IBM announced today support for the server Time Protocol (STP) in the
zSeries hardware.
Availability of Server Time Protocol can:
* Help improve time synchronization for z9 EC, z9 BC, z990, and z890
* Support a multisite sysplex distance up to 100 km
* Synchronize servers and Coupling Facilities across three sites
(data centers)
* Coexist with an External Time Reference (ETR) network
* Allow concurrent migration from an ETR network when properly
configured
Unfortunately, z/VM, and guest running under z/VM (e.g., Linux, z/OS),
Linux in an LPAR and z/VSE can not take advantage of this new feature.
