On NVMe drives, I don't think you generally have any control over the HPA. Samsung Magician (windows only) has an option to increase over-provisioning. It shrinks the partition that is on the disk and erases the free space. Enterprise

Both this drive and the 980 pro have a dynamic SLC cache. When there is a significant amount of erased space available, they will each sustain about 5000MB/s. This drops to about 2000MB/s as the SLC fills. The 980 pro hits a cliff

Wow, that's 7 years earlier than the paper with Roger Faulkner that I thought was the first. I guess this is the first reference in the Faulkner and Gomes paper. https://www.usenix.org/sites/default/files&#x2F

I have the same box, but with the 32 core CPU and fewer NVMe drives. I've not poked at all the PCIe slots yet, but all that I've looked at are in NUMA node 1. This includes the on board M.2 slots. It is in NPS=4 mode.

NVMe-oF is a transport protocol between an initiator (e.g. Linux nvmf module) and a target (e.g. spdk, Linux nvmf module, etc.) much as iSCSI is a transport protocol. The storage behind the target does not need to be NVMe for NVMe-oF nor do

"For the input you can choose which type of protocol you want through the storage classes. At the output, let's say, you can do iSCSI, NVMe, and local. But the iSCSI work was there mostly for us to get us going because by defaul

If you can find your way to Costco, make an appointment with their audiologist. The test is free and hearing aids are less than $900 each. Follow-up visits are free. You do not need a Costco membership unless you decide to make a purchase.
