How many hosts can you connect to a SAN ?

Does anyone have some basics to how a SAN is laid out ? I was on the HDS
site and we are looking at the USP1100 and I came across terms like
Directors,etc, but wish there was some basics on SANs someplace..
Does anyone use USP1100 for SQL Servers and any pros and cons ?
SAN vendors usually have general documentation explaining their architecture
components. That would be the best place to start.
As to the pros and cons of a particular product/model, you may get a diverse
array of opinions. For instance, we use a certain vendor and certain models.
We spent a lot of time evaluating different vendor products, and developed
our opinions. We like what we have. But then, it's not rare to bump into
folks who have chosen the vendor/product we decided against, and they seem to
be happy as well. For such an important decision, I'd ask the vendor for
customer references, even though you know you would be given only satisfied
customers.
As to the question of 'how many hosts can you connect ...', the answer is
entirely dependent on the SAN configuration.

Do you use the high end USP1100 ? If so, how many hosts can you connect to
it ? Do you ever have to take outages to all hosts to do some maintenance
work on the SAN or do you have all your hosts up and running all the time ?
