The Violin plays only for a single one-ear box, or for small groups with two ears as well?

Just curious: How many PCIe ports a violin box has?  Can I have redundant connections (two
PCIe HBAs per host)?  Can I plug various hosts to the violin, much like I could with a storage
with multiple FC ports?

This sort of information really should be in their webpages, but I have failed to locate it
anywhere.

The Violin 1010 box has two PCI-e 8x (external) links, each delivering about 1.7 Gbytes/sec of
read throughput that can be connected in parallel to the same host for over 3 GB/sec of read
bandwidth, or connected to two different hosts for redudancy.

They really out to post this info in a blinking, scrolling banner on their site, if ask me.

Agreed.  Nobody sane would bother to buy a US$50k+ storage unit without knowing this
information first, it is weird to not publish it up front.

Two ports is way too little for this class of hardware, IMO.  They need to add two more.

One needs two ports per host for HBI and cabling redundancy, and usually one will also need to
be able to connect a minimum of two separate hosts to the same storage (for HA redundancy).
Typically, a high-uptime HA setup would have two hosts connected via two PCIe links each to two
Violin boxes.
