1 Best Practices for the Sun StorEdge 3510 FC Array This document highlights Fibre Channel (FC) best practices which apply to the Sun StorEdge 3510 FC array .
2 Sun StorEdge 3000 Family Best Practices Manual • October 2003 Intr oduction There ar e two popular methods for connecting storage to servers. ■ The original and still most widely used approach uses a direct connection between a server and its storage system.
Best Practices f or the Sun StorEdge 3510 FC Array 3 Overview Fibr e Channel Architectur e The Sun StorEdge 3510 FC array RAID controller has six f ibre channels that can support 1 or 2 Gb data transfer speeds. RAID controller channels 0, 1, 4, and 5 are normally designated for connection to hosts or Fibre Channel switches.
4 Sun StorEdge 3000 Family Best Practices Manual • October 2003 In a point-to-point configuration, only one ID can be assigned to each host channel. If more than one ID is assigned, the point-to-point protocol rules ar e violated. Any host channel with more than one ID will not be able to log in to an FC switch in fabric mode.
Best Practices f or the Sun StorEdge 3510 FC Array 5 W ith at least one LD assigned to each controller , both contr ollers are active. This configuration is known as an active-active controller conf iguration and allows maximum use of a dual controller array's r esources.
6 Sun StorEdge 3000 Family Best Practices Manual • October 2003 Numerous contr oller parameters are also changed to optimize for sequential or random I/O. The change takes effect after the contr oller resets. Sequential or random optimization must be set prior to creating logical drives.
Best Practices f or the Sun StorEdge 3510 FC Array 7 ■ When your array is on a public network, it is susceptible to viruses, worms, and other malware attacks.
8 Sun StorEdge 3000 Family Best Practices Manual • October 2003 FIGURE 2 T wo DAS Configurations The actual number of servers that can be connected varies according to the number of Sun StorEdge 3510 FC array controllers.
Best Practices f or the Sun StorEdge 3510 FC Array 9 The SAN can also support multiple Sun StorEdge 3510 FC arrays. Increasing the number of StorEdge arrays makes more performance and capacity available within the storage network for sharing among the servers connected to the SAN.
10 Sun StorEdge 3000 Family Best Practices Manual • October 2003 FIGURE 3 Increasing Capacity First Steps There ar e two simple yet effective approaches for designing a Sun StorEdge 3510 FC array solution into your environment. Both methods allow for the rapid estimation of an appropriate DAS or SAN solution.
Best Practices f or the Sun StorEdge 3510 FC Array 11 environment. For envir onments with different server conf igurations, choose the solution that best matches the servers whose applications are mission-critical or most important. General Conf iguration Considerations The entry-level configuration for an FC array uses only one RAID controller .
12 Sun StorEdge 3000 Family Best Practices Manual • October 2003 Non-Redundant DAS Conf igurations Note – Using single connections between Sun StorEdge 3510 SCSI arrays and servers creates single points of failure (SPOF) that can cause interruptions in the event a connection becomes unreliable or fails.
Best Practices f or the Sun StorEdge 3510 FC Array 13 Non-Redundant DAS T ips and T echniques ■ A Sun StorEdge 3510 FC array with a single controller can be configur ed to support up to four host connections. These connections can be used in pairs, individually , or in any combination of both.
14 Sun StorEdge 3000 Family Best Practices Manual • October 2003 Non-Redundant DAS Setup Details FIGURE 5 Non-Redundant DAS Connections The general procedur e for creating this configuration follows. 1. Check the position of installed SFP modules. Move or add SFP modules as necessary to support the connections needed.
Best Practices f or the Sun StorEdge 3510 FC Array 15 5. Map Logical Drive 0 to controller channel 0. 6. Map Logical Drive 1 (if created) to controller channel 5. 7. Map Logical Drive 2 (if created) to controller channel 1. 8. Map Logical Drive 3 (if created) to controller channel 4.
16 Sun StorEdge 3000 Family Best Practices Manual • October 2003 High-A vailability DAS T ips and T echniques ■ A Sun StorEdge 3510 FC array with two controllers can be conf igured to support up to eight host connections. These connections can be used in pairs for redundancy , individually or in any combination of both.

Check the position of installed SFP modules. Move them as necessary to support the connections needed.
18 Sun StorEdge 3000 Family Best Practices Manual • October 2003 2. Connect expansion units if needed. 3. Conf igure cache optimization. 4. Ensure f ibre connection is set to loop mode. 5. Conf igure target IDs. 6. Create one Logical Drive for each server and conf igure spare disks.
