1 W-VMBASE [abc-pa01]-VM Base(1CPU\1GB Ram) $6.00
A VPS needs at least one CPU and 1GB of RAM in order to function. Any VPS ordered will get deployed with 1 one CPU and 1GB memory at a minimum.
1 W-VMCPU [abc-pa01]-VM Virtual CPU(Additional) $4.00
This virtual private server has 2 CPUs total (The VMBASE mentioned above plus one additional CPU mentioned here).
7 W-VMRAM [abc-pa01]-VM RAM(1GB)(Additional) $14.00
7GB of RAM was added to this order on top of the 1GB included in the vm base. This brings the total amount of RAM up to 8GB total.
50 W-VMSPERF OS Drive Performance Tier Storage $5.50
Managed servers will have a set amount of storage allocated for the operating system disk. 50GB is the current default size. The amount of storage is then multiplied by $0.11 for Performance tier storage.
40 W-VMSUTIL User Drive Utility Tier Storage $1.60
The customer data/application drive (E:) was requested with a 40GB drive using Utility tier storage. This tier of storage is less expensive than the Performance tier storage that was selected for the operating system above. The price difference is due to the performance level of the storage type selected. The amount of storage is multiplied by $0.04 for utility tier storage.
1 W-STD IST Windows Standard Support 8-5M-F $153.00
Managed servers will either have a Standard (W-STD) or Extended support contract (W-EXT). Standard support covers monitoring and incident reporting Monday through Friday from 8AM to 5PM. Extended support (not selected) extends support to 24x7.
