at Real Madrid. He can't change. You cannot go around just shouting at players. They need to feel special." -Jose Maurinho on Fabio Capello
Jose Maurinho is the special one, he is the best manager. He was not a good football player even he was dropped out of the squad, but he determine to be the best coach and now the only manager with PhD.

Malique feat. Tun Dr M - Layu
Malique feat. Tun Dr M - Layu
Sesungguhnya,
tidak ada yang lebih menyayat,
dari melihat bangsaku dijajah.
tidak ada yang lebih menyedihkan,
dari membiarkan bangsa semakin hilang…Aku lihat layu dalam melayu,
aku pasti bukan aku seorang sahaja yang nampak.
ada juga bercadang bertanya tuan punya,
tapi bercampur risau dengan tak tergamak,
nanti dikata tak bersyukur,
dikata tak sedar diri,
jadi aku menyendiri..memerhati..
dan akhirnya mengakui..yang kita sendiri,
membiarkan bunga raya melayu kekanan
dan dibiar bunga tak cantik mekar di kiri.Aku lihat layu dalam melayu,
tanah air kita yang punya
kita siram, kita baja,
tapi angin api kita lupa.Mereka merancang masa menjilat bangsa,
13 harimau bertukar menjadi mangsa,
kita lupa…nenek moyang kaya raya,
jangan sekali-kali digadai harta bendanya.Ku lihat layu dalam melayu…
Takkan melayu hilang di dunia..
Iya…tapi apa guna tak hilang di dunia,
kalau kewujudan tidak dirasa..
petah berbahasa, kudrat tak berjasa..
orang berbudi, kita hanya tau merasa..Selalu lari bila dirapat,
selalu malu bila soalan diaju;
Selalu segan memberi pendapat,
rela mengikut dari meneraju..Belum nyanyi sudah bersorak,
suka berjanji dalam borak..
Bukan kata tak ada otak,
cuma tak berfikir di luar kotak..Ku lihat layu dalam melayu…
Aku jadi sayu.
Bunga menangis, dia mendayu,
mahu jadi cantik tetapi ragu,
aku merayu..Bangunlah semula hidup kembali
jangan tunggu matahari mati
cepatlah mekar sebelum terlerai
perjuangan kita belum selesai…perjuangan kita belum selesai,
kerana hanya yang cekal dan tabah,
dapat membina mercu tanda bangsanya
yang berjaya….
