Question :
Hello Sun-Managers
I have a Sun E450 Enterprise machine
I have 4 internal hard disks of 4.1 GB
[ Seagate Barracuda ST34371WC ]
and one Power Supply Unit
I need to add one more 4.1GB Disk
I understand that I need to buy a 8 bay expansion unit
to add the new hard disk.
Do I need to have another power supply unit for this.
I also need to have one more PS unit for redundancy.
My question is whether I need a total of 3 PS units
(1 for redundancy) when I add in a new hard disk.
Thanks
Aaj
Answer and Summary :
Many Managers replied and most of them said when a 8 bay
expansion unit is added for the 5th disk, you need to have another PS
unit. and for Redundancy one more.
Some managers told that 2 may be enough, and few of them suggested to
look into the E450 Owners' hand book or some other manual like that
(which I don't have). There is a chapter in that manual which explains
how to calculate the number of Power supply units needed for the system.
Thanks to all Managers who responded.
Regards
Aaj
