NVMe is an acronym for Non-Volatile Memory Express. It’s the protocol that allows PCI-e data to be read or written. It’s a host controller interface designed to meet the needs of PCI express-based solid-state storage devices. Member firms produced the NVMe version 1.0 specification in 2011. Other versions have since been released.
NVMe was created for NVM technologies to allow efficient access to storage devices constructed with NAND flash technology and future high-performance persistent memory technologies. NVMe employs a new storage architecture that spans the software stack to hardware devices and systems, eradicating the hard drive legacy of SATA and SAS.
It is designed for SSDs with Flash technology.
- It supports 64K command queues.
- It can send 64K commands per queue, utilizing low CPU cycles.
- It has a latency of about 2.8 microseconds.
- It communicates directly with the system CPU.
- IOPs (Input/Output Operations per Second) over 1 million are possible with NVMe.
Benefits or Advantages
The following are some of the advantages or benefits of NVMe technology:
- It provides better storage since PCIe sockets transfer 25 times more data than SATA connectors.
- It has a faster response time than AHCI (Advanced Host Controller Interface) SATA drives because NVMe sends commands twice as fast. In addition, IOPS surpassed 1 million, which is up to 900 times quicker than the AHCI counterpart.
- It has a higher level of compatibility because it communicates directly with the system CPU.
- NVMe-based SSDs function with all major OSs (Operating Systems) regardless of form factor.
- NVMe has an end-to-end latency of fewer than 10 microseconds, including the software layer.
- NVMe supports the tunneling protocol, which helps to protect data privacy.
- NVM express offers significantly more bandwidth than SATA or SAS.
NVMe Matters in Data Center
NVMe Matters in Data Center
Organizations are investing in the ongoing digital transformation occurring in the data-heavy enterprise environment, and storage techniques are improving as a result. SATA (which supports both SSDs and spinning hard disc drives) has been the dominating protocol until now, but with the growth of non-volatile memory express, the gears are changing toward a new sort of technology.
