Nice subject?
Anyway does anybody else out there have 3592 drives? Are you using them
for DFSMShsm ML2 data? At present, we are debating putting HSM ML2 data
on 3592 carts. The other option is to use 3490E __virtual__ carts and
use OpenTECH's TapeCopy to stack the virtual carts onto physical 3592
carts. The main "worry" about this, in both cases, is that we won't get
out money's worth due to having too little data on the individual 3592
carts. The number I heard is $200/cart, so we don't want to "waste"
them.
Any help?
John,
One of my customers has 3592 inside an ATL and we use them for all HSM
activity. Used to use TMM but have converted that to CA-VTAPE. Downsides
are it can take a long time for HSM or CA-VTAPE to recall from the
back end of a 300Gb+ cart. Currently investigating dual copy
functionality for both products, which will cover DR and data loss if a
cart is lost.
Another customer uses 3590 inside an ATL on 30Gb carts and the
recall/recycle/tapecopy performance is OK. If we lose a cart the impact
will be nowhere near as high as if we lose a 3592 cart.
I prefer VTS to TMM or CA-VTAPE but that's another dollar or two.
