We tested final, gold code for Red Hat’s RHEL5 in a switched Gigabit Ethernet IPV4/IPV6 network comprising both DLink and HP switches.

We tested the code on numerous servers, including an HP585 (outfitted with 4-AMD Athlon dual-core CPUs, 12GB DRAM and an HP SCSI array), an HP DL140 (sporting dual 32-bit Intel Xeon CPUs and 4GB DRAM), a Polywell 2200S server (equipped with two AMD single-core Athlon CPUs and 4GB DRAM) and a Dell P280 (which had a single Intel Celeron CPU, 4GB DRAM; 500GB SCSI drive and Fibre Channel card).

We successfully tested connectivity via NFS4, LDAP and SAMBA, connecting with Windows 2003 Enterprise Server Edition, Apple MacOS 10.4.7 Server edition, Novell/SUSE Linux 10, as well as Windows Vista Ultimate/XP SP2, MacOS 10.4.7 client and NetBSD 3.

We tested Xen efficiency using LMBench3 on the same hardware (Polywell 2200 described above), first using a native SMP kernel, then a hypervised Xenified kernel and then using two DomU kernel guest instances. We saw linear performance degradation across the results.
