PaSTA System Requirement Overview
PaSTA is a Windows .Net client application that connects and synchronizes with multiple data stores, and has 4 main physical sections: PaSTA client program, PaSTA database, PaSTA monitor and PaSTA interface. These sections can be arranged in any suitable physical configuration provided there is connectivity between them. PaSTA is a high demand, high availability application that depends greatly on how many work centers and users are involved. Customers will want to consider this in planning the PaSTA hardware setup.
PaSTA Monitor Req's
The PaSTA Monitor is a Web Service that allows SAP (or more
precisely, the BizTalk code) to communicate to PaSTA. Since it is web services, it will need to be
running IIS 6.0 or newer. It can share a
machine with other processes if necessary.
This is not a high end machine and could easily be a VM. It is recommended that this machine is NOT
one of the Citrix boxes. It can,
however, be the PaSTA database server.
This may not be desirable for security reasons.
Citrix Farm
Each Citrix box should be able to handle 30-50 users
comfortably. Higher end machines (more
CPU / RAM) will be able to handle more capacity. It is recommended that these machines be 64
bit Windows Server 2008 R2 installations with 32GB of RAM or larger. Given that larger amounts of RAM are much
cheaper than full machines, PRO recommends going with as much RAM as can be
budgeted.
Client Machines
If Citrix (or some other virtual desktop technology), then
minimum requirements will be according to the environment. If PaSTA is not using a virtual desktop but
is having the client connect directly to the database, the requirements are
listed below.
