The Smart Array Advantage

HPE's innovative design and integration work of the Smart Array family of products creates customer value that is unmatched in the industry. Use of Smart Array products across multiple applications results in a much lower Total Cost of Ownership (TCO) than any other server storage RAID product. The HPE Smart Array family brings an unparalleled return on investment through:

Data Compatibility among most current shipping Smart Array controllers allows simple and easy upgrades any time needs for higher performance, capacity, and availability increase. Even successive generations of Smart Array controllers understand the data format of other Smart Array Controllers.

Consistent Configuration and Management Tools. Most current shipping Smart Array products utilize a standard set of management and utility software. These tools minimize Total Cost of Ownership (TCO) by reducing training requirements and technical expertise necessary to install and maintain the HPE server storage.

SmartDrive Carrier form factor is for use across multiple Hewlett Packard Enterprise servers, Universal Hard Drive form factor is for disk enclosures and storage systems. With compatibility across many enterprise platforms, you are free to deploy and re-deploy these drives to quickly deliver increased storage capacity, migrate data between systems, and easily manage spare drives.

Pre-Failure Warranty means HPE Insight Manager not only reports when a drive is going to fail but allows replacement of failing drives prior to actual failure. For complete details, consult the HPE Support Center or refer to your HPE Server documentation.

• x8 PCIe 3.0 host interface provides maximum bandwidth
• Read ahead caching
• Write-back caching (with FBWC)

Native Command Queuing

Native Command Queuing (NCQ) is a technology designed to increase performance of SATA hard disk drives by allowing the individual hard disk to internally optimize the order in which received read and write commands are executed. This can reduce the amount of unnecessary going back-and-forth on the drive's heads, resulting in increased performance for workloads where multiple simultaneous read/write requests are outstanding, most often occurring in server or storage-type applications. Without NCQ the drive has to process and complete one command at a time. For NCQ to be enabled, it must be supported and turned on in the controller and in the hard drive itself.
NOTE: Please see the SATA Hard Drive QuickSpecs for specific SATA hard drive capacities that support NCQ: https://www.hpe.com/h20195/v2/gethtml.aspx?docname=c04111725

Capacity

Given the increasing need for high performance and rapid capacity expansion, the SA-P420 Controller offers:

• Up to 240TB of total internal storage with 60 x 4TB LFF SATA hard drives
• Up to 24TB of total internal storage with 27 x 900GB SFF SAS hard drives

Above stated total internal storage LFF is based on the HPE SL4540 Gen8 server. Maximum internal storage is dependent on the server.

• Online RAID level migration between any RAID levels (with FBWC )
• Online stripe size migration
• Online capacity expansion
• Online logical drive extension
• Online active drive replacement
• Online drive firmware upgrade
• Unlimited global online spare
• Pre-Failure Warranty

Fault Prevention

The following features offer detection of possible failures before they occur, allowing preventive action to be taken:

• S.M.A.R.T.: Self Monitoring Analysis and Reporting Technology first developed at HPE detects possible hard disk failure before it occurs, allowing replacement of the hard drive before a real failure occurs.
• Drive Parameter Tracking monitors drive operational parameters, predicting failure and notifying the administrator.
• Dynamic Sector Repairing continually performs background surface scans on the hard disk drives during inactive periods and automatically remaps bad sectors, ensuring data integrity.
• Smart Array Cache Tracking monitors integrity of controller cache, allowing pre-failure preventative maintenance.

