Looks like Linus will have to rebuild his servers again.  Haha

"These are not your usual Ethernet ports, however, as each supports a staggering 25Gbps - about 25x what most Gigabit"

"Samsung claims the E-SSD drive will achieve PCIe Gen4x4"

"... 24 NVMe drives will be about 7.5x faster than a single NVMe drive, whereas the same number of NVMe-oF SSDs will be about 23x faster than a single drive. "

So it's like PCIe over ethernet?

So now when your NIC fails, you can lose all your data with it.

NVMeOF is the name of this type of thing.

I'm not sure what this does except make all your data into small 1500 byte packets. Why would anyone want that?

1) just because it uses rj45 ports does not mean it uses IP and/or Ethernet. Fiberchannel for example can use the same standard cables as Ethernet despite being two different protocols. 

2) Even if it uses the IP over Ethernet doesn't mean it is limited to 1500 byte sized packages (that's just the de facto standard for internet traffic). You can run IP with mtu sizes of up to 9000 bytes if you want. Many do. It's called jumbo frames.

Also I/O operations on storage devices happen in their sector sizes which are 512 bytes or 4096 bytes, RDMA is also a requirement here.

Insane. I wonder when they'll release consumer variant of their Z SSD though.
