I’ve just been through the Lustre strategy presentation that Peter Bojanic briefed last week (previously linked here), and had a great conversation with one of my more knowledgeable friends on what look like changes in the Lustre strategy as the product moves from Sun to Oracle. I’d say the strategy is to lock up future innovation in Lustre to drive the purchase of Sun/Oracle hardware. I’d further guess that if that move does not result in increased business, Oracle will shed the Lustre effort entirely, leaving it to the community in whatever crippled state the open source portion of 2.0 is in at the time. But I’m getting ahead of myself.
For Lustre 1.8 users with existing support contracts will be “allowed” to renew them (slide 13, bullet 3), but there is no supported migration path for users on storage hardware that is not made by Sun/Oracle for customers wanting to upgrade from Lustre 1.8 to 2.0 (slide 13, bullet 2). Lustre 2.0 will only be supported and qualified (by Sun/Oracle) on Sun/Oracle hardware.
Customers who want the advanced features of Lustre 2 can purchase Oracle’s integrated storage configurations to get the highest levels of reliability, performance, and support (slide 13, bullet 4)
There also won’t be any support available from Sun/Oracle for the software-only version of Lustre 2.0 (slide 9, bullet 3), and it looks like they are planning to add features that are value add only for Sun/Oracle hardware customers (slide 5, bullet 2) that “may or may not” be open source. I’d read that as “will not.”
