hi ya michael
- you're right in most things you're saying for
cots vs reinventing the wheel
but since i gave you the impression we prefer
to "reinvent the wheel" and/or avoid dell/hp/ibm/metoo,
here's some whacky background info for more
poking and shaking of the fingers :-)
- in the days before *.com, there were very few ( 2 )
vendors of reasonable 1U chassis, so we made our own
custom chassis per customer requests to solve
the heat problem of p3-500 and AMD athlons and
provide more than 1 disk
- there were 2 very very bad 1u chassis
from the industry standard rackmount vendors
- there was NO 1U power supplies so we
designed our own ... and of course, by
the time we finished the prelim designs,
we could buy $150 prototype 1U power supplies
which we did and placed orders for more
which dropped in price overnight
- now of course, everybody has rackmounts chassis
and if you look closely, its mostly the same chassis
re-branded as antoher "me too" vendor
- there are those that make their own chassis
( dell, tyan, mb-vendors, ibm, hp, etc )
- for tommorrow's market:
- we're reinventing the wheel again, for blade
boxes that will support 10 independent systems
with 15TB in 4U of space or about 160TB per cabinet
- i'm again, assuming we'd have to design our
own custom 24port gigE switch since the budgets
doesn't allow $$$ for fancy cots 24-port gigE switches
but, that is the minor hangup for now ...
where we do twiddle dee.. twiddle dah to see
who comes up with a cheap 24-port gigE that has
the sustained performance between any 2 nodes
- i think plugging 16 disks into one motherboard
will be serious bottleneck for managing 15TB of disks
- can you/we buy a 100TB system off the shelf ???
- yes .. but its not cheap ...
and we're way underpriced so we're hoping to
get the hw contract
add back in for the marketing/sales and tradeshow costs
and we'd be in the same price point as
everybody else ... ( 100x mark up of hw costs )
- it's targeted for a major colo facility
- than add "services" to the custom hardware and hopefully
everybody are happy campers
