When the capacity of the associated DESS devices in a HyperMetro resource is insufficient, you can expand it.

Prerequisites

The associated DESS devices in the HyperMetro resource are available and both their available capacities do not reach 100 TB.

Precautions

For details about the DESS device capacity expansion rules associated with HyperMetro, see the following table.

Type	Description
Common I/O, common I/O (low latency)	The capacity of a DESS device can be expanded only when the device is in the Available state and the device capacity you have applied for does not reach the maximum capacity - 100 TB. The initial capacity of a DESS device is as follows: 10 TB: Capacity expansion can be performed once after capacity expansion to 20 TB. The capacity expansion specification is 20 TB. Other capacity: Only one capacity expansion is supported, and the capacity expansion specification is 20 TB.
High I/O, high I/O (low latency)	The capacity of a DESS device can be expanded only when the device is in the Available state and the device capacity you have applied for does not reach the maximum capacity - 100 TB. Only one capacity expansion is supported, and the capacity expansion specification is 20 TB.
Ultra-high I/O, ultra-high I/O (low latency)	The capacity of a DESS device can be expanded only when the device is in the Available state and the device capacity you have applied for does not reach the maximum capacity - 100 TB. The initial capacity of a DESS device is as follows: 10 TB: Capacity expansion can be performed multiple times after capacity expansion to 20 TB. The subsequent capacity expansion specifications are 20 TB, 40 TB, 60 TB, and 80 TB. Other capacity: Capacity expansion can be performed for multiple times. The capacity expansion specifications are 20 TB, 40 TB, 60 TB, and 80 TB.

NOTE:

If both associated DESS devices require larger capacities, you need to manually perform capacity expansion on them one by one.

Procedure

Click and select the wanted region.
Click and choose Dedicated Cloud > Dedicated Enterprise Storage to go to the DeC management console.

On the navigation pane on the left, choose Dedicated Enterprise Storage > HyperMetro to go to the HyperMetro resource list page.
Click next to the HyperMetro resource name to expand its details.
Click Expand on the row of the associated storage device. The Expand page is displayed.
Select the capacity to be added.

NOTE:

The post-expansion capacity of the DESS device can be 100 TB at the maximum.
Click Apply Now.
Confirm the order information and click Submit.

Follow-Up Procedure

After submitting an order, in the upper right corner on the DESS home page, choose Fees > My Orders and click Details to view the order details.

For details about the HyperMetro order status, see Table 1.

**Table 1** HyperMetro order status description
