3 Introduction Sun Microsystems, Inc. Introduction (TM) The Sun Fire X4500 server delivers massive storage capacity and remarkable throughput making it an ideal nearline storage platform for backup and restore applications. Combining the power of the Solaris 10 Operating System with the data integrity and simplified administration of ZFS, the X4500 becomes an ideal candidate for streamlining and improving backup/restore operations. This paper discusses how to quickly configure the X4500 as a

The default NIC configuration on the X4500 allows up to four physical GigaBit Ethernet connections to be attached. The four connections can be utilized to back up four separate subnets, or the links can be aggregated together using dladm(1M) for improved throughput to a single subnet. Netbackup Master Serv

5 Configuration Sun Microsystems, Inc. Solaris Configuration The X4500 server used while testing for this paper was installed with Solaris 10 8/07. This is the recommended version to use with Netbackup as various ZFS improvements were introduced in this build. The X4500 has 48 500GB SATA drives. The two boot drives (c5t0d0 and c5t4d0) are mirrored using Solaris Volume Manager. The rest of the drives are available for backup data. Zpool Configuration Zpool configuration is a decision that nee

7 Configuration Sun Microsystems, Inc. Netbackup Configuration The X4500 will be configured as a Media Server. In this example, it is assumed that there is a separate Master NBU server. The Netbackup and Media Manager package must be installed on the X4500. It also will require the appropriate server licensing. It is recommended that the Master server's bp.conf file be updated with the new Media server information before installing the software on the media server. An example is shown bel

16 Frequently Asked Questions Sun Microsystems, Inc. Frequently Asked Questions Q1: How does the X4500 scale as the workload increases? A1: Testing was done to measure scalability by saturating each onboard GigE port in turn. Three Zpool configurations were tested. The RAIDZ1-6Spares (14.3TB of usuable space) configuration is the configuration listed in the example earlier in this guide. The RAIDZ1-NoSpares (16.9TB of usuable space) configuration is based on the default Zpool configuration pr

17 Frequently Asked Questions Sun Microsystems, Inc. A2: Yes. A Proof-of-Concept was done for a large customer and 10GB Ethernet was part of the testing. Using a Neterion Xframe II and the xge driver, 8 clients capable of delivering 100MB/sec each were configured to backup to a X4500. Jumbo Frames were enabled on all components. Throughput rates of 500-550 MB/sec were achieved using the Zpool/ZFS configurations mentioned above. Image duplication between two X4500 Media Servers was measured at
