Iscsi 10Gb and performance

Fast Ethernet is 100Mb/s throughput

12 MB/s speed (theorhetical)

Gig Ethernet is 1000Mb/s throughput

125 MB/s speed (theorhetical)

10 Gig Ethernet is 10,000Mb/s throughput

1250 MB/s speed (theorhetical)

Pratically on  ISCSI 10 Gig the throughput is 300-500 MBps it is very good.

Tivoli Storage Manager Operations Center

Finalmente, come già invocato in alcuni mie post precendeti, IBM hai in test la nuova GUI per TSM.
A molti non sfuggirà la somiglianza con l'interfaccia del SVC e V7000 (GUI eredita dall'XIV)
Aspettando ulteriore info ecco un video  di fine Febbraio:

ANS1715E A filespace already exists for VM

Tivoli storage manager 6.3.2 and virtual enviroment 6.3.2

ANS1715E A filespace already exists for VM (Virtual machine name), but with a different VM uuid (UUID) than the current one (UUID).

Because the vm is cloned or restored from backup

Add to opt file :

testflag VMBACKUP_UPDATE_UUID

Command to start TSM GUI from client windows with different opt file

dsm -optfile=<path and filename of desired options file>". 

SVC and Global Mirror Whit Change Volumes

In recent days I have configured and activated LBGM I read this redbook

SAN Volume Controller and Storwize V7000 Replication Family Services

and the implementation is easy. Now I have a replica every 12H

To check the last volume main change that has finished copying to the secondary site:
- Connect to SVC using CLI
- type :
IBM_2145:SVCMO:admin>lsrcconsistgrp PAUL

 and Freeze_time is the timestamp of the last completed copying
freeze_time 2012/12/18/05/02/22
