Purity for FlashArray Data Sheet

Purity delivers the industry’s most granular, comprehensive data reduction—and the industry’s best total efficiency, averaging 10:1—with savings that are typically twice as good as the competition. Unlike other vendors’ products, our data reduction and thin provisioning are built-in, always-on, and require no tuning. It’s simple and predictable, even predictive. As a result, you’ll buy less storage now, and less in the future.

The following capabilities are what put Purity as the industry leader in data reduction:

• Always-on:The Purity Operating Environment is designed to support high-performance, always-on data reduction. All our performance benchmarks are taken with data reduction on.
• Global:Purity Reduce dedupe is inline and global unlike data-reduction solutions that operate within a volume or a pool, thereby partitioning the data and dramatically reducing dedupe savings.
• Five reduction technologies:纯洁的数据简化必要的近any application, already built-in, including pattern removal, deduplication, compression, deep reduction, and copy reduction.
• Variable addressing:With variable addressing, Purity finds duplicates that fixed-block implementations miss. Purity Reduce scans for duplicates at 512-byte granularity and auto-aligns with application data layouts without tuning at any layer. In addition, variable (byte-granular) compression avoids diluting your savings with waste propagated by fixed-bucket granular compression implementations.
• Compression algorithms:Purity employs multiple compression algorithms for optimal data reduction for different kinds of data.•Designed for mixed workloads: Purity Reduce delivers optimal data-reduction savings for mixed workloads without requiring trade-offs and/or tuning. That’s unmatched simplicity for the real world of your data. Purity employs multiple compression algorithms for optimal data reduction for different kinds of data.

Thin provisioning dynamically allocates capacity on demand for all volumes and workloads, optimizing utilization of the array. While many vendors use thin provisioning to boost data-reduction savings, thin provisioning is an over-provisioning strategy vs. a data-reduction technology. The Purity Reduce Ticker works differently, calculating only the average data reduction savings from deduplication and compression, which is separate from Pure’s total efficiency wherethin-provisioningis included. Granularity is at the 512-byte level just like all Purity services, meaning that Purity thin provisioning delivers even more efficiency than the competition.

Purity Optimize with Quality of Service (QoS) and DirectMemory Cache features, effortlessly delivers consistent application service level agreements and improved database, analytics and reporting performance. Always-on QoS provides IOP and bandwidth limits to ensure applications get the resources they need and you can consolidate radically diverse applications without fear of I/O contention. DirectMemory Cache software automatically stores hot data read from flash media in the array to onboard DirectMemory Modules with Intel Optane storage-class memory. Once the modules are non-disruptively added to a new or existing FlashArray//X70R2 or //X90R2, DirectMemory Cache begins working, without the hassle of configurations or tuning. You can expect the array to start providing latency improvements, along with additional throughput, for FlashArray workloads.

Purity Protect combines Purity ActiveCluster with space-saving snapshots, replication, and protection policies into an end-to-enddata protection and recovery solutionthat protects data against loss locally and globally (to heterogeneous NFS targets). AllPurity Protectservices are fully integrated in FlashArray and leverage native data-reduction capabilities.

Simplify business continuity withPurity ActiveCluster, Pure’s ultra-simple solution for running applications active-active between two data centers. The innovative design of ActiveCluster, including the cloud-based Pure1® Cloud Mediator, enables all data-center applications to use metro-area cluster-ing. ActiveCluster also delivers asynchronous replication to a third site globally. Purity async replication is active-active, meaning that a target array makes intelligent and resilient use of async replication links from both source arrays. ActiveCluster does not require re-baselining after the loss and recovery of a replication link. Best of all, ActiveCluster takes just minutes to set up, requires no third site, and is included with theEvergreen subscription.

Asynchronous and snapshot replications are the powerful combination behind ActiveCluster. With this approach, you can achieve low recovery point objective with regular delta updates and enable RTO zero via instant recovery from point-in-time snapshots. Benefits include:

• Data-reduction optimization, meaning always thin, deduped, and com-pressed. With it, you can eliminate lost performance, ballooning data, and added complexity.
• Instant recovery enables RTO zero with no data copying required so you can get back online faster.
• Multisite replication with one:many, many:one, or many:many replication delivers flexibility that you can use for data sharing, centralized backup, or disaster recovery.

Data backup is no longer simply about storing data. It’s about flexible protection, fast restores, and—above all—making your valuable data available for other uses, such as test/dev and analytics. Legacy, complex disk-to-disk-to-tape backup architectures can no longer keep pace with the advanced and constant flow of data that businesses must protect—and exploit. Purity is a key element in flash-to-flash-to-cloud. It’s designed for the scale and use cases of a modern backup strategy, providing more flexible backup and recovery options, faster restores to meet aggressive recovery-time objectives (RTOs), and simpler, more efficient operations while taking advantage of cloud economics. Consolidate workloads on FlashArray and secure them with a robust flash-to-flash-to-cloud backup and recovery strategy.

Pure portable snapshots provide simple, built-in, local and cloud protection for Pure FlashArray. Together, Purity Snapshots, Snap-to-FlashBlade, Snap-to-NFS, and CloudSnap enable free movement of space-efficient copies either between FlashArrays, to FlashBlade, to third-party NFS storage, or to the cloud, respectively. Unlike other cloud backup solutions,Pure portable snapshotsare cost-efficient, because they encapsulate metadata, which means they’re incremental, space-efficient, and self-describing.

FlashArray meets the highest security standards with FIPS 140-2 validated always-on encryption, NIAP/Common Criteria Certification, and rapid data locking. It’s well-equipped to assist with compliance on new data regulations such as GDPR. EncryptReduce, introduced in Purity 5.3, allows for full in-flight encryption of data from a host, over the network, to a Pure FlashArray. This ensures greater security and all the data reduction benefits FlashArray has always offered.

Purity continuouslyencrypts all datawithin FlashArray via FIPS 140-2 validated AES-256 encryption, meeting the U.S. government’s highest security standard for data-at-rest encryption. Encryption is built-in, always-on, always in-line, and costs nothing: there’s no impact on performance, administrative overhead, key management—and no additional fee.

Purity EncryptReduce, in conjunction with our partner Thales eSecurity, allows for full in-flight data encryption from a host, over the network, to a Pure Storage FlashArray.

This achievement provides the following:

• Allows for in-flight encryption over the wire
• Allows FlashArray to perform its standard data reduction
• Provides physical security through Key Management Interoperability Protocol (KMIP)

FlashArray’s features demonstrate its stringent standards fordata system security. Rapid data locking (RDL) offers smart card-based instant locking of an array. Similarly, KMIP support enhances software-generated secrets used to regenerate an array’s flash module access keys.

You can instantly disable an array and crypto-lock its data, greatly reducing risk of loss, capture, or compromise. Secure administration includes multiple account types, directory-based authentication, and secure management connectivity to enable secure administration.

Every organization that collects and/or processes the data of subjects in the European Union is subject to and must comply with the General Data Protection Regulation (GDPR). Penalties for non-compliance are significant, but a combina-tion of data policies and technology considerations—such as encryption and data reduction—can help you achieve GDPR compliance cost-effectively.
