52: GreyBeards talk software defined storage with Kiran Sreenivasamurthy, VP Product Management, Maxta

This month we talk with an old friend from Storage Field Day 7 (videos), Kiran Sreenivasamurthy, VP of Product Management for Maxta. Maxta has a software defined storage solution which currently works on VMware vSphere, Red Hat Virtualization and KVM to supply shared, scale out storage and HCI solutions for enterprises across the world.

Maxta is similar to VMware’s vSAN software defined storage whose licenses can be transferred from one server to another, as you upgrade your data center over time. As software defined storage, Maxta runs on any standard Intel X86 hardware. Indeed, Maxta has one customer running two Super Micro servers and one Cisco server in the same cluster.

Maxta advantages

One item that makes Maxta unique is all of its storage properties are assignable at a VM granularity. That is,  replication, deduplication, compression and even blocksize can all be enabled/set at the VMDK-VM level.  This could be useful for environments supporting diverse applications, such as having a 64K block size for Microsoft Exchange and 4K block size for web servers.

Another advantage is their multi-hypervisor support. Maxta’s support for RH Virtualization, VMware and KVM offers the unique ability to migrate storage and even powered off VMs, from one hypervisor to another. Maxta’s file system is the same for both VMware and KVM clusters.

Maxta clusters

Their software must be licensed on all servers in a vSphere or KVM cluster with access to Maxta storage. The minimum Maxta cluster size is 3 nodes for 2-way replication and 5 nodes for 3-way replication.  Most Maxta systems run on 8 to 12 server node clusters. But Maxta has installations with 20 to 24 nodes in customer deployments.

Maxta supports SSD only as well as SSD-disk hybrid storage. And SSDs can be NVMe as well as SATA SSD storage. In hybrid configurations, Maxta SSDs are used as read and write back caches for disk storage.

Maxta supports compute only nodes, compute-storage nodes and witness only nodes (node with 1 storage device). In addition, besides heterogeneous server support, Maxta clusters can have nodes with different storage capacities. Maxta will optimize VM data placement to balance IO activity across heterogeneous nodes.

Maxta provides a vCenter plugin so VMware admins can manage and monitor their storage inside vSphere environment. Maxta also offers a Cloud Connect MX which is a cloud based system allowing for management of all your Maxta clusters through out an enterprise, wherever they reside.

Even HCI, through partners

For customers wanting an HCI solution, Maxta partners can supply pre-tested, HCI appliances or can configure Maxta software with servers at customer data centers. Maxta has done well OEMing their solution, and one significant success has been their OEM deal with Lenovo in China and East Asia, where they sell HCI appliances with Maxta software.

Maxta has also found success with managed service providers (that want to deploy the software on their own hardware), and SME & ROBO environments. Also Maxta seems to be doing very well in Latin America as well as previously mentioned China.
