Windows Longhorn Clustering (Beta 1)
- Rodney R. Fournier
Update:
The current
Longhorn beta does not contain anything for clustering, it is simply
not in the product at this point. I confirmed this with High
Availability group at Microsoft. Look for clustering in the next
version.
Bummer to,
cause I have a Longhorn DC and two Longhorn member servers waiting
to go...
More after I
get the next release.
R2 to add
several SAN enhancements
- Rodney R. Fournier
While this is
not 100% clustering, a lot of you use a SAN for your clusters.
See
http://www.techworld.com/storage/news/index.cfm?NewsID=4374 for
an article titled Windows Server 2003 adds storage management. It
has some pretty good detail on R2.

Word of
the Day - Quorum
- Rodney R. Fournier
I subscribe to
the dictionary.com word of the day RSS feed. Today the word is
Quroum.

“Quorum comes
from the Latin quorum, "of whom," from qui, "who." The
term arose from the wording of the commission once issued to
justices of the peace in England, by which commission it was
directed that no business of certain kinds should be done without
the presence of one or more specially designated justices.”
Very interesting stuff.
How much of a geek am I? I read the word of the day and thought,
cool I know this one (thinking of clustering only). Then I read both
definitions on the page and thought, hey, you forgot one.
You don't
need to run a cluster in England to understand the importance of the
quorum to Micorsoft clustering. Microsoft's definition of the
quorum:
“The quorum resource is a
storage-class resource and it is used to store the definitive
version of the cluster configuration. To ensure that the cluster
always has an up-to-date copy of the latest configuration
information, the quorum resource must itself be highly available.”
So, you could go as far
as saying that quorum = clustering. What a great word of the day! I
wonder when resource will be the word of the day?
