I've been reading, with great (personal/professional) interest about
Sun getting very serious about SSD-equipping servers as a standard
feature in the 2nd half of this year. Yeah! Excellent news - and
it's nice to see Sun lead, rather than trail the market! Those of us,
who are ZFS zealots, know the value of a ZFS log, and/or ZFS cache
device and how these devices can (very positively) impact the
performance of a ZFS raid configuration built on cost effective SATA
disk drives. But - based on personal observation - there is a lot of
hype surrounding SSD reliability. Obviously the *promise* of this
technology is higher performance and *reliability* with lower power
requirements due to no (mechanical) moving parts. But... if you look
broadly at the current SSD product offerings, you see: a) lower than
expected performance - particularly in regard to write IOPS (I/O Ops
per Second) and b) warranty periods that are typically 1 year - with
the (currently rare) exception of products that are offered with a 5
year warranty.
Obviously, for SSD products to live up to the current marketing hype,
they need to deliver superior performance and *reliability*.
Everyone I know *wants* one or more SSD devices - but they also have
the expectation that those devices will come with a warranty at least
equivalent to current hard disk drives (3 or 5 years).
So ... I'm interested in learning from anyone on this list, and, in
particular, from Team ZFS, what the reality is regarding SSD
reliability. Obviously Sun employees are not going to compromise
their employment and divulge upcoming product specific data - but
there must be *some* data (white papers etc) in the public domain that
would provide some relevant technical data??
