• Network Operating System (NOS) Analyst for Alternate-OS support team handling escalated issues from Level 1 support, field engineers, and collaborating with other Dell teams such as Storage, Networking, and Developers to resolve customer issues• Typical escalations involve performance problems with storage & networking, PSOD’s, VM’s not starting, ESXi/vCenter disconnects, LUNs/VMFS disappearing, upgrades, configuring iSCSI (Dell EqualLogic/MD32xxi)• Tools used for resolving cases include engaging remotely via WebEx and phone, obtaining vm-supports to review logs/configuration/firmware/drivers, replaying performance data in esxtop to look for bottlenecks, capturing and analyzing network packets, extracting dump logs from vmkernel-zdump to help pinpoint issue• Limited customer’s downtime that was experiencing PSODs whenever a VM was powered on. The PSOD’s were showing up on random CPUs but the error always stuck with a particular slot (0-15 = 1st physical CPU; 16-31 = 2nd physical CPU). Since it was a single ESXi host there was nowhere to vMotion and put the host into maintenance mode. I ended up using CPU affinity to keep the VMs from using the affected physical CPU until a replacement CPU could arrive.• Used PowerCLI Image Builder to create customized ESXi 5 image with necessary drivers for customer having problems with the base ISO missing network and storage drivers necessary to complete install• Built vApp for vSphere: Optimize and Scale course for students to complete labs with including 2x ESXi VMs, 2x vCenter VMs, 1x Controller VM (File/DNS/DHCP/TFTP), and IP Storage VM.• Subject Matter Expert for Dell Management Plug-In for VMware vCenter (DMPVV) for automating hypervisor deployments, firmware updates, and host management.• Participate in after-hours phone support rotation with other L2s
