Case Studies

Chinese Branch Office VPN

Our client opened a branch office in Shenzhen, China and wanted employees there to have access to their ERP. Unfortunately, the "great firewall" of China made remote connectivity slow and unreliable. EMKAL worked with a vendor in Hong Kong to implement a new internet connection with an IPSec VPN tunnel on a Cisco router, enabling Chinese operations to reach full production capacity.

Great Wall

VMWare Virtualization and Scaling

Upon auditing a new client environment we discovered their primary server was operating on workstaition-class hardware in an unventilated service closet with no RAID or redundant power supply. We provisioned, configured, and deployed a Dell R720 server with VMware vSphere, then migrated all critical line of business applications with zero downtime. We were later able to virtualize a Microsoft Domain Controller and a 3CX VoIP Server, while simultaneously deploying a 100 Mbit synchronous fibre optic internet service with SIP trunking and QoS. As a result our client was able to triple the size of their call center operation without adding additional hardware.


Network Infrastructure and Apple iPad Deployment

Our client had a vision to place dozens of iPads in the hands of children in their care. We transformed five disconnected educational centers into a single network managed from the head office using IPSec VPN Tunnels. We set up and installed Netgear PoE switches, Ubiquiti edge routers, and UniFi Wireless AC (IEEE 802.11ac) access points, while project-managing third-party vendors to install enterprise grade 12U rack mount cabinets, faster internet and additional CAT6 network wiring.


Troubleshooting A Deep Software Bug

A third-party vendor needed to install their application on our client's systems. The software worked on many machines, but a few were generating an error when clicking a certain button. This was a long standing problem for the developer and they had been unable to determine the cause. Using advanced tools like Microsoft Process Monitor, we were able to get to the root of the problem. The third-party vendor implemented our patch, benefiting both our client and users of the software worldwide.


Live RAID Migration and Cache Upgrade on Hewlett-Packard Production Server

Our client was experiencing slow access to their main application server. Using a combination of Windows Resource Monitor and Atto Bench32, we identified the root cause as poor disk performance. We discovered the RAID adapter for the HP DL360 server did not ship with a Flash Backed Write Cache (FBWC) module and 3 of the 5 installed disks were not in use. We sourced and installed the cache module, then flashed the server firmware before performing a live migration from RAID 1 to RAID 1+0 (plus hot-spare). The result was 20x faster disk performance from the same hardware.

Custom Label Printing Software Development

A client with an aging infrastructure depended on a single workstation running Windows 2000 for Workplace Hazardous Materials Information System (WHIMS) label printing. We developed custom software, using ASP.Net on IIS, to generate and print labels using the latest version of Windows Server. Migrating to a Virtual server and enabling multi-tenant access to the printers eliminated the single point of failure and increased operating efficiency.
