Skytap service limits

Your Skytap account has limits for VMs and environments for each region, as well as network and other limits for the overall account. This page provides details about those limits, both account-wide and for all Skytap regions.

If you’re a primary administrator and you need specific capabilities that exceed these limits, contact support@skytap.com. Include your name, email address, and the name of your organization. If you’re a standard user or administrator, work with your primary administrator to request an increase.

IOPS for x86 VMs

IOPS for x86 VMs scale with the amount of RAM allocated to the VM, depending on region.

US-West

RAM-based IOPS scaling for x86 VMs in US-West.

VM RAM IOPS
1 GiB 250
2 GiB 325
3 GiB 400
4 GiB 475
5 GiB 550
6 GiB 625
7 GiB 700
8 GiB 775

Many factors affect storage performance, including file size and the number of files acted upon. These values represent the maximum IOPS capabilities of a VM.

All other regions
