Why should a customer avoid using swap on SSD and NVMe disks?

Although swap is generally recommended for systems utilizing traditional spinning hard drives, using swap with SSDs can cause issues with hardware degradation over time. Due to this consideration, we do not recommend enabling swap on DigitalOcean or any other provider that utilizes SSD storage.

Should I make a swap partition on SSD?

Placing swap on an SSD will result in better performance than placing it on an HDD due to its faster speeds. Additionally, if your system has enough RAM (likely, if the system is high-end enough to have an SSD), the swap may be used only rarely anyway.

Should I use RAID with NVMe?

NVMe Software RAID – This setup is highly recommended if you’re using local storage on a system. Software-based RAID can use the processing power of the system to handle RAID configuration. NVMe Hardware RAID – Hardware-based RAID requires a dedicated controller installed in the server.

Can you hot swap NVMe drives?

The NVMe PCIe SSD supports orderly hot swap allowing you to add or remove a device without halting or restarting the system in which the device is installed.

Is swapfile better than swap partition?

The primary advantage of a swapfile is that it is easy to resize, so there isn’t much point in transitioning unless you are unhappy with your swap partition size. You could move the swap to an encrypted partition for security, but there are other ways of encrypting your swap.

Can NVMe drives be raided?

RAID works on NVMe SSDs just like it did on previous storage devices. Linux mdadm supports NVMe RAID and has enhancements to improve reliability, performance, and scalability. There are independent hardware vendors that support NVMe based RAID cards for hardware acceleration as well.

Does 16gb RAM need a swap partition?

If you have a large amount of RAM — 16 GB or so — and you don’t need hibernate but do need disk space, you could probably get away with a small 2 GB swap partition. Again, it really depends on how much memory your computer will actually use. But it’s a good idea to have some swap space just in case.

How do I change the NVMe drive?

Swap the new NVMe drive in place of the original one. Boot the system from the Reflect recovery flash drive (F12 at powerup with it connected) and restore the image to the new drive. Shut down, disconnect the external drive and remove the recovery flash drive. The system should then boot correctly from the new NVMe drive. 05-17-2018 06:18 AM

How do I upgrade to NVMe from reflect recovery flash drive?

Boot the system from the Reflect recovery flash drive (F12 at powerup with it connected) and restore the image to the new drive. Shut down, disconnect the external drive and remove the recovery flash drive. The system should then boot correctly from the new NVMe drive.

What is NVMe storage?

NVMe Storage Explained Non-Volatile Memory Express (NVMe) is a new transfer protocol designed for solid-state memory. While SATA (Serial Advanced Technology Attachment) remains the industry standard for storage protocols, it wasn’t built specifically for Flash storage like SSDs and can’t offer the same advantages of NVMe.
