Case Study: CLSA Asia‑Pacific Markets achieves LAN‑speed email worldwide and 35% cost savings with Riverbed WAN optimisation

CLSA sees fast application responses and LAN-speed email worldwide with Riverbed WAN optimisation solutions from BT

CLSA Asia‑Pacific Markets is a leading independent brokerage and investment group headquartered in Hong Kong with more than 1,500 professionals across Asia and global offices. Seeking to cut costs and create a more agile IT infrastructure, CLSA consolidated over 20 Microsoft Exchange servers into a Hong Kong data centre, but found email delivery and application response times degraded over the WAN—threatening the fast information access its clients expect.

BT deployed Riverbed Steelhead WAN optimisation appliances (a rapid trial in the worst‑affected offices followed by 32 appliances with redundant MPLS links and dual Riverbed management consoles) to accelerate traffic and eliminate repetitive transfers. Trials showed over 90% reduction in messaging volume and restored LAN‑like email and application performance worldwide; the centralised, BT‑managed solution delivered about 35% cost savings, avoided costly bandwidth upgrades and improved user satisfaction and IT productivity.
