The flash-optimized architecture behind the performance

HP 3PAR StoreServ Storage removes the bottlenecks that prevent legacy storage from taking full advantage of flash-based media. This is the driving force that allows the HP 3PAR StoreServ 20000 all-flash array to deliver 5X accelerated performance over storage that uses hard disk drives (HDDs) while delivering extremely low latency. This flash-optimized architecture relies on several new and unique HP 3PAR StoreServ innovations:

  • Unique, clustered, Mesh-Active architecture (figure 2): Up to eight controllers form a Mesh-Active cluster based on a unique system of controller node interconnects. Unlike traditional “Active-Active” architectures, this clustered design delivers robust, load-balanced performance, and greater headroom for cost-effective scalability that overcomes the tradeoffs typically associated with modular and monolithic storage.
  • HP 3PAR Gen5 Thin Express ASIC: Supports mixed workloads and enables thin technologies including inline deduplication with high performance levels to alleviate legacy storage performance concerns. The Thin Express ASIC supports mixed workloads with extremely high performance levels so that transaction- and throughput-intensive workloads run on the same storage resources without contention, enabling consolidation without compromise.
  • Adaptive read and write technology: Matches host I/O size reads and writes to flash media at a granular level to avoid unnecessary data reads and writes to reduce latency, enhance backend performance, and extend flash media lifespan to lower the total cost of ownership (TCO) for storage.
  • Autonomic cache offload: Reduces cache bottlenecks by automatically changing the frequency at which data is offloaded from cache to flash media based on utilization rate. This helps achieve consistently high performance levels as you scale up the workload to millions of IOPS.
  • Multi-tenant I/O processing: Enables performance improvement for mixed workloads or virtual desktop infrastructure (VDI) deployments by breaking large I/O into smaller chunks so that small read requests don’t get held up behind larger I/O requests, which helps ensure reduced latency.

HP 3PAR StoreServ 20000 Storage allows you to consolidate applications onto a single, high-performance system, giving your business the flexibility to meet changing business needs, on demand.

Get more out of your virtualization deployment

HP 3PAR StoreServ Storage is built to deliver performance that exceeds even the most stringent application demands along with transformative levels of simplicity, agility, and efficiency. Integration with Microsoft® System Center and VMware® vCenter, gives you enhanced visibility into storage resources and precise insight into how VMs are mapped to datastores and system volumes. Support for VMware Virtual Volumes (vVols) enables granular VM-level storage control, disaster recovery, and QoS in environments with VMware vSphere 6.

Integration with VMware vSphere API for Array Integration (VAAI), VMware vStorage APIs for Storage Awareness (VASA), Microsoft Offload Data Transfer (ODX), and thin provisioning enable HP 3PAR StoreServ Storage to improve virtual infrastructure performance, efficiency, and scalability. Low latency levels allow you to get more out of your VMware deployment, where extensive use of virtual memory pages to disk can limit VM consolidation on physical servers when paired with legacy storage. By contrast, deploying HP 3PAR StoreServ Storage enables you to double VM density on your physical servers—guaranteed.

If you are looking for virtually instant application-consistent backups for your VMware environment, look no further than rapid and granular backup and recovery with HP StoreOnce Backup. With HP StoreOnce Recovery Manager Central, you get fast, efficient, flat backup from HP 3PAR StoreServ Storage to HP StoreOnce Backup. This solution transforms traditional approaches to backup and recovery, giving you application-aware, storage-integrated data protection that bypasses traditional backup server-based processes.

Make your databases more efficient, without tradeoffs

Database performance and availability are so critical that many organizations apply generous capacity and management resources to maintain needed service levels. HP 3PAR StoreServ 20000 Storage removes these inefficiencies, helping eliminate tradeoffs between capacity utilization, efficiency, and performance. For example, with HP 3PAR Thin Persistence Software and Oracle ASM Storage Reclamation Utility (ASRU), your Oracle databases stay thin by autonomically reclaiming stranded database capacity. And HP offers the cost-effective Oracle- and SQL-aware snapshot technologies, HP 3PAR Recovery Manager for Oracle and HP 3PAR Recovery Manager for SQL. Low latency levels meet the requirements of response-time sensitive applications such as Oracle database and Microsoft Exchange.

Given the importance of Microsoft Exchange for mission-critical email communications, many organizations devote significant amounts of storage capacity and management resources to this essential application. HP 3PAR StoreServ 20000 Storage enables you to support a large number of mailboxes with a larger size limit while reducing cost per mailbox from dollars to cents. In addition, with HP 3PAR Recovery Manager for Exchange, you can recover email messages quickly, affordably, and from multiple points in time.

Elastic resource pool

Resilient—so you can consolidate with confidence

With a modern architecture that provides true convergence of block, file, and object access while helping eliminate single points of failure, HP 3PAR StoreServ Storage delivers Tier-1 resilience paired with secure administrative segregation of users, hosts, and application data. A unique set of data protection and security products power HP 3PAR StoreServ 20000 Storage in delivering high availability and resilience for multi-tenant cloud and ITaaS environments. Serve multiple user groups and applications from a single storage system with complete confidence that access to your data will not be compromised or interrupted. Ensure data protection at the array level, across the data center, and with a robust backup and recovery strategy.

