Pluribus Open Netvisor Linux Fabric Introduction
“A computer cluster consists of a set of loosely or
tightly connected computers that work together so
that, in many respects, they can be viewed as a
single system”
ONVL Fabric is a software based, controller-less, fully distributed
and highly available server-style cluster of Ethernet Switches
Single CLI/API For Agility & Automation

13. How about Security?

14. Security begins with visibility
You can’t protect what you can’t see
Who is on the Network?
And what are they up to?

What Can You Answer With VCF IA? – Examples
1. How many concurrent connections were
open between Client A to Server B between
2am and 5am last week (EST)? Did it happen
before? Did client A try to flood other servers
at the same time?
2. What was the average connection setup
latency for the database server between 4pm
and 4:15pm when user X reported slow
responsiveness? How many concurrent clients
were connected at that time?
3. Are we load balancing LDAP servers as
expected? From which geography are most of
the connections to my servers originating?

18. 18 Dell - Internal Use - Confidential
What Can You Answer With VCF IA? – Examples
4. What switch ports are transporting the
most connections and are there any
packet drops or errors on these ports?
5. Is any of my secure servers being
accessed using unsecure protocols
such as telnet/http/ftp? Which client is
doing that?
6. How many times did user X connect
to foo.com in the past 36 hours? Did
anybody else behave the same in the
last four weeks?

19. 19 Dell - Internal Use - Confidential
What Can You Answer With VCF IA? – Examples
7. How many connections have been reset
(RST) and closed on server Z since 5am
today? Are these reset always associated to
a specific application?
8. Who are the Top Talkers for Application Y
on server Z since 2pm last Monday? And one
week ago when the engineering team from
our acquisition was still using the old server?
9. How many VM moves occurred on the
Nutanix cluster since last week? Was the
CVM unresponsive at any point in time
(SYN)?
