The answer to questions are yes, and it depends. We need more exact
information to give you a more accurate
answer, but here are some ballparks from what we have deployed here at Sun:
Argentina to Texas is OC-1 (45 Mbps). There are two lines for redundancy
Pennsylvania to Texas is Channelized OC-1 (45 Mbps). They can vary the
speed via the WAN Layer or the MPLS QOS. The QOS has been going up in
2008 due to increased number of DTUs at their location. (not sure how
many DTU's)
Mumbai to Texas is OC-3, soon planning OC-12. There are two lines for
redundancy. This is also MPLS and is shared for multiple
purposes-customers. Sun's QOS limit has been going up in 2008 due to
increasing DTU count and transaction increases mostly due to GRC
support. (Roughly 100 DTU's currently, but planning on adding more.)
Kentucky is OC-1. They recently converted from dedicated T-1 to MPLS a
few months ago. This is channelized OC-1 (45 Mbps).
So, Sun can add WAN bandwidth as needed. (Currently 50 DTU's)
We also have another customer currently that is housing the Sun Ray
servers in Sacramento, California, and deploying the DTU's in
Singapore. (Not sure what their pipe size is, but hope to find out soon.)

2 part question:
- has anyone deployed sunrays long distance (i.e. coast to coast)
- if so, are there any band width requirements or other concerns
I'd be more concerned with latency than bandwidth. You can get GIANT
transcontinental pipes nowadays.
Peace... Sridhar
