Description
Performance Benchmarks and Testing Results
The IBM System Storage EXP2524 Express is a 2U rack-mountable storage enclosure designed to provide high-density storage capacity for IBM System x and BladeCenter server environments. It is capable of supporting up to 24 hot-swappable 2.5-inch SAS or SATA hard disk drives, and can be configured with various RAID levels to provide data redundancy and improve performance.
The performance benchmarks and testing results of the IBM System Storage EXP2524 Express can vary depending on the specific configuration and workload being tested. However, IBM provides several published benchmarks and testing results for the storage enclosure.
One of the most common benchmarks used to evaluate storage performance is the Storage Performance Council (SPC) Benchmark 1, which measures the I/O operations per second (IOPS) and response times of storage systems. According to the SPC-1 benchmark results published by IBM for the EXP2524, the storage enclosure achieved a maximum of 33,521.47 SPC-1 IOPS with an average response time of 6.06 milliseconds.
In addition to the SPC-1 benchmark, IBM has also published results for other performance tests, such as the Oracle E-Business Suite R12 Order-to-Cash benchmark, which measures the performance of a database application running on a storage system. In this benchmark, the EXP2524 achieved a maximum of 1,440 Order-to-Cash users with an average response time of 1.78 seconds.
Security and Data Protection Features
The 174724X IBM System Storage Exp2524 Express Storage Enclosure is a high-performance storage solution that offers robust security and data protection features to safeguard critical business data. Some of the security and data protection features of this storage enclosure include:
- Encryption: The 174724X IBM System Storage Exp2524 Express Storage Enclosure supports self-encrypting drives (SEDs) that offer hardware-based encryption to protect sensitive data at rest.
- Authentication: The storage enclosure provides support for multiple authentication methods, including LDAP and RADIUS, to control access to the system.
- Data backup and recovery: The storage enclosure comes with built-in backup and recovery capabilities, allowing businesses to quickly recover lost or corrupted data.
- RAID protection: The 174724X IBM System Storage Exp2524 Express Storage Enclosure supports RAID levels 0, 1, 5, 6, 10, and 50, which provide redundancy and protection against data loss due to drive failure.
- Redundant components: The storage enclosure features redundant power supplies and fans, ensuring continuous availability of critical data.
- Secure erase: The storage enclosure supports secure erase, a feature that permanently erases data from hard drives, making it virtually impossible to recover.
- Management and monitoring: The storage enclosure provides a comprehensive management and monitoring interface that allows IT administrators to monitor the health of the system, configure settings, and manage alerts and notifications.
Redundancy and High Availability Features
The 174724X IBM System Storage Exp2524 Express Storage Enclosure is designed with redundancy and high availability features to ensure data protection, minimize downtime, and enhance system performance.
- Redundant Power Supplies: The storage enclosure features dual power supplies that are hot-swappable and can provide power redundancy. In case of a power supply failure, the other power supply can automatically take over, preventing any disruption to the system’s operations.
- Redundant Cooling Fans: The storage enclosure is equipped with redundant cooling fans that are hot-swappable. In case of a fan failure, the remaining fans can operate at maximum speed to ensure that the system stays cool and operates efficiently.
- RAID Technology: The storage enclosure uses RAID (redundant array of independent disks) technology to protect data from disk failure. RAID levels such as RAID 1, 5, 6, and 10 can be configured for data redundancy and data protection.
- Hot-Swappable Disk Drives: The storage enclosure supports hot-swappable disk drives, which means that you can replace a failed drive without shutting down the system. This feature minimizes downtime and allows the system to keep running without interruption.
- Dynamic Expansion: The storage enclosure supports dynamic expansion, allowing you to add more disk drives or expand storage capacity on the fly. This feature ensures that your system can accommodate changing business needs without disrupting system performance.
- High Availability: The storage enclosure is designed for high availability, providing uninterrupted access to data even in the event of a failure. This is achieved through features such as hot-swappable components, redundant power supplies, and RAID technology.
