Oracle Exadata, Oracle storage
This week we wrote about the Oracle Exadata storage expansion racks, which are basically just the storage cells from Exadata without any database servers. Like the Exadata itself, the storage racks come in quarter-rack, half-rack and full-rack configurations.
After publishing the story, consultant Kerry Osborne from Enkitec wrote back with his thoughts on the announcement. Here are a couple excerpts from his email to me:
The storage expansion rack is interesting. You could already buy individual storage cells ($55K), so presumably you could put these together on your own already. But it’s now packaged and there appears to be a slight discount as you buy larger configs (full rack storage is slightly less per cell than half rack). We have a customer that has run out of both storage and processing (CPU) capability on the storage cells, but the DB servers are fine. So adding additional storage is the way to go for them.
Oracle salespeople, however, might not be too excited about the storage racks:
Oracle sales people have been hesitant to recommend (just adding additional storage) because they have been trained to push the “balanced config” story saying that the ratio of DB servers to storage cells is somehow magic. So they tend to want customers to buy another quarter rack Exadata. This announcement will make it easier for customers to tell sales guys they just need more storage.
