Stromasys reports aim at speed, and help
The fine art and craft of tuning an Intel-based server to mimic HP's 3000 hardware has evolved. The Charon HPA emulator has been in production shops for more than three years. In the beginning, the software's demands on hardware were outlined in a table of preferred servers. Or in calls to a product manager. The latter has always produced more robust performance than the former. A recent string of messages on the 3000-L showed why. They also showed that a 3000 jobset that ran three times faster, after "setting power management to dynamic."
Performance tips on the L about selecting and tuning for the best hardware have included the following advice
Set other settings for performance
System Isochronous Mode enabled
Hyper-thread off or 1
Intel Speed Step enabled
If this set of instructions doesn't make much sense to a prospective user, it illustrates why Charon HPA is a fully-guided product by now. Customers and prospects buy services from Stromasys to deploy this solution. There's no other way. Downloadable freeware copies left the marketplace last year.
Emulating a legacy hardware server to run enterprise-grade applications is not a hobbyist's mission. Stromasys product manager Doug Smith says the customers have been better served with engineering-driven integration insights. He's got success statistics to prove it.The nuances of installing and integrating Charon for the success include networking deployment advice. Ray Legault, a systems manager at Boeing, shared these insights when another manager asked him about the impact of networks on Charon.
I did not perform any tests over the network. My actual servers are 1,800 miles away. In Linux, I make sure my ETH1 is set correctly.
ethtool -K eth1 rx off tx off sg off gso off gro off txvlan off rxvlan off
To avoid having to redo every time you reboot, just add this line to the bottom of the ethtool file:
post-up ethtool -K eth1 gso off gro off
So it looks clear that knowing Linux's ethtool will be an essential skill of integrating Charon, too. Expert services are now crucial for the product. That's why it's become a solution for the serious user, one trying to eliminate the need for 15-year-old HP hardware.
