Looking at the web site for Sun''s SSD storage products, it looks like
what''s been offered is the so-called "Logzilla":
http://www.sun.com/storage/flash/specs.jsp
This is the unit that is used with the "zpool add log devX" command.
Are there any plans to add "Readzilla" offerings to the product line
("zpool add cache devY")?
Regardless of the answer, in the meantime, are there any products that
are (unofficially?) recommended at this time (that can be purchased
from third parties)? What devices are being used in the Amber Road
products?
Also, on the currently available SSD, there''s a ''Try and
Buy'' logo:
would it be possible to ''borrow'' one of these SSDs for the
sixty days
and run benchmarks, and if it doesn''t help, remove them from the ZFS
pool where they were tested? I was under the impression that it''s
currently not possible to remove Read- and Logzilla devices.

The 100 GByte SSD is read optimized, ala STEC MACH8.> > Regardless of the answer, in the meantime, are there any products that > are (unofficially?) recommended at this time (that can be purchased > from third parties)?

Sun is currently in its fiscal Q4, which is otherwise known as "the quarter for non-linear thinking." They can be replaced. -- richard

I''m more curious about: we added this device, but it doesn''t improve things, so let''s remove it completely from the configuration. Just as you can''t remove a vdev to a pool once it''s been added (and shrink the pool), can you remove a -zilla device once it''s been latched onto a pool''s configuration?

Is this actually the STEC device, or just a rebranded Intel SSD? Not that there''s anything wrong with the Intel or anything, but if you were going to buy it it''d probably be dramatically cheaper buying it from someone other than Sun, if Sun''s service contract, etc, wasn''t important to you.

Hi All, Currently, the ssd''s used in 7000 series are stec''s, ssd''s used inside servers are intel Sent from a mobile device Mertol Ozyoney On 20.Nis.2009, at 06:09, Scott Laird <scott at sigkill.org> wrote:> On Sun, Apr 19, 2009 at 10:20 AM, David Magda <dmagda at ee.ryerson.ca> > wrote: >> Looking at the web site for Sun''s SSD storage products, it looks >> like what''s >> been offered is the so-called "Logzilla": >> >> http://www.sun.com/storage/flash/specs.jsp > > You know, those specs look almost *identical* to the Intel X25-E.