Persistent technologies meet virtual datacenter demands

On HP 3PAR StoreServ 20000 Storage, Tier-1 resiliency is supported by persistent technologies unique to the platform:

  • Persistent Cache: The use of Persistent Cache preserves service levels so they are not impacted by unplanned component failures—a key requirement for the virtual data center.
  • Persistent Ports: A software feature allows non-disruptive upgrades to HP 3PAR StoreServ 20000 Storage systems, Persistent Ports means you don’t have to relying on multi-pathing software or failover initiation. This feature also automatically fails over a front-end controller node port that experiences physical connection loss due to a cable or switch failure in order to preserve service levels.
  • Persistent Checksum: Ensures end-to-end data integrity, protecting against silent corruption from the host to the storage array.
  • Peer Persistence: Federate storage across data centers, regardless of physical boundary constraints. Automated failover and failback between two sites or data centers is transparent to hosts, which keeps your VMware deployments seamlessly running even in the event of a disaster.

Secure multi-tenancy and data encryption support massive consolidation

Security concerns should not stand in your way when it comes to infrastructure consolidation. For this reason, HP 3PAR StoreServ 20000 Storage supports the security features you need, such as:

  • Virtual Domains: Unlike the use of multiple storage systems or traditional array partitioning schemes that rely on the physical segregation of resources, HP 3PAR Virtual Domains uses a policy-based, logical implementation that preserves the benefits of distributing and sharing each application workload across all system resources. Virtual Domains is ideal for those who understand the benefits of consolidation but must enable secure, independent storage services to multiple administrators, applications, departments, and customers.
  • Data-at-Rest Encryption: For environments that requires protection from unauthorized data access, encryption protects your data from both internal and external security breaches. HP 3PAR StoreServ 20000 Storage is fully FIPS 140–2 compliant, supports local and enterprise key managers that are FIPS certified and KMIP-compliant, and is available with encrypted FIPS 140–2 validated drives. These drives protect against unauthorized access, even if a drive is stolen, fails, or has to be retired.
  • Virtual Lock: HP 3PAR Virtual Lock Software enables organizations to securely lock down storage volumes, allowing read access but preventing accidental or intentional deletion. When used in conjunction with reservationless, nonduplicative snapshots, Virtual Lock delivers an efficient approach to governance and legal discovery.

Deliver uncompromising QoS for your most demanding workloads

Achieve higher service levels for more users and applications with less infrastructure. When combined with Tier-1 resiliency, the multi-controller scalability and extreme flexibility built into HP 3PAR StoreServ Storage makes deploying and maintaining separate storage silos to deliver different QoS levels obsolete.

High and predictable levels of service for all workload types are assured through the massively parallel and fine-grained striping of data across all internal resources (disks, ports, loops, cache, processors, and more). With this massive and fine-grained approach, as use of the system grows—or in the event of a component failure—service conditions remain high and predictable.

With HP 3PAR Priority Optimization Software, you can reduce contention by limiting maximum performance or setting a minimum goal for IOPS and bandwidth for a specific application, tenant, or workload. It provides high-priority applications with all the resources they need to meet service levels. It enables certainty and predictability for all applications and tenants.

Unlike application-centric approaches to storage, one-click autonomic rebalancing on HP 3PAR StoreServ Storage enables you to help optimize QoS levels without service disruption, pre-planning, or the need to purchase separate arrays to support different service levels.

Futureproof - to support on-demand computing

Data center transformation to address on demand computing in an investment. Protect your investment and maximize its effectiveness both today and into the future with a storage solution that not only aids you with today’s data center refresh, but also ensures that your storage assets and infrastructure are always optimized for your workloads.

Refreshing your storage technology is effortless

With HP 3PAR StoreServ Storage, you can refresh technology effortlessly by streamlining the movement of data from older systems and non-disruptively update storage without application impact. If you are looking to consolidate your HDS arrays, EMC Symmetrix VMAX, CLARiiON CX4, or VNX arrays, HP 3PAR Online Import Software make it easy for you.

Every HP 3PAR StoreServ Storage system comes with this software at no additional charge for 180 days—giving you painless, non-disruptive migration. And if you are currently an HP EVA Storage customer, you can use HP 3PAR Online Migration to import data from your EVA system onto your new HP 3PAR StoreServ array, providing you with a simple upgrade path.

Boost flash performance by 35 percent and reduce latency by 2.5X with 16 Gbps Fibre Channel

When replacing traditional HDD storage with hybrid or all-flash arrays to serve high performance workloads, it is critical to consider the role of your storage network and ensure that it isn’t acting as a bottleneck. For example, a typical OLTP workload can saturate 8 Gbps host Fibre Channel (FC) bandwidth without fully utilizing all of your compute or storage resources. To ensure you receive the anticipated returns on your flash investments, you may need to consider increasing your storage networking performance.
