Internet Traffic Management: From Chaos, Order June 12, 2000 By David Newman NetScreen Technologies NetScreen-5  Don't be fooled by the size of the NetScreen-5. It's only as big as a paperback novel, but it offers bandwidth management and complete firewall and VPN gateway implementations. The unit is small in price, too: At $995, it is by far the least expensive unit we tested. NetScreen offers 10- and 25-user licenses for the NetScreen-5. We were unable to test the device with 200 concurrent users, as we did with other products, but it's intended for the SOHO market, where there are seldom more than a handful of users. Although the NetScreen-5 offers fewer bandwidth management knobs than the others provide, test results show it still does a more than adequate job of traffic shaping. The NetScreen-5 posted a first-place finish in our rate-control tests and also fared well in our tests of mixed-class traffic handling. The NetScreen-5 can be set up and managed from Web or command-line interfaces. Both interfaces offer three ways to control bandwidth: a guaranteed level, a maximum level and a relative priority level. The device does not offer explicit control over individual connections within a given policy. One minor nit: The NetScreen-5 offers interfaces that run only at 10 Mbps, and not at 10 and 100 Mbps. Given that the external interface for this device will almost certainly be connected to a low-bandwidth DSL or cable modem link, the 10-Mbps speed limit isn't a major problem. Still, a few routers, switches and hubs with 100-Mbps-only interfaces are available, and it would be helpful if the NetScreen-5 could be attached to them.

Data deduplication: Declawing the clones
Data deduplication is emerging as a critically important new arrow in the storage administrator's quiver to answer hard questions about the increasing problem in storage growth costs.
Compression, Encryption, Deduplication, and Replication: Strange Bedfellows
One of the great ironies of storage technology is the inverse relationship between efficiency and security: Adding performance or reducing storage requirements almost always results in reducing the confidentiality, integrity, or availability of a system.
