Customer Projects

Some representative projects that I've worked on can be seen here.


NJ DORNJ Dept of Revenue ( NJ Treasury )  VMware, and SAN build

NJ Treasury staff had no in-house VMware experience.

 4AERO Lab Environment

CLICK ON IMAGE for more details.

I maintain a physical vSphere lab environment.

The environment currently supports vSphere,  Horizon View (remote desktop), NSX
vRealize Operations, and vRealize Automation, VDP backup

Hosts: 2 x ESXi 6.5,  vCenter 6.5
Storage:  primary: FreeNAS ZFS ( SAN and NAS ),   backup: Thecus NAS
Security:  pfSense virtual Firewall,  NSX firewall

Testing loads:   FreePBX (telephone voice),  Plex video / DVR
                         Squeezebox music server, Virtual desktops, Web, DB, and Mail servers




Cloud Environment:  I maintain various VM's migrated from above environment into Amazon EC2 VPC
environments for learning EC2 and testing migration steps.
Migration testing has included a mulit-tier load-balancer web server environment,  and FreePBX.

Cloud Backup:  On-site ZFS snapshots are replicated ( with native ZFS send ) to a cloud service supporting ZFS.
Since ZFS snaphots in FreeNAS are integrated with vSphere a vmtools quiesce occurs and consistent snapshots are produced.
