You might want to consider whether transportability is an issue. How do you get your backups to your disaster recovery site? The systems I worked on were prohibited from connecting to public networks.
You might also want to consider operational security. If your new storage device is physically on line, it is subject to things like accidental data deletion and damage from a power surge, fire, or EMP. A tape drive in a secure vault could probably survive the next mass extinction. And after you resolve all the technical issues, somebody should still bring up cost. It's not just acquisition cost per megabyte but things like equipment footprint, power, air conditioning, maintenance. And don't forget planned obsolescence. Mine was one of the last sites in the company (country?) to use 9345s. > -----Original Message----- > From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> On > Behalf Of kekronbekron > Sent: Sunday, July 05, 2020 5:13 AM > To: IBM-MAIN@LISTSERV.UA.EDU > Subject: Storage & tape question > > Hello List, > > Just wondering ... assuming there's a primary storage product out there that > can store > how-many-ever hoo-haa-bytes, and is a good product in general, it should make > sense > to begin eliminating all tape (3490/3590) use right? > First, ML1 & ML2 in HSM, then HSM itself, then rebuild jobs to write to disk, > or do > SMS/ACS updates to make it all disk reads/writes. > > Looking at the current storage solutions out there, this is possible, right? > What would be the drawbacks (assume that primary storage is super > cost-efficient, so > there's no need to archive anything). > > - KB > > ---------------------------------------------------------------------- > For IBM-MAIN subscribe / signoff / archive access instructions, > send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
