This is a quick message to my forwarding partners that on Sunday,
October 27, 2013, the SJVBBS (W6RAY) BBS will be offline for a short
time. The BBS will be moved to a Raspberry Pi with two TNC-Pis connected
to it. This setup will be located entirely at the repeater site (Park
Ridge) instead of via remote. The gateway IP address will remain the
same as will the AMPR IP addresses.
The setup is currently in testing using a different alias and SSIDs at
ground level. If the test is successful, then it will be installed at
the repeater site.

Do you have external storage? The SD cards tend to corrupt over time,
especially if they have a lot of delete and write cycles.

Or else get the type specifically meant for that purpose
(industrial/commercial grade). They have much higher write cycles and
leveling algorithms to distribute the write cycles more evenly across the
device.

Which brands/types of flash don't have leveling algorithms in them? It was my
understanding this is a necessity.
Which brands/types are commercial/industrial grade?

It's not a brand issue, per say, although some brands are more targeted
toward consumers. Search MLC vs. SLC and you'll learn about the differences
in the underlying structure and why SLC is more expensive but also more
reliable and lasts 10 to 20 times longer. And yes, I suppose all SSDs have
a leveling algorithm but the hardware engineers at my last company got
non-disclosure access to the algorithms from different suppliers and
commented that there's definitely a significant difference.
Another thing you can do to extend the life is to get a bigger drive than
you normally would. The rule of thumb is that if you double the size of the
storage, you double the lifetime. (Actually, it's intuitively obvious that
if there is double the amount of space, then each part of the space should
be used half as much.)
These guys produce custom PCs for commercial, automotive, industrial
systems. You can see a few types/vendors there.

While this may be slightly off topic, since many are using Pis now,
what's the recommended drive for these units? (make/model please).
Thanks in advance.

Due to several suggestions as well as other research, I have decided to
postpone installing the aforementioned Pi setup at the repeater site. I
will add external drive space with a powered USB HUB as well as put
everything inside an appropriate enclosure before installation.
Thanks for all the input.

The latest MCM Electronics catalog offers a rackmount Pi enclosure
that has room for a hard drive, power cube, etc. I'm planning on
ordering one.

Brian, is there room for more than one pi in that enclosure? I'd like to
find a rackmount enclosure that will take 4 or more pi's...

It's hard to tell from the small picture in the catalog
but it looks like it'll hold at least two Pis.

What a waste of a rack shelf. I suppose you could use the extra space
for other devices besides two Pi's but for someone looking to do more
with that space they really screwed it up with that uPi cut out on the
front face.
Anyone with a little sheet metal experience could produce that shelf
for $5 worth of sheet aluminum and a bending brake.
