2. Caching Yields Stale Data
False: Server consolidation is all about having a highly available, manageable and reliable – not
to mention auditable and compliant – place to store data.
The problem is users aren’t in the
datacenter, and the network that connects them, be it the WAN or the Internet, is far from perfect.
One solution would be to put an appliance with a file server in it, such as Linux Samba, as part of
an optimization solution. That works, but undoes much of the simplicity and compliance benefits of
server consolidation. A better plan is to mirror only the data that users need, just when they need
it. Caching dynamically sorts out the most popular web, video and file share data automatically. And
because it’s not an authoritative or searchable source, you don’t have to worry about keeping it up
to date or ready for the auditors or lawyers to go trolling through.
3. Optimizing Packet Data at Layer 4 Will Yield High WAN Performance
False: Packet delivery is already highly optimized – and works pretty darn well. If you’re still having
application performance problems, the problem probably lies where the applications live, up at
layer 7. The problem is changing application behavior requires a bunch of things. First, it requires
intercepting applications and having an idea of what’s going on and providing that visibility to the
