I decided to go for the ten-port option. System Information identifies the Cerulian N14JB as product 0x0608 from vendor 0x05e3 (Genesys Logic, Inc.)
Genesis Logic | USB Hub Product |
Hub Controller … but I don't know whether what's in the N14JB is amongst that range of controllers.
The following arrangement –

– with my two Seagate hard disk drives (Backup+ Desk, GoFlex Desk (pool named
tall)) in the ports adjacent to the power supply – seemed good enough for starters.
The apparent nesting of two other hubs interests me. Other people might have seen such things often before, but I rarely work with external hubs so this is a novelty. None of the Genesis USB 2.0 controllers linked above have more than four downstream ports so I guess that in the case, there are three controllers.
BackgroundThis Cerulian N14JB is primarily to replace ye olde Sitecom USB 2.0 Dock CN-022 that features in a troubleshooting topic,
Finder eject, reconnect, panic, type 14=page fault, zpool.
Postscript: Mac sleep during and receive involving all hard disk drives on the hubSleeps and wakes following a boot yesterday:

The first of those sleeps of the Mac occurred naturally (whilst I slept) during a relatively large stream –
- Code: Select all
sending from @ to zhandy/pockettimemachine@2013-03-28-202704
receiving full stream of zhandy/pockettimemachine@2013-03-28-202704 into tall/backups/zhandy/pockettimemachine@2013-03-28-202704
received 63.8GiB stream in 14516 seconds (4.50MiB/sec)
– a send from a single-disk pool, reception at a two-disk pool, all three on the new hub.
I'm impressed, pleased that the sleep and wake did not upset the reception.
