The deluge of WAN accelerators from Cisco, Riverbed, Juniper, Expand, Packeteer,Bluecoat, Silverpeak etc. etc. is proving good for datacenters. Not sure how many vendors will remain viable in a year or two, but the selection at the moment is decent.
I’m not known for retractions and I’m not posting one. I did however check out the new DD boxes and the really big ones are far more capable than the old ones.
I use my laptop so much that I sometimes forget about some server-type tunings.
I resuscitated my hot-rod AMD box – it’s a grossly overclocked monster but only has 1GB RAM (since it’s hard to find that kind of fast RAM in bigger sizes, and using 4 sticks prohibits me from overclocking it so much). Let’s just say the CPU is running a full GHz faster than stock, and with air, not water or peltier coolers.
One subject I keep hearing about is deduplication. The idea being that you save a ton of space since a lot of your computers have identical data.
One way to do it is with an appliance-based solution such as Data Domain. Effectively, they put a little server and a cheap-but-not-cheerful, non-expandable 6TB RAID together, then charge a lot for it, claiming it can hold 90TB or whatever. Use many of them to scale.
