Determine the following parameters:
Maximum number of concurrent users, nusers.
Average BLOB size, s.
Maximum transaction rate per user, referred to as NTPS.
Determine the size in Gigabytes of the maximum primary data volume, V data.
Use the following formula:
Vdata = nusers . s
Determine the maximum HADB data transfer rate, R dt.
This reflects the data volume shipped into HADB from the application side. Use the following formula:
Rdt = nusers . s . NTPS
Determine the number of nodes, N NODES,.
Use the following formula:
NNODES = Vdata /5GB
Round this value up to an even number, since nodes work in pairs.
