A design question with partition:
Our DB has 200GBx60 SAN storage Lun, no i/o issue. Couple big tables we like to use partition here, each table can over 1TB space.
Assume every month we have 20 days data (Business day, BD), so 20 partitions per month.
We like to keep last 3 months all BD partitions.
And data over 3 months, we only keep last week BD (5 BD) only.
I might need to use move data between partitions.
Question:
number of partitions here is much higher than 60 LUN (dbspace).
Any concern, and how to get around or best practice here.
Thanks
