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 . Overview The Sun StorEdge 3510 array is a next generation Fibre Channel storage system designed to provide dir ect attached storage (DAS) to entry-level, mid-range, and enterprise servers[...]

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. A storage system connected in this manner is commonly referred to as dir ect-attached[...]

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. RAID controller channels[...]

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. This “ one-ID-per[...]

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. Each LD can be partitioned in up to 128 separate partitions or used as a[...]

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. There ar e two limitations that apply to the optimization m[...]

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. ■ A variety of security software is available to detect and mitigate these attacks. Some port-scanning and other security software can have an adverse impact on your ability to access dat[...]

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. It also depends on the quantity of Fibre Channel connections used for each server and the total number of small form-factor pl[...]

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. A SAN also provides gr eat flexibility in how storage capacity can b[...]

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. Regardless of which method is used, t[...]
