I've also become sufficiently annoyed at Sun for their unwillingness
or inability to ship hotplug drive carriers without (premium-priced)
drives in them to switch to Supermicro.

Below is maybe not Thumper, but you can put 2 TByte drives
at 100 EUR/TByte costs into them yourself, giving you 50
TByte raw storage (or 48 TByte raw storage, and 4x 2.5"
SSDs for hybrid storage ZIL/L2ARC cache with Opensolaris)
in 4U of rack space.

SC848A

  - 24 Hot-swap HDDs in 4U

(Quad Motherboard Support)

Optimized for enterprise-level heavy-capacity storage applications,
Supermicro's SC848 Chassis supports 4-way serverboards that demand high
volume I/O or computational usage and features 24 hot-swap 3.5" SAS/SATA hard
drive trays and 2 fixed internal hard drive bays in a 4U space. The SC848
design offers maximum HDD per space ratio in a 4U form factor, high power
efficiency (up to 88%) with (2+1) redundant 1800W power supply, optimized HDD
signal trace routing and improved HDD tray design to dampen HDD vibrations
and maximize performance.
