Led a team of seven engineers to develop standards and provide level 2 & 3 support for server, VM and Operating System environments.Coordinated with multiple teams to successfully migrate nearly 4000 assets (VMs and bare-metal servers) from our former Jersey City office to a colocation in Clifton, NJ. This migration effort spanned much of 2017 and included.

Designed modern solutions to help consolidate existing workloads by leveraging current PowerVM technology which improved UNIX environment upkeep and deployment strategies.Implemented multiple Shared Storage Pool (SSP) Clusters across IBM Power8 Scale-Out servers. This allowed for Live Partition Mobility (LPM) and rapid deployment of new Lpars. It also.

• Built the company’s entire AIX stack from the ground up on 3 Power7+ 770s (9117­MMD) for Manhattan’s WMOS(DMS), Oracle JDEdwards(JDE), Enterprise Order Management(EOM), and the IBM Integration Bus(IIB).
• The virtualization layer on each 770 consisted of 4 Virtual I/O Servers (2 for PCI and 2 for Non­PCI) for a total of 12 VIOS partitions.
• Network virtualization was provisioned through a Shared Ethernet Adapter Failover with Load Sharing setup, which allowed us to distribute our network traffic across the pair of VIOS. VLAN tagging was enabled to provide.
• All storage was provisioned across N­Port ID Virtualization(NPIV) on IBM Storewize V7000 and EMC VNX for Non­Production logical partitions; EMC VMAX for all Production lpars.
• Provisioned all V7000 storage for all Non­Production Lpars.
• Maintained mksysb images embedded with storage drivers (PowerPath for EMC & SDDPCM for V7000) on a central Network Installation Manager(NIM).

• Provided AIX recovery services for client with a failed storage subsystem through the use of Network Installation Manager and mksysb images. Created external volume groups and filesystems in preparation for backup.
• Physical installation of various IBM Power 7+ express models into customer environments. Performed initial installation and configuration of IBM Virtual I/O Server including N­Port ID Virtualization, Network Interface.

• Lead the AIX/Oracle migration effort of 30+ Power5 Lpars in a New York based datacenter to Power7 servers in Columbus, OH. Provided detailed documentation of application shutdown and startup procedures prior to the.
• Provided detailed IBM Power7/AIX solutions for customers looking to refresh their current IT Unix environment through econfig and MS Visio.
• Performed custom benchmarks for clients in the Business Partner Innovation Center to compare IBM Power 7 servers against competitive hardware. Benchmarks were performed with a mix of tools: IBM nstress package (ndisk.
• Developed and implemented a procedure to perform a Bare Metal Recovery of multiple RedHat Enterprise Linux servers running under a Power 5 AS/400 Lpar to individual Power 7 Lpars running over a dual VIO server.
• Implemented multiple PowerVM networking strategies utilizing Network Interface Backup(NIB) and Shared Ethernet Adapter Fail­over (SEA Fail­over) with VLAN tagging (IEEE 802.11Q).
• Worked with customers to implement new IBM PowerVM technologies on various Power 7 servers (720/730/750/770) utilizing VIO, NPIV, VSCSI, IBM Storwize V7000 (storage virtualization).

• Implemented PowerVM on all existing IBM Power5 servers allowing for higher utilization of the hardware. Installed dual VIO servers with SEA and vscsi on each (3) p570, (2) p550, and p520 without the need to purchase.
• Performed OS upgrades on lpars running AIX 5.1­5.3 to AIX 6.1 TL6 with the use of Alternate Disk Migration(ADM) and Network Install Manager(NIM).
• Migrated 30+ lpars from IBM DS4700 and DS6800 storage to EMC VMAX with the use of AIX LVM at zero downtime to the running applications and clients.
• Development of PHP/Perl based web applications for filesystem monitoring, performance monitoring, and account administration. Later converted some applications from Perl to Ruby to improve on speed, length, and code.
• Executed the migration of an existing Oracle Retek Data Warehouse to Netezza Database Appliance with the use of Wisdom Force FastReader.
• Responsible for the upkeep and maintenance of all UNIX servers, administration of user accounts, storage administration, performance tuning, and backups.

Armonk, New York, NY, US

• As pSeries floor lead, provided the assurance of a complete and accurate Disaster Recovery setup, managed the implementation and upkeep of new and existing pSeries hardware, and utilized Korn Shell to develop.
• In preparation of a Disaster Recovery exercise, replicate a customer's complete hardware/OS environment (including SAN and network infrastructure). This often involves the recovery of a customer's MKSYSB/SYSBACK image.
• During a recovery event, provide support to customers who may need assistance configuring system devices. Often times, this included the configuration of network interfaces, and tape libraries such as IBM’s 3584 and.
• Configure Storage Area Networks on both Cisco and Inrange SAN directors, as well as Local Area Networks on Cisco switches. Many customer environments required the configuration of storage arrays on devices such as.
• Written extensive procedural documentation on the setup, configuration, and breakdown of new equipment and technologies including the STK 2500 Disk Array and POWER5 VIO LPARS. Trained novice system administrators in.
• Provide unix support to the Sterling Forest Sun/Solaris team. Utilized Korn Shell scripting to help automate the Jumpstart installation of Sun Servers.
