driveAtlas: redraw the Sliger CX4712 as a real front elevation
Lint / Shell (shellcheck) (push) Successful in 10s
Lint / Shell (shellcheck) (push) Successful in 10s
The old 10-bay render was a 138-column strip of ten wide horizontal boxes,
which is not what this chassis looks like. Sliger's own photos and CAD show
the ten 3.5" bays are a SINGLE ROW of ten with the drives mounted ON EDGE,
so from the front each bay is a tall narrow slot - ten thin vertical bars in
a row is the signature of the case. Drawn as stacked horizontal trays it was
simply wrong.
Redraw it as a true front elevation at the real proportions (4U, 431.8 x
176.8 mm, ~2.75:1 with rack ears):
- two 5.25" filler blanks side by side directly above the bay row, spanning
the same width (these are unused on all three nodes)
- one row of ten vertical bay slots, solid when occupied, dim ghost when not
- the narrow front I/O strip at the right: power ring, 2x USB-A, USB-C, and
the drive-lock key cylinder
- rack ears with vertical handles bracketing both edges
There are no front fans, no reset button, no badge and no per-bay LEDs on
this chassis, so none are drawn.
All text is pushed out of the picture into BAY/DEV caption rows column-aligned
under the slots, keeping the chassis a clean silhouette. M.2 and internal
drives are not on the front face, so they are listed as a legend beneath.
Also surface the two facts that actually matter for using this map: the case
has NO backplane (each bay is an individually hand-cabled SFF-8482 to SATA
adapter) and NO per-bay LEDs, so bay numbering is a LOCAL left-to-right
convention rather than a vendor one, and a drive can only be identified
physically by its serial - there is no bay LED to blink.
Fixed 88-column canvas, identical display width on every line in monochrome
and colour, colour runs coalesced per run of like bays to keep escape churn
low, SAFE width-1 glyphs only.
