ideal platform to build robust storage clusters running the LeftHand Networks SAN/iQ® software. LeftHand's SAN/iQ software platform delivers enterprise-class SAN functionality on industry standard hardware. This document provides an overview of the performance characteristics your applications can - HP LeftHand P4000 | HP LeftHand SAN Solutions - Application Notes - NSM 2120-G2 - Page 6
closely resembles your own data requirements. Performance Tuning Tips SAN performance can be negatively impacted if the SAN is not configured properly. The following guidelines will help maximize the performance of the LeftHand Networks SAN. Network Best Practices • Use Gigabit Ethernet switching - HP LeftHand P4000 | HP LeftHand SAN Solutions - Application Notes - NSM 2120-G2 - Page 7
. Storage Node Configuration Best Practices • Bond networks interfaces for network redundancy and more bandwidth using Adaptive Load Balancing (ALB). • Use RAID level 5 or 10 for disk redundancy within storage modules. • Enable SAN/iQ iSCSI Load Balancing on authentication groups for Windows servers - HP LeftHand P4000 | HP LeftHand SAN Solutions - Application Notes - NSM 2120-G2 - Page 8
NICs for the storage traffic. A single 24 port Gigabit switch was used for all tests. All disk volumes were configured using the Microsoft iSCSI Software Initiator Version 2.0.4. Volumes were mounted using the Windows Logical Disk Manager and formatted with NTFS using the default allocation unit - HP LeftHand P4000 | HP LeftHand SAN Solutions - Application Notes - NSM 2120-G2 - Page 9
nature of low queue depth disk operations, the architecture of a LeftHand Networks SAN solution is capable of handling multiple file copy jobs simultaneously without degrading performance. This is represented by the "Concurrent Jobs" set of data. Best Practice - When copying from DAS to the iSCSI - HP LeftHand P4000 | HP LeftHand SAN Solutions - Application Notes - NSM 2120-G2 - Page 10
