Smart Array P222

SAS-SATA Controller - Smart Array P222

Overview

SAS (Serial Attached SCSI) and SATA (Serial ATA) controllers are critical components in server storage systems, designed to manage and control multiple hard drives or solid-state drives (SSDs). These controllers facilitate communication between storage devices and the server's motherboard, ensuring data is transmitted efficiently and reliably. SAS controllers are preferred for high-performance enterprise environments due to their faster data transfer rates and support for larger, more reliable disk arrays. SATA, while offering lower speeds, is commonly used in cost-sensitive applications where high capacity and moderate performance are sufficient. The SAS-SATA controller is often the backbone of RAID (Redundant Array of Independent Disks) configurations, providing fault tolerance, redundancy, and enhanced storage management features.

Smart Array P222 - Product Overview

The Smart Array P222 is an advanced SAS/SATA controller from HPE (Hewlett Packard Enterprise), offering a high-performance solution for managing storage in enterprise environments. Designed for use with HPE servers, this controller provides flexibility in managing both SAS and SATA drives, delivering reliable, high-performance storage solutions for a wide range of applications, from general server usage to mission-critical environments.

Key Features of the Smart Array P222

• Dual-Channel Support: The Smart Array P222 supports both SAS and SATA drives, allowing for maximum flexibility in storage configurations. This dual support enables businesses to optimize their storage infrastructure for different needs.
• RAID Support: The P222 supports multiple RAID levels, including RAID 0, 1, 5, 6, 10, 50, and 60, providing enhanced performance, fault tolerance, and redundancy for critical storage environments.
• Scalability: With support for up to 8 internal SAS/SATA drives and the ability to connect external drives through an additional port, the P222 is highly scalable, capable of growing with your storage requirements.
• Advanced Data Protection: With built-in data protection features like RAID 1, RAID 5, and RAID 6, the P222 ensures that data is safe and that the system remains operational even in the event of hardware failures.
• Cache Options: The P222 supports cache configurations that help increase system performance by storing frequently accessed data in memory, reducing access times and boosting throughput.

Performance Characteristics

Data Transfer Rate

One of the primary advantages of the Smart Array P222 is its high data transfer rate. Supporting up to 6Gbps per port for both SAS and SATA connections, it ensures rapid data access and optimal performance for servers running data-intensive applications. The P222 is engineered to handle complex workloads, making it an excellent choice for database servers, virtualization environments, and large-scale storage systems.

RAID Array Management

Managing RAID arrays with the Smart Array P222 is simplified through HPE's Smart Storage Administrator (SSA) software, which provides a user-friendly interface for configuring and monitoring the array. Whether you need to create a basic RAID 1 mirror or configure a more advanced RAID 6 setup for high availability, SSA makes it easy to manage storage arrays efficiently.

RAID Levels Supported by the P222

• RAID 0: Striping with no redundancy for maximum performance and full utilization of disk space.
• RAID 1: Mirroring for redundancy, where data is duplicated across two drives for failover protection.
• RAID 5: Striping with parity, providing a balance between performance, redundancy, and storage efficiency.
• RAID 6: Double parity, offering additional fault tolerance over RAID 5 for environments where data availability is critical.
• RAID 10: Combining RAID 1 and RAID 0 for both redundancy and performance, commonly used in high-demand environments.
• RAID 50 and RAID 60: Combinations of RAID 5 and RAID 0 or RAID 6 and RAID 0, offering improved performance and redundancy for large-scale deployments.

Compatibility

Hardware Compatibility

The Smart Array P222 is compatible with a wide range of HPE servers, including ProLiant and BladeSystem models. This broad compatibility ensures that the P222 can be seamlessly integrated into existing IT infrastructures. It is also backward compatible with SAS-2 (6Gbps) devices, ensuring that older SAS devices can be used with the controller while still benefiting from the newer technology's advantages.

Security and Data Protection

Built-in Security Features

Data security is a top priority for businesses, and the Smart Array P222 delivers on that front with several key features designed to protect your data. Built-in support for S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) ensures that your storage drives are constantly monitored for potential failures, allowing for proactive measures before data loss occurs. Additionally, support for encryption features, including HPE's Data Encryption for SAS SSDs, allows for secure data storage in transit and at rest.

RAID Data Protection

The P222 supports various RAID configurations that offer varying levels of data protection. RAID 1 and RAID 5 provide redundancy in the form of mirrored or striped and parity-protected data, ensuring that your system can recover from disk failures without compromising data integrity. RAID 6 provides even more robust fault tolerance with double parity, ensuring your system remains operational even if two drives fail simultaneously.

Enhanced Redundancy with Hot Spares

Another notable feature of the Smart Array P222 is the ability to configure hot spares. These are idle disks that remain ready to automatically replace failed drives in a RAID array. This feature helps reduce downtime and ensures that your data is always protected, even in the event of multiple disk failures.

Support and Firmware Updates

Regular Firmware Updates

HPE provides regular firmware and driver updates for the Smart Array P222 to ensure the controller remains compatible with the latest hardware and software technologies.
