Consider the following recommendations for Dell APEX Protection Storage for Azure (DDVE):
- DDVE capacity can be dynamically expanded by adding more data disks to the instance. Increments of 1 TB are recommended. When the maximum capacity that the instance supports is reached, you must upgrade the VM to a larger size before adding more storage to the system.
- The local block storage is used for caching metadata. Based on different workloads, the needed metadata size varies. It is recommended that you configure the metadata storage size as 10% of total capacity, which is enough for most workloads. For workloads with a higher deduplication ratio, more metadata is needed.
- When you use DDVE on Hot Blob storage, ensure that your Hot Blob storage account and DDVE instance are in the same region. Configuring the VM and storage account in different regions can result in lower performance and higher costs.
- Azure infrastructure throttles each storage account, and each storage account has its own IOPS and throughput limits. For best performance, create a separate storage account for each DDVE.
- To prevent brute force attacks on the DDVE, do not use a public IP address to configure your system.
