New features – general purpose
New CLI commands associated with the new features can be found in the configuration and operational commands section.
SSD scheduler configuration
This feature provides a way to configure scheduler option for Multi Queue and Non Multi Queue I/O schedulers.
I/O schedulers attempt to improve throughput by reordering request access into a linear order based on the logical addresses of the data and trying to group these together.
While I/O schedulers may increase overall throughput, it may lead to some I/O requests waiting for too long, causing latency issues. I/O schedulers attempt to balance the need for high throughput while trying to fairly share I/O requests amongst processes.
Support SR-IOV (accelerated networking) in Azure
This feature adds support for SR-IOV, also called accelerated networking, in Azure for greater network bandwidth performance.
Display BGP per-neighbor route-map deny counter
This feature adds an in-bound drop counter for prefixes excluded by a configured route-map.
Stateful firewall override
This feature allows SNAT/DNAT rules to be configured so that they do not automatically install a pinhole for return traffic matching the NAT sessions.
This means a user can have a firewall configuration that affects traffic matching a NAT session.
Add trim support
This feature provides a way to discard, or trim blocks that are not in use by the file system.
Trim support is useful for solid-state drives (SSDs) and thinly-provisioned storage.
