Confidential

Senior Systems Engineer

Responsibilities:

• During his tenure at Confidential (PTG), Ernest has installed, configured, and maintained several NAS and SANs comprised of NetApp, Confidential, Brocade, SUN, and IBM hardware. Specifically, he has installed, configured, and provided performance tuning on the NetApp FAS 3020 filer (NAS device) for NFS and CIFS connectivity, as well as, Brocade FC switches in the IBM Blade Centers for SAN connectivity. In addition, Mr. Flowers was responsible for several CLARiiON FC and CX arrays, and many SUN StorEdge arrays. His duties were to provide storage allocation, LUN assignments, break/fix services, creating and mounting file systems, and path management to a myriad of hosts through a Brocade Fabric consisting of workgroup level switches, such as the 3x00 and 4x00. Ernest was the point of contact for Veritas NetBackup. Ernest was responsible for gathering requirements and creating an implementation plan, which were key components in developing a storage and BURA infrastructure.
• Ernest was a vital link in a group of multiple engineering teams that designed, tested, troubleshot, performed kernel debugging, installed, configured, deployed, upgraded, and supported complex collection systems, which encompassed system hardware, operating systems, storage, archiving, and networking. In this organization, his primary duties were to maintain, integrate, analyze, and perform failover testing for the server environment as well as identify and resolve all issues in a timely manner. These responsibilities resulted in several OCONUS tdy’s. During his travels, Ernest received glowing exit reports on his performance and professionalism while at remote sites, which is due to his skill in authoring system and software configuration guides and user’s guides that he used as reference tools. During downtime, Ernest attended RedHat 5 and VMware Infrastructure 3 classes where he took both tests and passed each with high scores becoming a RedHat Certified Technician and VMware Certified Professional.
• In Ernest’s earlier years at PTG, he was a member of a small team of engineers who were tasked with architecting a virtual data center, which was contained within a single rack built around the IBM BladeCenter. Ernest created VMware guest Operating Systems as Resource Groups within Veritas Cluster Server 2.2 running on multiple Blades and connected to shared file systems on a Sun StorEdge Fibre Channel Array. He was able to deep dive into storage and networking in VMware using Fibre Channel storage, multipathing in Fibre Channel SANs, raw disk usage, and maximizing virtual machine disk availability and performance. He was considered to be the on-site IBM BladeCenter expert/consultant at the government site where he was responsible for assembling, installing, and maintaining the IBM 8832, 8843, and 8850 blades. The installation, configuration, and firmware updates of the Cisco Intelligent Gigabit Ethernet Switch Module (CIGESM) and Brocade Switch Modules of the IBM BladeCenter were performed by Mr. Flowers upon his receipt of the hardware. He chose to install and configure IBM Director 5.10 with Remote Deployment Manager 4.20 Update 3 to provide systems management. IBM Director was used to push firmware updates to the IBM BladeCenter Chasis, Blades, and Management Modules. Configuring an external Cisco 3750 was an important step in his networking configuration because it allowed multiple VLANs for communicating with the management modules and CIGESM of the BladeCenter. After ensuring the hardware and environment were set up, Ernest installed the Operating Systems, which included VMware 2.5.2, Red Hat Linux ES/AS 3 Update 5, and Red Hat EM64T (64-bit) using Red Hat kickstart initiated as separate IBM Director tasks. There were times when he would manually install, configure, and implement VMware ESX Server 3.0, virtual machines running Red Hat Linux ES/AS 3 Update 5, DNS, Veritas Cluster Server 4.0, and various software applications. Finally, Ernest met with and provided a status to the government as a technical interface between them and the vendor, and worked with vendors to report hardware failures and request replacement parts.

Sr. Solaris Systems Engineer

Responsibilities:

• Ernest installed and supported Confidential PowerPath and Navisphere 6.0 Solaris Agent, QFS 5.0, and Tripwire on Sun V210’s, V440, and 480R’s connected to CLARiiON fibre channel arrays. The support provided included performing benchmark testing and documentation of SAN disk I/O. Ernest also provided upgrade support, public key for SSH authentication support, and resolved NIC, HBA, failed disks under SDS control, and DNS issues in a high availability and mission-critical environment. Furthermore, Ernest built Solaris Jumpstart boot servers, which were used to install additional new servers and performed Operating System and software troubleshooting, research and development, and shell scripting. Standardizing and documenting a console logging solution capable of capturing all serial port activity was also tasking Ernest received and successfully completed. Finally, Ernest tracked all service requests and changes via Remedy to ensure a complete project cycle. As with most projects, there was documentation requirement, a part of Ernest’s role was to write documentation for transitioning control of systems, SANs, and network equipment to another organization for administration.

Part of his day to day duties were to perform routine UNIX systems administration tasks, such as disk installation and partitioning, disk space cleanup, revising disk backup schedules based on volume, modifying Apache Configuration files, managing the NetApp Filer, and locating and cleaning up defunct processes. He designed standard implementation on backup/recovery, archival systems, and disk arrays. He acted as the first point of contact on a team of three UNIX administrators, resolving problems and concerns of users and Project Managers for all hosted web sites, where he ensured that system downtime never fell below 99%. Ernest has conducted team training, provided technical assistance to the user community, and made recommendations to management that resulted in increased system efficiency. Building DNS servers, and installing BIND, NIS, system/software patches, and TCP wrappers were other responsibilities that were assigned to Ernest.
