Oracle RAC scalability(does it linearly scalable upto 20-30 nodes)
588495Jul 20 2007 — edited Jul 25 2007We are looking datastorage solution as Oracle -RAC for following performance requirement
Application is generating Resources which we want to store in database and provide searching on this resources.
Resource have 2 part one is data and another one is meta
Data contains textual/binray data like txt/html/doc/excel/pdf/image file etc
meta contains 30-40 different property telling something about data.
Average resource size is 10K
Insertion speed required for such resource (Data + Meta ) 2Gbps(30K Resource/Second )
We want indexing also on data and meta.
We used single oracle database and created resource table which has 40 column for meta property and one column of blob type for data.
Performance achieved is 100Mbps insertion speed (on normal machine)
Now to go to 2Gbps we are thinking to use Oracle RAC to scale it up to 2Gbps Insertion speed.May be 20 Node is required to scale it upto 2Gbps.
Now my question is does Oracle RAC provide close to liener scalability upto 20-30 nodes or not.
Key requirement is to achieve insertion speed upto 2Gbps
High availability of oracle rac can be added advantage for us but key concern here is scalability not fault tolerance.
