Hello all,
Until we have a true model of user access load, I would like to price a
"unit" of load to support the following numbers of SIMULTANEOUS users:
200 low-volume users querying against stored meta-data only over 10 million
objects in the object catalog or 1 degree^2 of the image archive, retrieving
a 1 Gbyte dataset from a single cluster/partition, and receiving it at
100Mbps. Query response time should be less than 10 seconds.
10 high-volume users querying against stored and derived meta-data with
moderately complex conditions, over 1 billion objects in the object catalog
or the full FOV of the image archive, retrieving a 6 Gbyte dataset from
multiple clusters/partitions, and receiving it at 1Gbps. Query response
time should be less than 10 minutes.
1 super-high-volume user querying against stored and derived meta-data with
highly complex conditions and 3-point correlation, over 10 billion objects
in the object catalog, retrieving a 10 Gbyte dataset from all
clusters/partitions, and receiving it at 10Gbps. Query response time
should be less than 10 days.
Please make additional assumptions you need to and document them. Then tell
me a representative set of file, database, and network servers that can
support this. Please do this as a team and have this ready for my return on
6/23. Pose questions to Tim as necessary.
Thanks!
Jeff
