Perform ESD Prevention Measures
Perform ESD Prevention Measures
1. Prepare an antistatic surface to set parts on during the removal, installation, or
replacement process.
Place ESD-sensitive components such as the printed circuit boards on an antistatic mat. The
following items can be used as an antistatic mat:
■
Antistatic bag used to wrap a replacement part
■
ESD mat
■
A disposable ESD mat (shipped with some replacement parts or optional
system components)
2. Attach an antistatic wrist strap (not provided).
When servicing or removing server components, attach an antistatic strap to your wrist and then
to a metal area on the chassis.

Oracle 3.2 TB NVMe SSD Optimization Guidelines
To optimize preformance, observe the following guidelines when setting up Oracle 3.2 TB
NVMe SSDs in a server.
■
Block size can be configured through a server operating system or file system and is set to a
default size with Oracle databases.
■
The Oracle 3.2 TB NVMe SSDs is designed to provide the best performance for data
transfers that are multiples of 4k size and using addresses that are 4k aligned. Partitions
should be aligned to start on 4k boundaries.
■
The ZFS file system might require manual alignment. The Oracle 3.2 TB NVMe SSD has a
maximum transfer size of 128k. IO requests for larger transfer sizes are broken into transfer
sizes of size 128k or smaller. For optimal performance, transfer sizes should be limited to
128k to avoid additional overhead associated with breaking them into smaller transfer sizes.
■
The Oracle 3.2 TB NVMe SSD should be formatted using a label of type
EFI
(
format -e
command).
