We are migrating from a series of old Linux servers to W2K8, and are wondering if it makes sense to spend the extra money on the Enterprise version or just stick with standard. We run a small data center (8 servers) with manual failover and basic script based mirroring. We will have 3 web servers and 2 database servers. There is no current need for instant failover between servers, and I don't anticipate our company growing beyond ~200 employees within the next 10 years (we're at 50 now).
Beyond Failover clustering, what advantages would Enterprise bring us over Standard?