Fault Tolerance

Keeps data available and server running while a failed drive is being replaced; several fault tolerance configurations are supported including:

• RAID 6 (Advanced Data Guarding): Supported with a minimum of 4 drives. This allocates two sets of parity data across drives. This level of fault tolerance can withstand a double drive failure without downtime or data loss.
• RAID 60: Supported with a minimum of 8 drives. This volume is composed of two or more RAID 6 sub-volumes (parity groups) where data is striped across each parity group as if it were a single physical drive. Each RAID 6 parity group can sustain up to two drive failures without incurring data loss.
• RAID 5 (Distributed Data Guarding): Supported with a minimum of 3 drives. This allocates one set of parity data across drives. This level of fault tolerance can withstand a single drive failure without downtime or data loss.
• RAID 50: Supported with a minimum of 6 drives. This volume is composed of two or more RAID 5 sub-volumes (parity groups) where data is striped across each parity group as if it were a single physical drive. Each RAID 5 parity group can sustain a single drive failure without incurring data loss.
• RAID 1 & 10 (Drive Mirroring): Supported with a minimum of 2 drives. This allocates half of the drive array to the data and the other half to the mirrored data, providing two copies of the data.
• RAID 1 ADM & 10 ADM (Advanced Data Mirroring): Supported with a minimum of 3 drives. RAID 1 ADM creates redundant copies of the data using 3 drives. RAID 10 ADM stripes data across two or more sets of RAID 1 ADM volumes. This level of fault tolerance can withstand a double drive failure within a RAID 1 ADM volume without downtime or data loss.

Fault Recovery

Minimizes downtime, reconstructs data, and facilitates a quick recovery from drive failure

• Recovery ROM: This feature protects the user from a firmware image corruption by storing a redundant copy of the firmware image. If the active firmware image becomes corrupt, the controller will use the redundant firmware image and continue operating.
• On-Line Spares: There is no limit to the number of spare drives that can be installed prior to drive failure. If a failure occurs, recovery begins with an On-Line Spare and data is reconstructed automatically.
• DRAM ECC detects and corrects data bit errors.
• Battery-backed write cache upgrade provides for up to two days of battery power for data cache retention. The data backup duration could be extended anytime the server's auxiliary power is available during system power down.

Ease of Use

Consistency and upgradeability on most current shipping Smart Array products make them unique in the industry:

• GUI based configuration, management and diagnostic software tools with the HPE Smart Storage Administrator
• Common data format between generations of products
• Data migration between servers and external Modular Smart Array enclosures

HPE SSD Smart Path

The HPE SSD Smart Path feature included in the Smart Array software stack improves Solid State Disk (SSD) read performance. With up to 4x better SSD read performance, HPE SSD Smart path chooses the optimum path to the SSD and accelerates reads for all RAID levels and RAID 0 writes. HPE SSD Smart Path Requires updated firmware, drivers, and configuration utility available at http://www.hp.com/go/ssdsmartpath. HPE SSD Smart Path is ideal for read intensive workloads and is included as a base feature on HPE Smart Array P-series controllers. The following operating systems are supported by the HPE SSD Smart Path feature:

• Microsoft Windows Server 2008
• Microsoft Windows Server 2008 R2
• Microsoft Windows Server 2012
• Microsoft Windows Server 2012 R2

• SUSE Linux Enterprise Server 11 (SP1, SP2, SPA)
• VMware ESXi 5.0  U3
• VMware vSphere 5.1 U2 and vSphere 5.5

HPE SmartCache

The HPE SmartCache licensed feature is a controller-based read caching solution in a DAS environment that caches the most frequently accessed data ("hot" data) onto lower latency SSDs to dynamically accelerate application workloads. The HPE SmartCache architecture is flexible and supports any HPE ProLiant Gen8 supported HDD for bulk storage and any HPE ProLiant Gen8 supported SSD as an accelerator.

HPE SmartCache is deployed and managed using the HPE Smart Storage Administrator (HPE SSA) and HPE Array Configuration Utility (HPE ACU).

The basic HPE SmartCache architecture is comprised of the following three elements:

• Bulk storage: The first element is the bulk storage device, which is any supported HDD attached to the HPE Smart Array controller.
• Accelerator: The second element, the accelerator, is a faster/lower latency SSD device that caches data.
• Metadata: The final element is metadata, information held in a relatively small storage area that maps the location of information residing on the accelerator and bulk storage devices.
