A little bit about Gigabyte (GB) and Gibibyte (GiB) in computer storage

I am going to write a little bit about this basic concept in storage: Gigabyte (GB) and Gibibyte (GiB). This is all because of the annoyance between standard and reality.

I can still remember 15 years ago, when I first got in touch with enterprise storage system, the first concept introduced is about the differences between physical disk labelled size and reported size in storage system. No need to calculate, even today, I can still clearly remember a 73GB SAS disk will report 66GB usable capacity in EMC CLARiiON, a large part of this difference is contributed by the difference between GB and GiB.

Deploy HPE StoreOnce VSA in Azure

HPE StoreOnce is a deduplication storage system providing efficient data compression and deduplication capability and suitable for data backup and long-term retention. HPE StoreOnce can be integrated with major backup vendors as the backup target storage.

In Azure, there is virtual edition of HPE StoreOnce in Azure Marketplace.  Deploying and initializing the HPE StoreOnce VSA is a very pleasant process with a straightforward outcome.

Since the HPE StoreOnce supports the data replication between appliances, the Azure based StoreOne VSA could be a good candidate of remote DR data copy by replicating the data from on-premise StoreOnce system.

It is noted that the VSA deployed in Azure will come with a trail license: “One time instant-on license for up to 90 days with a maximum 500TB capacity. No support provided by HPE.”

This post is to outline the deploying steps for quick reference.
