Challenges
As one of the largest healthcare services and products
companies in the world, Cardinal Health takes themanagement and protection of its corporate andcustomer data very seriously. With healthcare industry
data privacy regulations including HIPAA and HITECH
in place, the company must also address outsidecompliance issues. Cardinal Health recognizes thatvisibility into all of the data traversing its network is animportant part of both protecting its data andmaintaining compliance.
Initially, Cardinal used the Gigamon solution to address
challenges related to packet analysis, port conflict,and remotely routing traffic to the proper tools. Overtime, other groups within the company recognized thepotential of the capabilities of Gigamon and asked toleverage their solutions in additional ways. Gigamon
products now feed Cardinal Health’s application
performance monitoring, voice recording, and security
tools including a firewall from Palo Alto Networks usedfor threat analysis. The company also uses Viavi
GigaStor for packet capture.
Before Gigamon, if the monitoring team asked for
confirmation that specific TAP/SPAN traffic was being
delivered to their tools, the network engineering team
couldn’t provide a lot of detail for them. With Gigamonin place, the team can confirm the traffic in question
is being properly routed, and can provide metricsof interest. In addition, the company is overseeing a
multi-year migration to a 40Gb data center network, amassive project with a multitude of moving parts, bothliteral and figurative. Gigamon has been a key partnerin this endeavor and is helping Cardinal Healthmaintain visibility while the company scales its network
upwards.

SolutionThe original configuration at Cardinal Health involved
two GigaVUE-HD4 systems: one for each of their data
centers. Over time as their need for visibility from TAPs
increased, they added the GigaVUE-TA1 and GigaVUETA40 models. The GigaVUE TA Series provided higher© 2023 Gigamon. All rights reserved.

port density at a much lower cost when linked to their
GigaVUE-HD4 nodes. One challenge for their voicerecording project was that call SIP traffic and RTP
traffic could be sourced from separate data centers.
Cardinal Health added GigaVUE-HB1 nodes and used
GigaSMART tunneling between sites to capture theentire call session.

Results
With Gigamon, Cardinal Health has been able to speed
up time to resolution for a number of issues, including
both network and security-related challenges. Thecompany has also enjoyed lower costs by reducing
the number of tools they own and getting better
performance out of what they already have in place.
Consolidation is key to these savings. Gigamon
products are able to feed copies of the same traffic
to multiple tools for added efficiency. On the voicerecording side, the GigaSMART tunneling featureenables the company to seamlessly transfer the data
between data centers as needed while meetingcompliance requirements.
