Highly Virtualized

Users simultaneously boot their virtual desktops in the morning resulting in traffic spike

Each desktop session tends to use as much bandwidth as possible for better QoE

Desktop are small VMs deployed in large numbers, the endpoint density clutters management

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

How about Security?

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 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 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)?
