IxLoad iscsi Emulation

Transcription

1 IxLoad iscsi Emulation The iscsi (Internet Small Computer System Interface) is a Storage Area Network (SAN) protocol used for transferring data to and from networked storage devices. iscsi uses SCSI commands over TCP/IP to enable networked storage devices to behave as though they are locally attached. Traditionally SCSI commands are transported over dedicated Fibre Channel networks. IxLoad delivers a scalable iscsi emulation to validate the performance and capacity of storage target devices, WAN Acceleration, and storage switches. Features Stateful iscsi Initiator and Target emulations Authentication method: CHAP with MD5 or None Automatic discovery of the external Targets Complete flexibility to control the I/O operations o Read/Write distribution o User can control the number of SCSI Read and Writes needed to complete a high-level IO o Flexibility introduced to have randomness in Logical Block Address access within an IO. o Ability to specify Alignment Block sizes per SCSI read/write commands Data integrity validation with Ixia pattern and user specified 32 Bit data pattern Customizable target portal with arbitrary Target LUNs and capacity IxLoad is used to: Figure 1. iscsi Storage Target Use Case Benchmark the performance of SAN arrays Determine the iscsi target s capacity and behavior at high load conditions Validate the throughput and I/O responsiveness in different system configurations Test networks in a combination of iscsi and background traffic, introducing congestion in order to test the effect of the QoS policies on iscsi response times Agoura Road Calabasas, CA USA Tel Document No.: Rev C December Page 1
