Dear list,
I am not so sure whether that claim is true. In fact quite to
the contrary. Almost all of Yahoo runs on Net Apps., with
literally 1000s of e-mail users and other web-users it portrays
an OLTP environment. There are many other sites that use Net
Apps.
If any there some issues with D/W environments in the past 2
years. With the introduction of the F840 and F840c, that is now
a moot point, as it is 100% fiber-enabled, and both OLTP and D/W
are supported without any issues. The issue with performance
comes about only when the required network infrastructure is not
put in place. Otherwise, it is as reliable as a regular
filesystem (NFS 2.0 and 3.0) are significantly more reliable
since they use TCP for their communications instead of UDP.
Net Apps. have also come a long way in supporting enterprise
class storage (upto 12 Tb) on a F840c and the performance on
these appliances have come a long way. They are definitely a key
player in the future storage market and their Oracle market
share is growing.
Cheers,
Gaja
