Description
Redundancy and High Availability Features
The IBM System Storage EXP3524 is a 24-bay storage expansion unit that provides both redundancy and high availability features to ensure data availability and minimize downtime in case of component failure.
Here are the redundancy and high availability features of the IBM 1746A4E System Storage EXP3524:
- Dual Redundant Power Supplies: The EXP3524 has two power supplies, each with its own power cord, to provide redundant power to the system. If one power supply fails, the other will take over and provide power to the unit.
- Hot-swappable Components: The storage enclosure is designed with hot-swappable components, such as hard disk drives and power supplies, which can be replaced without shutting down the entire system. This allows for maintenance or replacement of failed components without causing downtime for the system.
- RAID Support: The EXP3524 supports RAID levels 0, 1, 5, 6, 10, 50, and 60, which provide data redundancy and protect against data loss due to drive failures. RAID can be configured to automatically rebuild data to a spare disk if a disk fails.
- Dual-ported SAS Disks: The EXP3524 supports dual-ported SAS disks, which provide redundant data paths to the disks. This ensures data availability and eliminates the risk of data loss due to a single point of failure.
- Battery Backup: The storage enclosure has a built-in battery backup unit that provides power to the cache memory in case of a power failure. This ensures that data in the cache memory is not lost during a power outage.
- Dynamic Disk Pooling: The EXP3524 supports dynamic disk pooling, which allows administrators to create a virtual pool of disks that can be allocated to different RAID sets. This provides greater flexibility in allocating storage resources and helps to improve storage efficiency.
Performance Metrics and Benchmarking
Performance Metrics:
- Capacity: The IBM 24 Bay System Storage Exp3524 Storage Expansion Unit Model E4a Storage Enclosure can support up to 24 hot-swappable drives, providing a total storage capacity of up to 72 TB.
- Data Transfer Rate: The data transfer rate for the IBM 24 Bay System Storage Exp3524 Storage Expansion Unit Model E4a Storage Enclosure is up to 6 Gbps per drive, allowing for fast and efficient data transfer.
- RAID Levels: The IBM 24 Bay System Storage Exp3524 Storage Expansion Unit Model E4a Storage Enclosure supports multiple RAID levels, including RAID 0, 1, 5, 6, and 10, providing users with a range of options for data protection and performance.
- Hot-swappable Drives: The IBM 24 Bay System Storage Exp3524 Storage Expansion Unit Model E4a Storage Enclosure features hot-swappable drives, which means that drives can be replaced while the system is running without any downtime.
Benchmarking:
- IOPS (Input/Output Operations Per Second): The IBM 24 Bay System Storage Exp3524 Storage Expansion Unit Model E4a Storage Enclosure can achieve up to 16,000 IOPS, which is a measure of the number of input/output operations that can be performed per second.
- Latency: The IBM 24 Bay System Storage Exp3524 Storage Expansion Unit Model E4a Storage Enclosure has low latency, meaning that there is minimal delay between a request for data and the delivery of that data.
- Throughput: The IBM 24 Bay System Storage Exp3524 Storage Expansion Unit Model E4a Storage Enclosure can achieve high throughput, which is a measure of the amount of data that can be transferred per unit of time.
- Reliability: The IBM 24 Bay System Storage Exp3524 Storage Expansion Unit Model E4a Storage Enclosure is highly reliable, with features such as redundant power supplies and fans, hot-swappable drives, and advanced RAID options to protect against data loss.
Energy Efficiency and Environmental Considerations
The IBM 24 Bay System Storage Exp3524 Storage Expansion Unit Model E4a Storage Enclosure is designed with energy efficiency and environmental considerations in mind. This unit features a highly efficient power supply that minimizes power consumption, reducing the overall energy footprint of the system.
In addition, the enclosure is designed to be highly modular, allowing for easy upgrades and maintenance without the need to replace the entire unit. This reduces waste and helps to extend the lifespan of the system, further reducing its environmental impact.
The enclosure is also designed with noise reduction in mind, with carefully selected fan placement and acoustical materials used to minimize noise levels. This makes the unit ideal for use in quiet environments such as offices or data centers where noise pollution can be a concern.
