Black Box Explains...Multi-user ServSwitch products vs. multipoint access ServSwitch products.
A multi-user ServSwitch, such as the Matrix ServSwitch, enables two or more users to access different servers at the same time. So, for instance, one user can access “Server A” while another user accesses “Server B.” This is considered a “true two-channel” architecture because two users have independent access to CPUs. It should be pointed out that multiple users cannot access the same server at the same time.
A multipoint access ServSwitch, such as the ServSwitch Duo, provides two access points for control stations but requires that both users view the same server at the same time. So, if one user is accessing “Server A” on his screen, the other user is also seeing “Server A” on his screen. If the second user switches to “Server B,“ the first user will also switch to “Server B.” Only one of these users is actually in control. The user in control stays in control until his workstation is inactive for a period of time (selectable). Then the other station can take control.
A multipoint access ServSwitch is useful when simultaneous, independent access is not required—just the ability to access CPUs from more than one place.
