ServerNet Cluster Web

What’s the difference between ServerNet I and ServerNet II? ServerNet I is
the first-generation ServerNet protocol. It features 50 MB/s speed, six-port routers,
parallel encoding, and a 64-byte maximum packet size. ServerNet II is the
second-generation ServerNet protocol. It features 125 (or 50) MB/s speed, 12-port
routers, serial encoding, and a 512-byte maximum packet size.

Servers
Can a ServerNet cluster include different types of NonStop™ S-series
servers? Yes. All NonStop™ S-series models can participate in the same cluster.
However, some models of NonStop™ S-series servers can support greater distances
between nodes.
Can a ServerNet cluster include NonStop™ K-series servers? No. NonStop™
K-series servers do not use the ServerNet protocol. Only NonStop™ S-series servers
can join a ServerNet cluster. Note that a NonStop™ S-series server can
simultaneously be a member of a ServerNet cluster and a FOX ring. (FOX rings can
contain multiple NonStop™ S-series and NonStop™ K-series nodes.) In this
arrangement, all of the servers can communicate with each other using Expand.
Can a server be a member of two different ServerNet clusters at the same
time? No. While a NonStop™ S-series server can be a node in a FOX ring and a
ServerNet cluster at the same time, a server cannot simultaneously be a member of
two different ServerNet clusters.

ServerNet Switches
Can any ServerNet Switch product be used in a NonStop™ Cluster Switch
(Model 6770)? No. Only the 12-port ServerNet II Switch can be used in a 6770
switch. Neither the ServerNet Switch used for Windows NT clusters, nor the
NonStop™ ServerNet Switch (Model 6780) are supported for the star topologies.
There are circuit board and firmware differences between the cluster switch models
used in these clustering applications.
How are the cluster switches packaged? Nonstop™ Cluster Switches (model
6770) can be packaged in a cluster switch enclosure or in a 19-inch rack. The
cluster switch enclosure resembles—but is half the height of—an S-series system
enclosure.

Can I stack Nonstop™ Cluster Switches (Model 6770) on top of each other?
Although there is no technical limitation, stacking Nonstop™ Cluster Switches on top
of each other is not recommended. To reduce the likelihood of cabling errors, HP
recommends that the X- fabric and Y-fabric Nonstop™ Cluster Switches be installed
with some distance between them. Do not install Nonstop™ Cluster Switches next to
