Hello,
We have a customer Hongkong Bank, who is using a SNA microserver DEMSA
for access to an IBM-compatible mainframe :
VAX 7820
|
---------------------------------
|
DEMSA
|
X.25
|
IBM Mainframe
On the VAX, VMS 5.52 is used, and also SNA VMS and SNA LU6.2 on VMS.
They are considering to phase out the DEMSA box and replace it by
a gateway machine, maybe a small Alphaserver.
But they are concerned about the performance of an Alpha-based gateway
compared to DEMSA. Do we have any figures to show them ?
Also, would someone like to abvise me if the followings are what are
needed in the Alpha box:
1. a synchronous card, either DNSES or PBXDI, depending on I/O bus
2. SNA Peer Server on Digital Unix
3. SNA LU6.2 programming interface on Digital Unix
Please advise.
Best regards
Chris

No - I don't believe that numbers have been published.

For what, X25? If the Peer Server is local to the mainframe, you could
use Token Ring instead of SNA.

Yes.

APPC V3.1(just released).
