2008 to date: Brocade
Joined Brocade through the acquisition of Foundry in late December 2008.
Completed basic Fibre Channel training and 8 Gbps FC/basic DCX training in
Remained part the IP/Ethernet SE organisation but added FCoE and Ethernet Fabrics as areas of competency.
Won a new project for City based finance client's network, Insight Investment, just prior to the Brocade acquisition of Foundry, which included Foundry Brocade BigIron RX core LAN switches and Brocade DCX SAN directors (product ranges of both the acquiring and acquired companies). Initially won the contract to replace the existing core but went on to replace the entire network edge and therefore displacing Cisco completely from the network.
Took a lead roll in promoting and winning Brocade Ethernet Fabric customers in 2010, including a major Data Centre with Linklaters and deployments with several media companies in Soho, London (e.g. Moving Picture Company, Rushes, Deluxe etc.). My association with MPC has been a long one, since first working on the project for their core BigIron RX router in 2006 and going on to provide them with VDX switches, including the VDX 8770 chassis to replace the BigIron RX in 2014.
Ran Networking Academy session for Brocade IP/Ethernet Partners/VARs, presenting on MLX Technical Deep Dive.
Won a Sales/Pre-Sales Incentive Prize in 2011
for the highest revenue for Ethernet Fabric in the UK (an engraved high end
Personally managed, organised, configured and installed the network for the first major hosted Microsoft services (Lync, Exchange, SharePoint) deployment in the UK in 2011 for Sipcom, with VDX Ethernet Fabric switches and ADX Application Delivery Controllers. Won a Brocade Button Award with a citation from Microsoft for this work.
Won a major new Data Centre deal for Friends Life in 2012 with TCS (Tata
Consultancy Services) in a very competitive environment with extremely tight
timescales. The design used used an innovative 2 tier architecture with an
Ethernet Fabric based on Brocade VDX switches and a routing core based on
MLXe-16 switches running VRFs for security isolation. The Cisco design and
BOM for this project was completed before our first meeting and there were
only 5 months left until the DC would go live and provide data and services.
Nevertheless, this became another new business win for Brocade.
Ran an online webinar for Brocade IP/Ethernet Partners/VARs on NAS, iSCSI and VDX Integration.
Won SE Of The Year Award in 2012. Given 10 Year Long Service Award in 2013.
Underwent full Challenger Sales training, in four stages and, using the 4K UHD movie post production campaign as a real customer example, awarded Challenger Champion status at the Sales Kick Off conference in San Jose 2014.
Following the take-over of Insight Investment by BNY Mellon, with a Cisco
corporate standard, continued and expanded the trusted-advise relationship
to win a project to replace the existing network with VDX 8770 chassis
Won a Contribution Award in 2016 for handling the IP and Ethernet Fabric elements of the ESMCP (Emergency Services Mobile Communications Program) project, involving an order for over 100 VDX switches, with Motorola Computacentre and EMC
