s8500 reliability

[btrain8]

is this statement true regarding standalone s8500/g650 that in a single server environment there can be no critical reliability? there's no benefit to having 2 ipsi's and 2 medpros unless you have dual servers is what i'm thinking.. is that valid?

One server = single point of failure = no critical reliability

As far as not needing 2 ipsi's, medpro's, etal it is certainly a business decision. If the org has decided that they can be down for the amount of time it takes to recover the S8500 then you can apply the same logic to the ipsi's, medpro's, etc. You do need to take into account that each component can have a different expected mean time to failure or probability of replacement.

I have a S8500 as an ESS server to my duplicated S8720s. I only got the one S8500 cuz I plan to add another one at another location in the future as a second ESS server.

But with 1 server and 1 network switch does having an ipsi in both g650A and B do any good. I know you can put an IPSI in if you want but is it going to be active for auto failover or it will be dormant as just a spare board basically?

There will be no failover since the S8500 has only one control network and you can only set 1 IPSI to S8500 so there is no sense installing dual IPSI. You're right it will be a spare board.

optionsleft, you can add a "dual NIC" card, to the S85XX, and with that, you can have Control Networks, however, you would really need to replicate the CN's from the Main site, via dark fiver technology, so usually, the IPSI's end up on the local LAN, because it routes. This usually what happens if a client has G650's at a remote location, that is only WAN connected, but not connected via dark fiber/layer 3 switch.

Having the 2nd IPSI does help, for example, if the LAN port locks up, or someone unplugs the IPSI A cable, in that case the 2nd IPSI, even if its on the same subnet would take over.
