The next raft of Sun Microsystems Inc Netra Internet servers are to be unveiled tomorrow, Tuesday, today’s Unigram.X reports. There are three new models: the Netra i 4000 and i 5000 are Ultra Enterprise 4000 and 5000 boxes with Internet extensions, and the Netra i 2/120 is based on the two-way Ultra departmental server. The servers come with Netscape Communications Corp SuiteSpot Internet software, and added Sun security features such as virus scanning, firewall and intrusion detection software. The Net Server 3.1 family ships before year-end. Once again with the Netra servers, Sun thought it best not to issue any prices, and they will come later in October. And as for when Sun’s own Web server suite, code-named Vishnu, might be bundled with the Netras, Netra product manager Raj Sehgal claimed to not even have heard of Vishnu. Sun claims the two-way 2/1200 performs up to 626 operation per second based on SPECWeb96, compared to 305 for the 1/170E. Netscape is said to be running a 2/ 1200 that’s handling up to 17 million hits a day from its Web site.
