IBM eServer - Using the Geographic LVM in AIX 5L
Absolutely critical technology if you are at all interested in DR (Disaster Recovery). I know at least two customers who have used this with synchronous updates (i.e. the local disk update is synchronized with the remote disk update) and seeing little overhead even over a distance of about 150 miles between data centers. This is an ideal technology for people looking to setup DR for their WebSphere Application Server, Portal, Process Server, MQ, DB2 and the list goes on and on. I'm absolutely excited about this technology and the potential impact this can have for our high availability site customers.
If you haven't read up on GLVM I highly recommend taking the time.
"GLVM can help protect your business from a disaster by mirroring your mission-critical data to a remote disaster recovery site. If a disaster, such as a fire or flood, were to destroy the data at your production site, you would already have an up-to-date copy of the data at your disaster recovery site."
