What does SAN means in the context of Solace MQ?

Question

While exploring the Solace's MQ product, I came across the term SAN:

"When receiving applications are disconnected or can’t keep up with the flow of messages, their backlog is pushed to a SAN".

From: http://solacesystems.com/products/mq-messaging

I assume it's somehow relates to memory storage, but I would be happy to get a full explanation about it.

Answer 1

It isn't "Storage Area Network"? ( http://en.wikipedia.org/wiki/Storage_area_network )

Answer 2

In this context SAN does indeed mean Storage Area Network. The Solace Message Routers can store messages marked as persistent on storage that is attached to the Solace appliances via a fibre channel Storage Area Network.
