NEWS IN BRIEF
Axtrinet announces APG Ethernet
Packet Generator software release
Axtrinet APG Ethernet Packet Generators are a cost-effective way of providing full
wire rate 10Gbps and 40Gbps Ethernet test capability in R&D and manufacturing
test environments.
Available in low cost APG4 or APG8 versions supporting 4 or 8 ports of 10Gbps
and with an additional 2 ports of 40Gbps available on the 8 port APG208 the
Axtrinet Ethernet Packet Generators provide full wire rate packet generation
and reception on every port. Ideal for Ethernet performance testing, an Ethernet
load generator in an R&D lab, or as part of an automated test solution in a
manufacturing test environment.
Axtrinet Ethernet Packet Generator Software Release V2.0 offers the additional
features:
•
•
•
•
•
•
QSFP+ ports can be configured as 40Gbps or 4x10Gbps
Multi-Burst Transmit Mode and Packet per Second Transmit Rate
Optional Port ID, packet sequence number, transmit and receive timestamps
(to ±8ns resolution) for latency and jitter measurements.
Up to 1GB ‘deep’ buffer available for line-rate packet capture at 10Gbps and
40Gbps
Save captured data to PCAP file for analysis in Wireshark.

Container storage
for Kubernetes Pods
Excelero’s NVMesh server SAN now supports
persistent container storage for hyperscale
architectures utilising Kubernetes. This makes
use of pooled, redundant NVMe storage in
container applications requiring persistent
volumes, allowing enterprises can obtain both
local flash performance and container mobility
at data centre scale.
Scalable and persistent container storage
is a top pain point for many infrastructure
architects and developers who want to embrace
microservices style deployments, but require
more performant approaches than NFS or
persistent volumes on traditional all-flash-arrays
(AFAs). They want the local performance of
flash but the flexibility and data protection of
centralised storage. The new NVMesh capability
uses Kubernetes’ advanced orchestration layer
to deliver pooled NVMe with local latency and
performance. With this approach, containers in
a pod can access persistent storage presented
to that pod, but with the freedom to restart the
pod on an alternate physical node.
Excelero’s NVMesh 100% Server
SAN platform further benefits container
deployments with its approach by shifting
data services from centralised CPU to complete
client-side distribution. It virtualises the
NVMe devices and unifies the capacity into a
single pool of high-performance storage in an
approach that makes data locality irrelevant;
a breakthrough in enabling local latency
and speeds on the network, using standard
hardware. Since NVMesh doesn’t impose a
‘CPU tax’ on targets sharing NVMe drives, it
allows for complete converged deployments
without the normal SDS penalty. This allows
NVMesh to scale performance linearly at near
100% with a virtual, distributed non-volatile
array without requiring additional dedicated
storage servers or appliances. n
