StarTech SV831DUSBUK Review

The StarTech SV831DUSBUK is an 8-port 1U rackmount USB VGA KVM switch kit that includes all 8 cables and mounting hardware, cascadable to 64 computers.

The kit format is the selling point, 8 complete USB/VGA cables and rack mounting hardware ship in the box, so there's no separate cable order needed to get a full 8-server rack running. Cascading support extends it to 64 computers if one rack unit outgrows itself. Versus StarTech's own SV1631DUSBU, doubles the ports for roughly the same per-port cost if you need to cover more servers. Versus the Tripp Lite B032-008-19, a similar 8-port rack KVM at a comparable price, worth comparing on rack depth if space is tight.

Complete Kit for Rack Deployment

All 8 of the required USB/VGA cables ship in the box along with rack mounting brackets, which removes the usual headache of ordering the right cable lengths separately when outfitting a server rack.

Cascadable to 64 Computers

Daisy-chaining multiple SV831DUSBUK units extends control up to 64 total computers, giving a growth path without replacing the base switch.

Comparison to Alternatives

Versus StarTech's own SV1631DUSBU, doubles the ports for roughly the same per-port cost if you need to cover more servers. Versus the Tripp Lite B032-008-19, a similar 8-port rack KVM at a comparable price, worth comparing on rack depth if space is tight.
