Does anyone know if its possible to purchase the Business Edition as software only option ?
If yes, is there an approved HP or IBM server which is equivalent to the MCS 7828 ?
Thanking you in advance for any assistance with this.
The answer to your question is no.
"Note that the Cisco MCS 7816 and MCS 7828 do not have a software-only supported option"
From the following links -
HP or IBM equivalent are available for 7825/35/45 only.
