1. World of HELIOS: Three times Intel, quad
CPUs, ...
Last summer we released HELIOS CD022, which contains all updates available at that time. It also includes brand new support for three additional HELIOS server platforms:
I ) Sun Server running Solaris 10 AMD
II) Mac Intel Server running Mac OS X 10.4
III) Windows 2003 Server
Today's quad CPU based systems, with more than 4 GB RAM, running HELIOS UB, blow away all previous server generations. There are only two major CPU platforms left: Intel/AMD x86 compatible and IBM Power5. This brings down the difference to the operating system (Solaris, Linux, Windows, Mac OS X, and AIX). I am happy that we don't have to choose between them because we support them all.
2. Sun Solaris 10 ZFS offers blazing filesystem performance
The new Sun ZFS filesystem introduces a previously unseen breakthrough in filesystem performance and management. All HELIOS UB based products and tools have successfully passed performance and reliability testing using the new Sun ZFS. Important tasks like working with many small files and re-indexing the HELIOS desktop database work much faster. Our engineers are delighted and we feel that the latest Sun options like support for AMD CPUs, offering OpenSolaris on multiple platforms – and especially the new ZFS – bring unmatched performance benefits for customers.

3. VMware Virtualization – deal or no deal?
Improved IT efficiency, consolidation, and lower costs through virtualization – this is the marketing buzz phrase these days. Are you real or already virtual? The HELIOS team is real, we built our HQ on real estate near Hannover, Germany, and we find VMware virtualization products really useful. We use VMware internally to test multiple client and server operating systems on a single box by launching the right VMware disk image. This saves time and is very easy to use.
However in production environments, under heavy load, things are different. CPU scheduling between multiple VMware operating systems does not always work as expected, networking performance is up to 70% slower (HELIOS LanTest), within minutes time can drift more than 200% on a virtual server, and sometimes the operating system freezes for a minute or so before it continues. This experience is real and not virtual.
Please check carefully how well a VMware solution might work for you. Don't forget to do intensive testing before deploying it. We feel VMware is a really cool thing and it works great for our support department. However, for heavy load servers in real environments, the real deal is needed.
