we are considering to buy a VMware Virtual Center.
We have two servers running VMware Standard edition.
Do you believe it will be worth it? Or do we have to
upgrade our VMware licenses to Enterprise before upgrading
virtual center to make it worth it. I had just read the
following article

I have been one of the lucky people who got to try VMware 4.0 beta. I have played with the VMware FT feature and it seems solid and a great addition to a great product in my opinion. If you still in doubt check out the sneak preview & video found at <a href="http://www.virtualizationteam.com/virtualization-vmware/vmware-esx-40-ft-fault-tolerant-sneak-peek.html" title="http://www.virtualizationteam.com/virtualization-vmware/vmware-esx-40-ft-fault-tolerant-sneak-peek.html" target="_blank">http://www.virtualizationteam.com/virtua…</a>
which will get you nudging your head and ready for the release of VMware FT.

Enjoy,
Virtualization Master

What I find interesting is the limitations to these software FT products. I did sit in on the VMware FT session that was held right after Tuesday mornings keynote by Paul Maritz. The room was very large and it was practically full, so there certainly was some interest. And the person who gave the presentation I thought did a great job of not “marketing” this as the answer to every availability problem out there. The fact that there is no release date or no pricing was a bit disconcerting, I have heard a few different dates and those keep shifting (and not in a good way). One of the big issues that you have with software FT is the inability to scale. This is true with the Xen based products and it seems to also be true with VMware. Applications can not span past a single core. This is a “nut” that no one has been able to crack to this point. Now that may not be an issue as long as the application you want to run in FT (mode) doesn’t need more horsepower then a single core can provide. The problem there is that it’s difficult to know this, and worse, we all know that peak times cause spikes and with the overhead that VMware is stating (could be as high as 20% in worst case), performance could become and issue very quickly. Another significant issue with software lock step, is latency. The “roundtrip time” required for tasks like replication, heartbeat, and replay adds to the amount of time required to process a transaction and can not be solved by simply over-configuring a server with additional resources. These software FT solutions also require two (2) servers, each configured with a copy of the software plus duplicate copies of all the guest operating systems and applications that require protection. So ultimately, the need to “double-up” on the amount of hardware and software the IT group needs to purchase and manage is contrary to one of the central reasons virtual environments are deployed in the first place. Add to that, there are inherent requirements for redundancy, networks, and storage in the architecture of VMware FT such that it may require the modification of you configuration, although the application itself does not require any modification. This all begins to add up to complexities and cost that you uncover as you implement what was supposed to be a “cheap & simple” solution.
