Carlos,
I know the generations of TS11xx, because I use to teach tapes and
because I'm interested in. Last, but not least I've been using it form
20+ years.
However the last member of the Jaguar family which could be attached
directly (*) to the host was TS1140.
Next generations and subgeneration (TS1155) could not be attached
directly. Only as a backend of VTS or other VTL.
(*)
My and not only mine definition of native tape or tape directly attached:
When you mount a tape in MVS the physical cart is being mounted. The
cart is the logical volume, 1:1.
Physical drive is 1:1 logical 3950 (or 3490) device.
Contrarily, VTS and other virtual tape solutions offer multiple emulated
drives and volumes - but this is some POWER server with disk array for
storing files (logical volumes).
IMHO irrelevant for the above considerations: Physical connectivity to
IBM drives required a controller box between the drive and CPC, it was
true for Jaguar models J1A-1140, for whole Magstar family and for 3490
family, and earlier 3480. Notable difference for STK Titan (T10000)
drives was lack of controller.

There are eight generations of 3592 tape drives: TS1170 (Models 70F & 70S), TS1160
(Model 60G), TS1155 (Model 55G), TS1150 (Model E08), TS1140 (Model E07), TS1130 (Models
E06 & EU6), TS1120 (Model E05), and J1A. All generations of 3592 tape drives
TS1170 can hold 50TB in one cartridge in native format and near to 125TB
compressed!!!

Assunto: Re: Mainframe physical tape backup Still ?

Hello
Apart from IBM, Are there any vendors who still have physical tape backup
solution.
I know Oracle withdrew it's physical tape solution last year.
Hitachi doesn't have physical tape backup solution for mainframe.
Does anyone know if fujitsu still has physical tape backup solutions?
I know its best to opt for tapeless solution but our organization for
different reason we are looking for mainframe physical tape backup solution
Any information on this would be much appreciated.
No. No vendor has physical tape attached to mainframe.
And very few still have tape as a backend to the VTS solution.
The last supported drive was TS1140.
STK/Sun/Oracle drives were withdrawn also and AFAIK before EOS of TS1140.
