and virtual machines (VMs).
The VM-aware storage vendor released Tintri OS 3.2, which gives customers the ability to designate minimum and maximum IOPS to specific VMs so performance levels can be balanced to favor mission-critical systems.
The new Tintri SynchVM allows users to navigate back and forth between snapshots without losing older snapshots or performance history. The Tintri Global Center 2.0 management portal offers the ability to do deeper health monitoring and apply group policies across 32 physical hosts and more than 100,000 VMs.
"There is a lot of meat to this launch, a lot of interesting and unique things to it especially with the quality of service (QoS) capabilities," said Scott Sinclair, storage analyst at Enterprise Strategy Group. "Tintri says you can put a minimum guarantee on this application so it always gets a certain level of IOPS. That's the idea because IT guys care more about having certain applications meet [service level agreements] SLAs."
Tintri's QoS levels can be rebalanced to favor mission-critical databases and applications, ensuring they always have their fair share of the needed resources and they are guaranteed a certain number of IOPS even while contending with noisy neighbor VM issues.
Previously, Tintri's QoS levels ensured all VMs had their "fair share of the performance and fair share of the pain" when resources were rebalanced among VMs, according to Tintri senior director of product marketing Chuck Dubuque.
"This release now gives you a VM policy that breaks that fair share," he said. "A customer can say 'I have a SQL Server and I don't want it starved for resources.' The rest of the VMs now get their share of whatever resources are left over."
The top-of-the-line Tintri VMstore T880 array can handle up to 3,500 VMs and about 140,000 IOPS, Dubuque said.
Dubuque described Tintri SynchVM as "snapshots on steroids." The software, which works at the VM level rather than the volume or LUN level, now offers the ability to freely move back and forth among snapshot versions without losing the most recent snapshot or the history tied to the snapshots. Most snapshot software comes with the tradeoff that you lose the most recent snapshots the father back you go among versions.
"Each VM in a Tintri system can have up to 120 snapshots," Dubuque said "You can go back two weeks and forward three days without losing snapshots, without re-provisioning VMs and losing the performance history of the VMs."
The latest Tintri Global Center now has the ability to go beyond monitoring VM stores for health checks. It can set management tasks like naming conventions of VMs and apply policies across server groups. It can also set snapshot and replication polices. Customers can manage dynamic collections of VMs based on group definitions and policies. Groups can span VMstores, hypervisor types and geographies.
"Those policies follow the systems even when they move from one VM to another," Dubuque said.
The Tintri OS 3.2 will be available in May to all Tintri VMstore customers. Tintri SynchVM will be sold as separately licensed software for Tintri VMstore. The Tintri Global Center 2.0 is free for Global Center customers and requires separate license for other Tintri VMstore owners.
