In the last 12 months, many businesses have transformed the way they operate to meet the new demands of the market conditions, and we have seen an increase of public cloud services being used and a ramp-up of services to enable home workers.
This year the focus has shifted from mobilising interim changes to customers starting to review and adopt permanent architecture changes to being more agile, scalable, and resilient. Customers are also looking for solutions that are consumption-based through an OpEx model.
A common challenge that we are also seeing is that migration to the public cloud isn’t straight forward. Challenges such as legacy applications that were developed to be compatible with traditional storage lead to considerations to re-architecting applications to be cloud-native. This often results in services remaining on traditional infrastructure.
We believe that Hybrid Cloud is the future, this is where you can use the best of both worlds from building an on-premises Private Cloud to utilising native Public Cloud Services that in combination meets the demands of being agile, scalable, resilient and are offered “as a service” on an OpEx Model.
DR and Backup solutions could be a good use-case for you to implement a Hybrid Cloud solution. With this in mind, let’s discuss three HPE Cloud services:
- HPE Cloud Volumes Block
- HPE Cloud Volumes Backup
- HPE Cloud Bank Storage
HPE Cloud Volumes Block
HPE Cloud Volumes is an enterprise grade multi-cloud storage solution built on proven storage hardware with high uptime and availability, high performance and secure 256-bit AES encryption, replication, snapshot and cloning features. The Cloud Volume Block service is a consumption-based service that allows customers to build a more successful DR plan.
An example below shows from an on-premises HPE Nimble Storage array, you can replicate a local volume to the HPE Cloud Volume Block service. If a disaster was to occur at your datacentre, you have the choice to clone the replica volume and present this to a public cloud service such as AWS, Azure or GCP.
Note: Unlike most public cloud services, there are no egress charges from the HPE Cloud Volume services.
HPE Cloud Volumes Backup
HPE Cloud Volumes Backup allows transferring data from private and public cloud solutions to be stored in this service. The solution uses the StoreOnce API’s and therefore allows StoreOnce appliances to replicate catalyst stores to the HPE Cloud Volume Backup service. In the event of a disaster on your primary site, you can recover the data either to HPE Cloud volumes block and present it to a public cloud service or recover the data back to an on-premises site.
As shown in the below diagram, HPE Cloud Volumes Backup can help you with your 3-2-1 Data protection strategy, which is to have 3 copies of data in 2 different media types and where 1 copy is offsite.
HPE Cloud Volume Backup is compatible with HPE solutions (StoreOnce & RMC) or Backup solutions (Micro Focus, Veritas, Veeam and CommVault). The Backup strategy below shows that from the primary storage, a backup can be taken to either a StoreOnce Appliance or to one of the Backup solutions. Hence, you have a “Secondary Copy” onsite that could provide fast recovery, and then a “Tertiary Copy” can be sent offsite to the HPE Cloud Volume Backup service, which could replace Offsite tape backups and rotation.
HPE Cloud Bank Storage
HPE Cloud Bank storage is a feature that enables StoreOnce customers to leverage cost-effective storage (on-prem or public cloud) for long-term retention of data. Unlike HPE Cloud Volumes which is a complete stand-alone service offering i.e service provides the back-end infrastructure and you consume the service.
HPE Cloud Bank Storage is a feature that requires a HPE StoreOnce Appliance to be enabled and configured. This allows the replication of the local data in the StoreOnce Catalyst store to be deduplicated and transferred to Cloud Bank Storage.
The Cloud Bank Storage needs to be configured and supported by an object storage solution such as HPE Scality which can be architected from hardware installed on-premises or a public cloud object storage service such as Azure Blog storage which can be designed and configured to use hot, cool or archive storage tiers.
Note: The public cloud object storage (i.e. Azure blob storage) can be detached from the HPE Cloud Bank store for archive purposes. If an onsite StoreOnce Appliance fails, another StoreOnce Appliance can be attached to recover the data.
The HPE services can provide coverage to complement your DR and Backup strategy whilst offering a service consumption-based billing.
Cloud Volume Block is Enterprise-grade, multi-cloud service for storing and managing data in public clouds. Maximum agility for hybrid or cloud native workflows, like DR, Hybrid CI/CD or Hybrid Reporting and Analytics.
Cloud Volume Backup is Secure and efficient for backup and recovering data from anywhere to anywhere. Restore to on-premises or Cloud Volumes block for DR or development.
Cloud Volume provides “the agility of the cloud, without the data egress costs, or lock-in”
Cloud Bank Storage is a simple and cost effective, tiered archive to the cloud. Store PiBs of data indefinitely at minimal costs.
As the diagram below shows you the summary of the costs versus the SLA / Time to Availability for the three services discussed here.
