Looks sweet.

Just want to know when the CP121 or this will come out... My NAS is at almost 90% and don't want to invest more into M.2.

Hi jc919,

Thank you for your interest in CP121 and CP161. According to our development schedule, CP121 will be released earlier than CP161 in 2026Q1.

This looks interesting. I've been looking for a way to connect lots of M.2 NVMe SSDs without using a ton of lanes I don't have. To build on that example with the Broadcom 9600-16i, could I connect just one MCIO port to use eight SSDs in x1 mode? Or, could I connect it straight to an MCIO 8i port on the motherboard?

I'd also need M.2 to E1.S adapters but I can live with that.

You would need to use a Broadcom 9600-16i card that supports UBM function in order for the lane splitting to happen.

Also, for 2280 M.2 NVMe SSD to 9.5mm E1.S SSD Converter, we are in progress of developing it and it is planned to come out around Q3 2026. Stay tuned!

Lastly, could you kindly share your intended use case with CP161? We are all ears

I have some compact file servers that pair a Broadcom 9600-16i HBA (or similar) with two Icy Dock MB998SP-B cages (or similar), giving me sixteen SATA SSDs in a tiny package. With software RAID it's fast and affordable. Today M.2 NVMe SSDs are the same size, same price, and much faster than SATA, yet I can only connect four to my HBA (for example, with a MB873MP-B V2). With two CP161 cages I could connect sixteen M.2 SSDs and still get more speed than SATA or SAS, all in the same tiny package.

I suppose what I'd like best is a MB873MP-B V2 cage with UBM like the CP161. I've looked for years and nobody makes that!

That is an interesting application. Would you mind show some picture of it for us to admire and yes, M.2 NVMe SSD are becoming more mainstream now even in the business setting.

We were initially going to go with MB873 with UBM, however, E1.S seems to take over the market faster than we expected. As a result, CP161 would be the way to go. With CP161 and our M.2 to E1.S converter coming out, you would be able to utilize M.2 in CP161

Here's one of my 2U servers with an Icy Dock MB998SP-B and three Athena Power BP-15827SAC cages (plus two HDDs in the middle). I'm building a new box now pairing a Broadcom 9600-24i with an Icy Dock MB516SP-B. It's cheaper than two MB998SP-B cages and has that nice big fan.

I love Icy Dock but their prices doubled during Covid and never came back, so now I can get three Athena Power cages for the price of one Icy Dock. That's a tough sell!

That is a nice file server you have there. Keep up with the good work!
