As noted in the announcement this is something new.
We have not seen a data sheet. It might be a Tomahawk. Or it might be something else.
A NetworkWorld article says that Dell expects these to ship before the end of October
with a starting price of $22,000.
Re-introduced in October 2017, but still no data sheet. The programmability in the
feature list below suggests this might be a Cavium ASIC. The S5148 and S5048 are
speeds-and-feeds identical. The announced difference is that S5048 uses Dell's OS9
while the S5148 uses OS10.
Features specifically for the S5148
The press release projects availability in the quarter ending on November 3, 2017. Dell calls this the third quarter of 2018.
We will see.
