I know the p5316 is not supported but is there a 64k iu command for the ext4 file system?

Hello Sklise,

Thank you for contacting Solidigm™ Support.

I want to inform you that we do provide support for SSD-P5316 and all available commands can be located using CLI Solidigm™ Storage Tool.

Supported Ext4 file system distros.

Linux:

Red Hat Enterprise Linux (RHEL) 8.0, 8.2, 8.3, 8.4
CentOS 8.0, 8.2, 8.3, 8.4
SLES 12, 15
Ubuntu 16.04, 18.04, 20.04

ESXi:

ESXi 7.x
ESXi 8.0

Notes:

On Linux systems, the tool must be run with root privileges. This can be done through either
sudo or su commands. If running as a non-root user, the tool will not be able to communicate
with the drive. Only basic drive information will be displayed; no drive functions will work.

There are two Linux installers: one for 32-bit systems, and one for 64-bit systems.

On ESXi systems, the tool only works on PCIe NVMe drives using the Intel ESXi NVMe driver.
The user will need to set their ESXi host acceptance level to “CommunitySupported” in order to
install the tool.

Namespace limitations on RHEL/Centos 8.2: Kernel bug can cause deadlock on delete
namespace in RHEL/CentOS 8.2.

Earlier OS Versions not listed in the supported list are generally expected to work but are not
actively validated and not officially supported.

As well P5316 is 64k native LBA size/sector size is the same for our drives, the P5316 has 512 & 4096 Bytesand, due to the drive’s larger indirection unit(IU) of 64KB. Anyone using these SSDs should be sure that their software accounts for this, it’s suggested best practice to issue writes that are IU aligned.

Please let us know if you have any other questions or concerns. Remember that you can always contact us via our Support HUB.
