At first glance, Red Hat’s acquisition of clustered open-source storage player Gluster seems like a pure storage play, perhaps with a bit of open-source camaraderie mixed in. But before it was bought out, Gluster was positioning itself as a virtualization player, too.
Red Hat’s FAQ on the Gluster buy gives a nod to how the purchase fits into the company’s virtualization and cloud computing strategy, emphasizing the use of commodity hardware and scale-out capabilities.
We view Gluster to be a strong fit with Red Hat’s virtualization and cloud products and strategies by bringing to storage the capabilities that we bring to servers today. By implementing a single namespace, Gluster enables enterprises to combine large numbers of commodity storage and compute resources into a high-performance, virtualized and centrally managed pool. Both capacity and performance can scale independent of demand, from a few terabytes to multiple petabytes, using both on-premise commodity hardware and public cloud storage infrastructure. By combining commodity economics with a scale-out approach, customers can achieve better price and performance, in an easy-to-manage solution that can be configured for the most demanding workloads.
There’s also potentially an even more direct virtualization play here, based on Gluster’s history. The company came out of stealth in 2007 with GlusterFS, a scale-out file system for clustered NAS based on open-source code, and by late 2009 was offering support for running virtual machines (VMs) directly on its clustered NAS.
Customers who chose this option could use the cluster’s internal replication to provide high availability (HA) failover for VMs running on the cluster using a checkbox at the time of installation. From there, the file system automatically handled replication using an underlying object-based storage system.
As governing the data center infrastructure becomes the next frontier for virtualization players, this purchase could be seen as an answer to forthcoming vStorage APIs from VMware that aim to bring server and storage virtualization closer together, as well as to new storage virtualization products like Nutanix, which have the same broad goal.
