The technical support team can add an extra SSD. For installing the drive, we need to shut down your server (downtime ~ 30 min).
If as requested we have added the drive to the server and restarted it. You can format the filesystem and add drive to your OS. In this case Ubuntu server.
NVMe (Non-Volatile Memory Express) is a specification for accessing drives through PCI Express; it is tailored to meet the needs of non-volatile memory. For example, the connection via PCIe Gen3 x4 (32 GBit/s) provides five times faster access speed and lower latency than the traditional SATA 3 (6GBit/s) interface. Due to the high degree of parallelism and low energy consumption, they allow users to meet current and future memory needs.
