Dell S5148

May 5, 2017

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.
