Is this server good for running a large database?

Yes. 256GB of RAM and four SSDs in RAID 10 are well suited to databases that need memory caching and fast, redundant storage. The dual 14-core CPUs handle concurrent queries well.

How does RAID 10 affect usable storage?

RAID 10 mirrors and stripes the four 2TB drives, so usable capacity is about half the raw total. You gain faster reads and tolerance of a drive failure.

Can I run multiple virtual machines on it?

Yes. 28 cores and 256GB of RAM support a modest private cloud or several VMs. Plan RAM and disk per VM, since RAID 10 cuts usable SSD space.

Is the bandwidth enough for a busy website?

A 1Gbps port handles most sites and APIs comfortably. If your traffic is sustained near the cap, ask about upgrading the uplink before you commit.

What is included with the server?

The hardware as configured, the RAID 10 SSD array, the 16TB SATA drive, one dedicated IP and the network port. Operating system and control panel are your responsibility.

How does it compare with a cloud instance?

You get far more RAM and local SSD storage on dedicated hardware, without noisy neighbors. You give up elastic scaling, managed services and quick hardware changes.
