Why is WAFS Important?
■ Remote Server & Storage Problems
–
Data and storage growth at the branch – hard to manage
■
■
■
–
Increased storage growth
Lack of control – compliance issues (SOX), versioning
Data at risk – poor backup processes (managing tapes)
Server management issues – costly, risky & inefficient
■
■
■
Limited IT expertise in the branch
Costly to administer and expand
Problems maintaining and fixing
■ Collaboration problems – Sharing files between sites is
TOO cumbersome
–
–
Slow performance – CAD files, diagnostic images, Excel
spreadsheets & word documents, etc
Versioning control – managing last and best

Problems caused by Server Consolidation
and Collaboration
1. Microsoft file access performance problems
– Folders and file opens, saves are very slow
– CIFS over the WAN is very poor combination
2. Increased WAN traffic
– Impact to Windows collaboration
and
customer critical applications
(ERP, CRM, VoIP, etc)
?
3. Unexpected management overhead
4. Potential risks
– From file integrity to business continuity

iShared WAFS Implementation Overcomes
Consolidated Network Performance Issues
■ Addresses file sharing performance problems inherent in
CIFS oven the WAN
– Windows Common Internet File System
– Designed for LANs which have low latency, high bandwidth
■ iShared WAFS WAN optimization:
– Uses an optimized Transport that reduces “chattiness” of
Microsoft CIFS
– Leverages TCP acceleration and overcomes “slow-start” for
even better WAN performance
– Uses unique caching and compression technology to reduce
what does need to be sent over the WAN

iShared Performance Technology:
WAN-Optimized WAFS Transport
■ Six different techniques for file acceleration including:
–
–
–
–
Data streaming
Read-ahead
File-aware differencing
Clustered I/O
■ Eliminates hundreds / thousands of CIFS and NFS
■
■
messages going back and forth across the WAN
Eliminates redundant data transfer
Seamlessly interoperates with industry-standard CIFS and
NFS file sharing protocols

iShared Performance Technology:
TCP Acceleration

iShared Data Reduction Technology:
Caching and Compression
■ File-aware caching
–
–
–
–
File Differencing on writes/updates/repeat access
Sends only the changes
Delivers faster response and improved bandwidth utilization
Self-managing cache ensures best performance for frequently
accessed data
■ Application-intelligent caching
– Extensions for Microsoft Exchange (MAPI attachment caching)
– HTTP (static web pages)
■ Dictionary-based Compression
– Transmits references to repeated data blocks instead of data
– Compression ratios of up to 100:1
17
Dictionary-based Compression
■ Each end of the link maintains a ‘dictionary’ of datastreams
sent and/or seen
– New datastreams catalogued in the dictionary with a ‘tag’
assigned
■ Subsequent transfers of a common datastream don’t
require the physical data to be transferred
Data
Center
– Only a ‘tag’ telling the receiver where to locate the
datastream in the dictionary
