Veritas vol-mgr 4.0: what are its block sizes

On an E25K with Solaris-8 and Veritas Volume Manager 4.0, the "vxstat"
output give me figures like
OPERATIONS BLOCKS AVG TIME(ms)
TYP NAME READ WRITE READ WRITE READ WRITE
vol omspdbs 0 527 0 6167 0.0 3.5
vol omspdbs 0 477 0 4992 0.0 3.5
vol omspdbs 0 403 0 4303 0.0 3.3
vol omspdbs 0 506 0 5411 0.0 3.2
vol omspdbs 0 523 0 5878 0.0 3.7
I want to find the throughput from these figures.
For example for the writes:
(number of blocks written) * blocksize / (average time spent in writing)
-> the missing bit here is that "blocksize" : how much is it ?
Is it the filesystem block size (8KB), or what ?
thx a lot for your hints !
Rob
