fork lift upgrades / replacements

Wonder how many on the list have purchased san from one vendor (emc) and
then replaced with another (hds, ibm). what type of issues did you run
into - lessons learned ...etc.

putting together some ideas for a storage meeting and was curious what this
wise list had to offer.

thx in advance.

If you are planning on phasing out the old arrays anyway...
Wait until negotiations are almost compelte, then offer to give them
your old arrays in return for an even lower price. They will usually
bite.

The big issue will be software. If the products are simple arrays, then
it is a matter of ensuring that the hardware supports the software that
you want to run on your system. This is most important for software that
relies on block-level access to the disks. Differences in controllers
can make the system behave differently.

If you are buying a system that has embedded software in it including
RAID, backup, replication, remote copy, etc. then you need to look at
how that will interact with other system components and applications.

Finally, you have the data migration issue to deal with.

Most storage vendors are trying to grab market share from each other
right now. It is reasonable to assume that you can get a lot of help
from a new vendor migrating to their systems. Get that free or at a
heavy discount.
