Dual power on 6510, but not on the HA100?

suggestion

#1

The lack of dual power on the HA100 is very surprising, since the 6510 is equipped both with dual power AND POE support. That basically kills the dual-power redundancy inherent on the 6510.


#2

That is a great point…

This suggestion has been noted.

+1 …Agreed!

High Availability - true means fail over, but why just 1 x power supply?

In a traditional Computer High Availability sense, you have double everything.

Dual CPU - in case a CPU fails you have the other
Dual Power - in case one UPS dies the other supports
Dual sets of Ram - so if one set fails the others are still available
Raid 5 or 10 - for keeping the data available over multiple Hard Drives

Did I miss anything?

It simply not needed ?
IF HA break then calls are still forwarded to 1 UCM.
If you suspect 1 HA psu + 2 UCM PSU go down in 1 malfunction then you clearly do not have correct protection.

I think 2 PSU can be better but in term of Availability it not make any real difference for correct implementation.

Set is 1HA + 2 UCM so you have everything double and HA is extra system.
