2.3.2.2
Ultra Low Latency Driver (ULLD) for Linux
In Linux, the Nytro XP6500 uses an Ultra Low latency Driver (ULLD) which is optimized for achieving ultra-low latency
and scaling I/OPs. This ULLD exposes a new block device interface (
/dev/nytro-sdX
) in addition to the traditional
SCSI block device (
/dev/sdX
).
Both block devices represent the same underlying target, so there is a one-to-one correspondence for both the
devices and for partitions created on the devices, if any. You must use the ULLD device (/dev/nytro-sdX) for
applications and the traditional SCSI block device (
/dev/sdX
) for the Linux operating system installation on the
Nytro XP6500 card.
NOTE
Make sure you use only one interface at a time.
2.3.2.3
Creating a Driver Update Disk (DUD) on a USB drive
1.
Using the extracted files from the zip file from
Section 2.3.2.1,
Downloading the Drivers
extract the driver ISO from
DUD file using the following command:
