Dimension Data CloudControl Storage upgrade programme: Change to Standard/High Performance/Economy Disk Speeds in AP3 (Singapore) Effective November 1st
Change has been successfully implemented and testing confirms the change is working as designed.
We will leave this notification up through 02:00 UTC Friday simply to make users aware of the change but the maintenance event is complete.

Dear Client
As part of our ongoing improvement initiatives, we will be kicking off our storage upgrade programme to give a better, predictable and consistent experience when it comes to cloud storage. We have invested new industry-leading hardware to meet the above and to ensure sustainable performance as we continue to grow.
To this end, on Thursday November 1st, the following disk speeds (tiers): Economy, Standard and High Performance, in AP3 (Singapore) will be transitioned to our new “burstable” storage environment.
In AP3, the change will be implemented in 2 stages:
STAGE 1: Application of storage changes to newly provisioned disks; during expansion of current disks and when disk speed changes are made. This change will be applied on November 1, 2018.
STAGE 2: Application of the storage changes to the existing disks. This change is now planned to be applied in mid-November.
There is no downtime or maintenance associated with this change, hence the enablement will occur outside of the software upgrade window on November 1, 2018 at approximately 10:00 PM Singapore Time (14:00 UTC)
Here is a summary of the impacts that should be expected with the first stage:
For all newly deployed servers, new disks added to existing servers, and changes to existing disks such as disk expansion or a change in disk speed:
1. Disks will be allowed to burst up to the following IOPS limits:
ECONOMY: Greater of 100 IOPS or 0.5 IOPS/GB based on the size of the disk STANDARD: Greater of 500 IOPS or 3 IOPS/GB based on the size of the disk HIGH PERFORMANCE: Greater of 800 IOPS or 6 IOPS/GB based on the size of the disk
Example: A 100 GB Disk using Standard Disk Speed will be assigned a 500 IOPS maximum. A 180 GB Disk using Standard Disk Speed will be assigned 540 IOPS maximum (180 GB x 3 IOPS/GB).
2. Disks will be allowed to burst up to a Throughput limit equal to the IOPS maximum x 16 KB. This limit applies in addition to the above IOPS limit.
Example: A 100 GB Disk using Standard Disk Speed will be assigned an 8,000 KB/second Throughput maximum (500 IOPS x 16 GB). A 180 GB Disk using Standard Disk Speed will be assigned an 8,640 KB/second Throughput maximum (540 IOPS x 16 KB)
