RE: IBM i Now Supports USB Flash Drives -- MIDRANGE-L

Yeah I agree that Larry's point on speed and throughput is well taken.

I did mention Windoze...I guess you're right, some missed it :)

The point of the original post was not for keeping a save file for
occasional backups or transferring files, yes we have been doing that
for some time. The poster was considering using a USB attached device
for a primary back up medium. Larry's point was USB attached storage of
that type will be too slow and unreliable as compared to tape.

If your discussing Winders, then make sure you point that out, since not
everyone on the list will understand it.

Jim,

I was talking in a WINDOWS environment..and I do system transfers and
recoveries in that environment ALL THE TIME.... Usually a minimum of 500
gig a pop...1+tb's is a norm....NO PROBLEMS...NO DATA LOSS....

As for using it in an "I" environment....uh, how many of us have been

doing

binary FTP's of save files for how long now???? And, yes, it works JUST
FINE!:)

And when was the last time you did a real recovery from that device? Not
just an object or two but a real recovery on IBM i?

With all due respect to Dr. Franken, I've been using WD USB attached
external drives for offline server storage/backup/recovery for about 10
years now without any problems that I wouldn't encounter in a tape
environment...:)

Good theory I suppose but USB 2.0 is nowhere near the speed of LTO
(35MB/s theoretical vs 120MB for LTO4 and 140MB for LTO5)

Plus I wouldn't personally trust that 'el-cheapo' WD drive as much as I
would an LTO tape when being transported on and off-site. RDX is much
better suited for that.

If you have USB availability, why can't you then attached external

drives

for offline backup, etc? I can get a 4tb WD external for a few

hundred

bucks...should be LOTS faster than tape and not to mention

CHEAPER!:)

Holy cow! Brain is spinning....

Today, IBM is adding support to use USB Flash Drives as a

second type

of

RMS technology. Flash drives can hold as much data as multiple

DVDs

and

can typically access the data much faster. This allows a much

convenient way to move data (either IFS or save data) to

another

machine. IBM does not qualify nor recommended any particular

device,

but

typical USB 2.0 devices from 2 to 32GB have been used in our

testing.
