“... what a
departure for the biggest Xen shop in the world.”

"vCenter for KVM" available today’
Fujitsu
IBM
“The ultimate
air-gapped backup storage just got better – IBM has announced LTO-8 with double
capacity of the previous LTO generation (12TB native capacity per cartridge), and
performance of up to 360MB/s.”
“IBM research
recently demonstrated the ability to record data at an areal density of 201
gigabits per square inch on magnetic tape. That translates to the equivalent of
330TB of data stored in a tape cartridge about the same size as the palm of
your hand.”

Non-Disruptive SVM-DR Vserver Cutovers in
ONTAP 9.3:
This is tech
preview only (no release date yet). You can see the commands as below. It does
need to be enabled (don’t ask me, I’ve yet to discover this):
::>
set advanced
::*>
vserver migrate ?
cleanup
*Remove migrating entity
cutover
*Perform Cutover of the migrate operation
pause
*Pause a Vserver migrate operation
repeer
*Repeer Existing Vserver Peer Relationships after Vserver Migration
resume
*Resume a migrate operation
show
*Display status of migrating Vservers
show-progress
*Display status of volumes in a migrating Vservers
show-volume
*Display status of volumes in a migrating Vservers
start
*Start the Vserver migrate operation
Measuring performance between nodes:
ttcp and xttcp are
removed from ONTAP 9.3 and were replaced by iperf3 (works in the systemshell). Clustershell
alternative that should work with any SVM from ONTAP 9.3 is below.
::>
set advanced
::*>
network test-link ?
run-test
*Test link bandwidth
show *Display test results
start-server *Start
server for bandwidth test
stop-server
*Stop server for bandwidth test
::*>
network ?
test-path *Test path performance between two nodes
