Nexenta HA Case Studies

Wirehive
Wirehive opted for the NexentaStor High Availability (HA) Cluster with 70TB on a mixture of disk formats including HGST SSDs, Zeus RAM, and RAID using hardware from Supermicro. The HA option provides significant resilience and redundancy capabilities. Active failover capabilities for NexentaStor servers eliminate a NexentaStor server as a single point of failure. HA Cluster manages and controls the shared storage.

“I don’t have to worry about our storage,” he added. “The systems are fully High Availability (HA) – there isn’t a single point of failure. I know performance will be good. But, just in case, I have alerts to inform me if there is a performance issue. I don’t have to worry anymore. Nexenta gave me peace of mind.”

High availability (HA) was one of the key differentiators in SMHS’s decision to select the Nexenta solution. While some competitors can allow HA add-ons, Nexenta provides the plug-in and actively supports it.

“The first thing we noticed when we tested
 the system was that it was built on ZFS which is incredibly powerful and has features built in that are hard to find anywhere else. NexentaStor is also very flexible and we can use it for a powerful high availability (HA) Cluster as well as a high-powered solution for ultimate speed that underpins
the systems at the high performance
computing department.”

High Availability: “Having two controllers with NexentaStor HA is Nexenta’s main differentiator vs. commodity ZFS in my opinion,” said Soltesz. “High availability combined with ZFS is the primary reason we are so pleased with our implementation.”

It was through the HAC plugin that the company’s scalability issues were resolved, as data can run via a single head while the second head is upgraded.

‘To keep our IT-system flexible enough to react on the quickly changing energy market, we were looking for a new storage system that offered high performance, flexibility and high availability. We already had experience with Software Defined Storage but finally found the right solution with Nexenta’s approach.’

Statigest
The clustering capability in NexentaStor has been a significant benefit to Statigest by delivering enhanced stability with recovery from failover taking less than one minute

EnergieSudwest
The architecture, which is designed for high availability, consists of two redundant small computing centers several hundred metres apart and in different fire zones – what is known as a HA-cluster. This IT infrastructure can not only withstand the failure of any component but also is without any downtime; if one of the two computing centers suffers a major failure the system responds with a fully automatic and transparent failover to the other center.

University of Sussex
Both are clustered with tiered storage using SAS hard drives and SSDs with 110TB of capacity each. The University of Sussex are also planning an expansion of their Nexenta solution to include another 200TB for HA (High Availability) to support their growing research data warehouse.

The entire storage system with six clusters now holds over 1 Petabyte in storage. This all software defined setup proved to be a real winner as latency on all clusters was even lower than before with the more expensive Infiniband solution.

Simply Mail Solutions
The company now can rest easy knowing that it has a fully secure, redundant, two-of-everything back-up system in place.

City Clinic
Using the HA licensed feature, City Clinics established two clusters in its Bulgarian data centre and another in the Strasbourg facility to provide back up, disaster recovery, resilience and reliability. The HA licensed feature makes a NexentaStor implementation highly available and provides automatic or manual recovery in the event of disaster. This is essential for City Clinic because losing data access would be disastrous when hospitals need access to their data all of the time, 24 hours a day, 7 days a week.

The HA licensed feature makes a NexentaStor implementation highly available while recovery in the event of disaster can be automatic or manual. A user-friendly graphical user interface (GUI) makes it easier for non-IT personnel to activate recovery.

Vos Logistics
high availability, a significant requirement for Vos Logistics
Recovery time from failure has improved from five minutes under the previous system to less than 30 seconds

North Devon Homes
The system’s lack of resiliency was thrown into sharp relief by an outage that lasted a day and a half, highlighting the need for high availability and redundancy when it became apparent certain parts of the business could not continue without access to data
————————
Scalepoint
NexentaStor also features an additional high availability plug-in that provides data availability. Recovery, in the event of disaster, can be automatic or manual. A user-friendly graphical user interface (GUI) makes it easier for non-IT personnel to activate recovery.

Space2U
While searching for a suitable high availability, fault tolerant system, Space2U with the support of Layer 8, a Nexenta Certified Channel Partner, evaluated several solutions from legacy providers, including EMC and Dell Compellent.
Eventually, they selected a dynamic storage platform, based on Supermicro and powered by NexentaStor, a leading software-defined storage provider.

LexisNexis
When using the HA Cluster licensed feature, neither NexentaStor appliance is designated as the primary or secondary system, so two NexentaStor instances can be configured as an active/active pair. Storage is jointly managed via the HA Cluster, configured as shared storage. System failures can be detected and shared volumes transferred to the other server in the cluster pair. The licensed feature provides high availability for shared storage accessible from both appliances.

Virtion
High availability, unlimited snapshots, and ease of management made NexentaStor particularly suited to virtion’s managed hosting services model.

“We were feeling the heat, both literally and figuratively, from our legacy storage system. Failures from overheating and age were causing downtime for staff and delays in customer response time. Nexenta was able to solve all these issues, easily and within budget.”

Korea Telecom
In particular, the company needed an OpenStorage solution that could run on standard hardware and provide extended functionality, such as deduplication, compression, self-healing, synchronous and asynchronous replication, and HA cluster availability.
In addition, the NexentaStor HA Cluster plug-in provides global access, in a range of time zones, with consistent data access.

Delano Regional Medical Center
A major component of DRMC’s solution involved NexentaStor’s HA Cluster licensed feature. This licensed feature enables two NexentaStor instances to be configured as an active / active pair, which provided DRMC with high availability for shared storage, accessible from both appliances.

TWM
High Availability (HA) Plug-in: The HA Plug-in enabled the NexentaStor implementation to be highly available. Recovery, in the event of a disaster, could either be automatic or manual. With the user-friendly Graphical User Interface (GUI), recovery now could be executed by non-IT personnel.

INgrooves
After the success of the POC, INgrooves deployed two additional zStax HA clusters, bringing their total to more than 600 TB of usable storage space.

Landair
The Nexenta HA cluster licensed feature enabled Landair’s IT management team to maintain around-the-clock transportation services while lowering their storage acquisition cost (compared with legacy HA technologies.)
Landair’s Open Storage HA cluster solution came in at one-quarter of the cost of a legacy closed-platform solution.
