Definition of Throughput: Throughput refers to the amount of data transferred from or to the storage system over a specific period. It is measured in units such as MB/s or GB/s.

Relevance to Performance Diagnosis: When diagnosing performance issues on an E-Series storage system, measuring throughput over an hour helps determine the data handling capacity of the system. This metric can reveal whether the system is processing data efficiently or if there are bottlenecks.

Methodology: Tools within the SANtricity System Manager can be used to monitor and log throughput, providing insights into the performance characteristics and potential areas needing optimization.

CHAP (Challenge Handshake Authentication Protocol): CHAP is a protocol used to authenticate the identity of an initiator or target in iSCSI communications. This ensures that only authorized devices can connect to the storage array over the iSCSI network.

Implementation in E-Series: In the context of E-Series systems, CHAP secrets are configured to provide an additional layer of security by requiring both the initiator and target to authenticate each other using a shared secret before establishing an iSCSI session.

Exhibit Analysis: The exhibit shows the rear view of an E-Series controller with various ports.

SAS expansion ports: 2 ports (EXP1 and EXP2).

SAS host ports: 6 ports.

FC/iSCSI ports: 2 ports (these ports can be configured as either FC or iSCSI).

Reference: NetApp E-Series hardware manual and port configuration guides.

Understanding the Requirements: The administrator needs to provision a 1 TB volume for non-critical temporary data that requires the highest possible IOPS.

Non-Critical Data: Since the data is non-critical, redundancy (data protection) is not the primary concern. Therefore, RAID 0, which does not provide redundancy but maximizes performance, is suitable.

Highest Possible IOPS: RAID 0 is known for providing the highest IOPS compared to other RAID levels because it stripes data across multiple disks, allowing simultaneous read/write operations.

Segment Size: A smaller segment size (32 KiB) will result in higher IOPS for small random I/O operations, which is typical in seismic-analysis applications.
