NetApp EF540 Flash Array Software

Streamlined and optimised for low-latency performance, NetApp SANtricity software powers the EF540 flash array.

Leveraging 20 years of experience supporting high-performance workloads and business-critical database environments, NetApp® SANtricity® software is designed to combine sustainable, low-latency performance with enterprise-class availability and protection. Its streamlined firmware is well suited for the extreme demands of latency-sensitive workloads. And SANtricity software helps keep I/O flowing with automated path failover, online administration, advanced data protection, proactive monitoring and repair, non-disruptive upgrades and extensive diagnostic capabilities.

SANtricity software:

  • Leverages its streamlined firmware to deliver consistent, sustainable, low-latency performance
  • Provides extensive tuning capabilities to maximise performance for wide-ranging workloads
  • Monitors SSD wear life and will issue an alert if defined thresholds are reached
  • Delivers best-in-class reliability with state-of-the-art data protection, advanced monitoring, proactive repair and AutoSupport™ capabilities
  • Features extended data protection via FC- and IP-based remote mirroring, Dynamic Disk Pools, enhanced Snapshot™ copies, data integrity assurance and extensive diagnostic capabilities

The following table describes standard SANtricity software features.

FunctionalityProduct/FeatureDescription
ManagementStorage administrationSANtricity Storage Manager software provides management functionality and a graphical representation of EF-Series and E-Series storage systems, with an easy-to-use interface for customisation and ongoing operations.
Enterprise Management WindowThe EMW gives a comprehensive view of all EF-Series and E-Series storage systems in the management domain. From the EMW, administrators can add and remove hosts and storage systems, monitor the health of the storage and report its high-level status, configure alert notifications, run scripts to perform batch management tasks and launch the applicable Array Management Window for a selected storage system to perform detailed configuration and management operations.
Array Management WindowEach individual EF-Series flash array is managed through a dedicated Array Management Window. The AMW is used to configure and reconfigure volumes (including attributes such as size, name, modification priority, cache settings and segment size), define hosts and host groups, grant host or host group access to sets of volumes (called storage partitions), monitor the health of system components, view the Event Log and storage profile, assign hot spares and monitor storage system performance.
High AvailabilityI/O Path ProtectionI/O path protection offers load balancing and multi-path capabilities for path fail-over in the event of a connection, HBA or server failure.
Online administrationAll management tasks can be performed while the storage remains online, with complete read/write data access. This allows storage administrators to make configuration changes, conduct maintenance (including firmware upgrades) or expand the storage capacity without disrupting the I/O from its attached hosts.
Data ProtectionRAID levels 0, 1, 3, 5, 6 and 10With support for multiple RAID levels, SANtricity software offers the flexibility to address varying performance and capacity requirements, and service levels.
Dynamic Disk PoolsDDP allows storage administrators to improve data protection and maintain predictable performance under all conditions. DDP evenly distributes data, protection information, and spare capacity across the flash array's entire pool of drives. Its next-generation technology minimises the performance impact of a drive failureand can return the system to optimal condition up to eight times faster than traditional RAID. With shorter rebuild times and patented prioritise reconstruction technology, DDP significantly reduces exposure to multiple disk failures, offering a level of data protection that simply can't be achieved with traditional RAID.
Proactive Drive Health MonitoringProactive Drive Health Monitoring examines every completed drive I/O and tracks the rate of error and exception conditions returned by the drives, as well as drive performance degradation that is often associated with unreported internal drive issues. Using predictive failure analysis technology, when any error rate or degraded performance threshold is exceeded – indicating that a drive is showing signs of impending failure – SANtricity software issues a critical alert message and takes corrective action necessary to protect the data.
Wear Life MonitoringSANtricity software proactively tracks SSD wear life and issues a critical alert message when defined thresholds are reached.
Data ReplicationLogical Copy – SANtricity Snapshot™ softwareSnapshot software creates a point-in-time image, or logical copy, of a storage volume, enabling secondary servers to access a suspended version of production data for a variety of applications, including backup, application testing or development, information analysis and data mining.
Clone – Volume CopyVolume Copy creates a complete physical copy (clone) of a volume in a storage system. The clone volume is a unique entity that can be assigned to any host and used by applications that require a full point-in-time copy of production data (such as backup, application testing or development, information analysis or data mining) without affecting the performance of the production volume.
Disaster Recovery – Remote Volume MirroringSynchronous and asynchronous data replication software delivers simple, efficient and flexible remote disaster recovery for business-critical applications.
Problem ResolutionAdvanced DiagnosticsExtensive capturing and monitoring of diagnostic data provide comprehensive fault isolation and simplify analysis of unanticipated events.
Recovery GuruThe Recovery Guru provides troubleshooting assistance and determines the appropriate procedure to use for recovery, so that operations can be restored as quickly as possible. The Recovery Guru displays detailed information about a particular problem and lists the recovery steps to restore operations.
