Microsoft StorSimple solves this problem by keeping the active working set of data available on a storage appliance installed locally and by migrating the currently unneeded data to the Microsoft Azure Cloud in an encrypted form.
Microsoft offers two variations:
Microsoft StorSimple 8100 provides 15 TB of local disk space that can be expanded to 40 TP through compression and de-duplication. Any additional requirements are sourced in the Microsoft Azure Cloud. Hence, up to 200 TB can be stored on a Microsoft StorSimple 8100 – although it requires just two rack units in height.
Tucked away in a mere four rack units, the StorSimple 8600 model has a capacity of 40–100 TB in local storage and 500 TB overall capacity. The appliance is exclusively connected via 1/10 GbE Ethernet iSCSI and comes with fully redundant, internal components for maximum redundancy.
Now the extensive options provided by Mcrosoft Azure Cloud are available to enhance these basic features. And that’s where the product really gets interesting. All Microsoft StorSimple appliances are managed using the StorSimple Manager in Microsoft Azure. Put simply: You won’t get bogged down in any kind of complex local management toolset. What’s more, you can take a snapshot of the entire data set locally or in the cloud. The benefit here is that the volumes located on the local appliance can be duplicated for test purposes (e.g. with Azure VMs). If you like, it is just as easy to handle backups entirely in an Azure Backup Vault, making the in-house tape architecture obsolete in one fell swoop.
Users are also protected against complete loss of a datacenter location. This is because Azure StorSimple allows application of virtual scenario to access data kept on an Azure Blob Storage. The data set stored on Azure is then copied to the local surrogate appliance as soon as the company location is back online. It can even be copied to a different location as required. In figurative terms you could even call it the Dropbox principle, even if Microsoft is unlikely to be particularly delighted at the comparison.
