Data Analytic Components - Urika-GX features a number of data analytic tools that help perform analytic
tasks, including managing and monitoring clusters, executing Hadoop and SPARK jobs, performing graph
analytics, etc. For more information, see S-3015, "Urika
®
-GX Analytic Applications Guide" and S-3010,
"Cray
™
Graph Engine User Guide".
●
Security and Tenant Management Tools - Secret files used on the system are managed by the Urika-GX
Secret Manager. Tenancy is implemented through the use of a tenant VM that runs on physical nodes and
provides controlled access to services on the physical nodes through a command proxy mechanism. For
more information, refer to
on page 177 and
on page 183.
NOTE: Only Spark and HDFS commands can be executed within a tenant VM in this release. All the
commands for flexing the cluster,
mrun
and Cray Graph Engine (CGE) CLI commands cannot be
executed within a tenant VM.
In addition, Urika-GX features a number of CLI scripts that facilitate system management and monitoring the
system.

Network Components
There are 3 networks deployed on the Urika
®
-GX platform:
●
Aries High Speed Network (HSN) - The Aries HSN provides high speed application and data network
connectivity between nodes. This network provides node interconnect via high bandwidth, low latency DMA
access. The hardware to support this network consists of an Aries Interface Board (AIB) connected to an
available PCIe slot on each Urika-GX node and integrated into the node chassis assembly. The AIB is
connected to the dANC integrated in the Urika-GX sub-rack. Copper cables provide an all-to-all connection of
all dANCs in the system.
●
Operational Ethernet network- The operational Ethernet network is used for ingesting user data. This
network is comprised of a single unit 48-port GigE switch that provides dual 1GigE and/or dual 10GigE
interfaces to the site network. Urika-GX's login nodes do not route through this switch and need to be directly
connected to the site network. The operational network allows node connectivity externally from Urika-GX to
the site network. The Urika-GX compute and I/O nodes are connected to a single managed Brocade ICX
6450-48, 48 port switch with a single power supply. Connectivity of this network to the site network is made
possible by two available Gigabit Ethernet ports and/or two 10 Gigabit Ethernet ports on the ICX 6450-48
switch.
The operational network can also be used to access data streaming applications and services directly from
compute nodes.
●
Management Ethernet network - The management Ethernet network is primarily used for system
management, and not for user data. The management Ethernet network is comprised of two stacked 1U 48-
port switches, which are located at the top of the Urika-GX rack, and can optionally contain redundant switch
power supplies. These switches provide GigE management Ethernet connectivity to every node, System
Management Workstation (SMW), Rack Controller (RC), Intelligent Subrack Control Board (iSCB), Power
Distribution Units (PDUs), Dual Aries Network Cards (dANCs) and to the operational network that connects to
the nodes.
The Urika-GX system also contains the following subnets:
○
SMW subnet, which provides connectivity to the SMW and the RC.
○
Rack subnet, which provides connectivity to the dANCs and iSCB module.
This network is supported by two managed Brocade ICX 6450-48, 48 port switches stacked together with two
10gigE optical interconnects. Each switch contains a single power supply, and can optionally contain
