Solid state disk?

Todd,

I'll do my best to give you a summary of our results to date. We will be
publishing a white paper that goes into nauseating detail later this week
for those who might wish to delve into the depths of the methodology and the
results. Essentially the experiment was to see if we could find a way to:

1. Optimize an existing network to significantly improve the performance of
Vantage
2. Perturb the network infrastructure as little as possible
3. Cost less than other alternatives

What we were trying to immediately eliminate was the brute force solutions
(replace all the workstations, network and servers) and the exotica like
fiber to the desktop and the like. We began by assuming a uniform
configuration for both server and workstation. In this case 1.6mhz Zeon
512Meg 133mhz 40Gb 10/100nic...etc. The assumption being that the fastest
performance possible for Vantage is standalone since it removes the network
from the equation completely. So we took the base timings for a variety of
activities in Vantage running stand alone with a single user and assumed
that those were the baseline from which to measure. I realize I'm glossing
over quite a bit but bear with me...

The initial results indicated that workstation performance varied from 30%
to 150% slower than standalone in the reference configuration for a single
user and degraded significantly (2x to 3x) as the user count increased
beyond 20 - 25. Again, we will make all of the numbers available as soon as
I can complete compiling them.

Next we added the SSD to the server and once again went about the same
tests. This time the single user came in at 10% to 70% of the initial
reference config but the interesting thing was that the degradation
decreased as we added users. Finally, we added the Gigabit backbone and
local caching. Here, the results were the most dramatic with workstation
times running 8% to 25% off of the reference platform but the really amazing
result was that there was almost no discernable performance degradation as
we added users. We even ran an internal test with NetIQ Chariot where we
loaded up 100+ users and saw very little performance loss from standalone.

The cost for this exercise came it at approximately $150 per seat with the
ability to decrease depending upon the use of local caching (it makes a
difference).

Hope this helps.

Michael,

If you do more research on these SSD cards relative to Vantage would you
please post the results on the list?

Yup, try to keep it this side of a sales pitch ... :-)

Same goes for anyone else on the list. If you setup a SSD for
Vantage/Progress I think we would all be VERY interested in the performance
gains and the costs involved.

Thanks,

Todd Anderson

I know the group's policy so I will try to keep this as fact based as
possible...

Yes, we have tested it internally and in several production environments.

Yes, there are a host of other performance considerations that need to be
addressed in order to fully achieve the benefits of the SSD. They can all
be addressed at very low cost.

Resellers can get you more competitive pricing...

Competitors are MUCH more expensive and use a SCSI bus for considerably
lower throughput.

I'll be happy to take the remainder offline should anyone have some
additional questions.

Thanks Todd

No idea on price or who the competitors are.

But I could see putting a DB on one with real time backup to disk every 4
hrs. The only concern I would have would be if a 100 mips Ethernet card
would then become the primary bottleneck for throughput.

No idea on price or who the competitors are.

But I could see putting a DB on one with real time backup to disk every 4
hrs. The only concern I would have would be if a 100 mips Ethernet card
would then become the primary bottleneck for throughput.

Has anyone tried one of these new style "Solid state disk"s in a
production
environment?

I'm guessing that Vantage would just fly with the DB located on one of
these
critters.

I know the group's policy so I will try to keep this as fact based as
possible...

Yes, we have tested it internally and in several production environments.

Yes, there are a host of other performance considerations that need to be
addressed in order to fully achieve the benefits of the SSD. They can all
be addressed at very low cost.

Resellers can get you more competitive pricing...

Competitors are MUCH more expensive and use a SCSI bus for considerably
lower throughput.

I'll be happy to take the remainder offline should anyone have some
additional questions.

Thanks Todd

That price is for an unpopulated board and while they do sell it in that
configuration I would highly recommend that you opt for the populated
version as that is the only warrantied system. Since the integrity of the
system is completely dependent upon the compatibility and quality of the
chips, skimping here would be "penny wise and pound foolish" for your
system.

As for the nic...let's just say that that wonderful .06ms access time
doesn't end up doing a whole lot of good if the data just ends up queued up
at the nic...

A Gigabit backbone connection might just do a bit to mitigate the network
bottleneck.

But right now with our Raid 10 SCSI array, the network is the primary
bottleneck. We'll be upgrading to gigabit soon, so the storage will likely
become a bottleneck.

Agreed...RAID arrays can nearly duplicate the SSD's throughput. Where RAID
cannot compare is access time. The SSD is up to 10,000 times faster
accessing the data and it is this performance number that directly
translates to improving the user experience when the data being transferred
is in relatively small packets (ie. <100Mb). What becomes critical under
these conditions is network latency not throughput.

A Gigabit backbone connection might just do a bit to mitigate the network
bottleneck.

But right now with our Raid 10 SCSI array, the network is the primary
bottleneck. We'll be upgrading to gigabit soon, so the storage will likely
become a bottleneck.

That price is for an unpopulated board and while they do sell it in that
configuration I would highly recommend that you opt for the populated
version as that is the only warrantied system. Since the integrity of the
system is completely dependent upon the compatibility and quality of the
chips, skimping here would be "penny wise and pound foolish" for your
system.

As for the nic...let's just say that that wonderful .06ms access time
doesn't end up doing a whole lot of good if the data just ends up queued up
at the nic...

Base unit is circa 400usd. Why would you need an nic?.

No idea on price or who the competitors are.

But I could see putting a DB on one with real time backup to disk every 4
hrs. The only concern I would have would be if a 100 mips Ethernet card
would then become the primary bottleneck for throughput.

Has anyone tried one of these new style "Solid state disk"s in a
production
environment?

I'm guessing that Vantage would just fly with the DB located on one of
these
critters.
