Hi all,
I fully understand that within a cost effective point of view,
developing the fishworks for a reduced set of hardware makes , alot,
of sense.
However, i think that Sun/Oracle would increase their user base if
they make availabe a Fishwork framework certified only for a reduced
set of hardware, ie :
• it needs Western Digital HDD firmware version x.y.z
• it needs a SAS/SATA controller from a specific brand, model and
firmare ( LSI SAS1068E )
• if SSD's are used they need to be from vendor X with firmware Y
• the system motherboard chipset needs to be from vendor X or Y and
not from Z
Do not underestimate the cost and complexity of maintaining
compatibility
matrices (I call them "sparse matrices" for a reason :-)
Within this possible landscape i'm pretty sure that alot more
customers would pay for the Fishworks stack and support, given the
fact that not all customers "need" aKa can afford, the Unified
Storage platform from Sun.
There are competitors delivered as software-only: NexentaStor seems to
be
well designed and EON is progressing nicely.

Anyway..Fishworks it's an awesome product! Congratulations for the
extreme good job.

With that said I'm concerned that there appears to be a fork
between the opensource version of ZFS and ZFS that is part of the
Sun/Oracle FishWorks 7nnn series appliances. I understand
(implicitly) that Sun (/Oracle) as a commercial concern, is free
to choose their own priorities in terms of how they use their own
IP (Intellectual Property) - in this case, the source for the ZFS
filesystem.
Hey Al,
I'm unaware of specific plans for management either at Sun or at
Oracle, but from an engineering perspective suffice it to say that
it is simpler and therefore more cost effective to develop for a
single, unified code base, to amortize the cost of testing those
modifications, and to leverage the enthusiastic ZFS community to
assist with the development and testing of ZFS.
Again, this isn't official policy, just the simple facts on the
ground from engineering.
I'm not sure what would lead you to believe that there is fork
between the open source / OpenSolaris ZFS and what we have in
Fishworks. Indeed, we've made efforts to make sure there is a
single ZFS for the reason stated above. Any differences that exist
are quickly migrated to ON as you can see from the consistent work
of Eric Schrock.
