Page 3: Executive Summary
The xStack Storage Series iSCSI storage arrays from D-Link provide cost-effective, easy-to- deploy shared storage solutions for applications like the VMware Infrastructure 3 server virtualization software. In this document the features and performance of the D-Link xStack Storage™ Series iSCSI storage arrays along with typical server systems are configured, instructions for use with VMware are given, and recommendations are made. - Page 4 Our virtualized storage pool eliminates the complexities associated with managing traditional RAID. Best of all, D-Link’s iSCSI storage arrays are affordable. Provision your storage from a single pool of available storage. There is no need to dedicate drive groups or entire arrays to RAID types or manage individual LUNS.

For testing this basic setup, two Windows Server 2003 R2 VMs with Microsoft SQL Server 2005 running a medium size (1 GB) version of the D-Link DVD Store database test application were created with their 10GB virtual disks stored on the five-disk LUN on one array. The VMs were then cloned three times with the copies’... - Page 10 Storage DSN-Series SAN Arrays VMware ESX 3.0.2 & 3.5 Figure 4: Basic Setup (typical servers, switch and xStack Storage DSN-3200-10 iSCSI SAN Solution) D-Link Systems, Inc.

- Page 11 With the introduction of VMware Virtual Infrastructure 3.0, several new storage connectivity options were introduced. This section covers the available storage options and reviews settings specific to each technology. To add a LUN as a datastore, follow these steps. Figure 5: Add Storage D-Link Systems, Inc.

- Page 12 Figure 6: Disk/LUN Formatting iSCSI/IP SAN Connectivity As a best practice, D-Link recommends separating iSCSI traffic from other IP network traffic by implementing a separate network or VLAN than the one used for VMotion or virtual machine traffic. To enable ISCSI connectivity, the ESX Server requires a special connection type, referred to as a VMkernel port, along with a service console port.

For larger deployments, scalability benefits may be realized in storage performance by implementing iSCSI HBAs. Note that this statement is not a requirement or a recommendation, but rather a consideration when designing dense storage solutions.

Expertise may be required to solve user-specific deployments. Conclusions and Recommendations In conclusion, the D-Link xStack Storage series SAN is an excellent value for the money and offers high end features with a reasonable price tag. Combine it with VMWare ESX (or other virtual) server, and you have the major tools you need to build a state-of-the-art server environment without breaking your budget. - Page 23 Storage DSN-Series SAN Arrays VMware ESX 3.0.2 & 3.5 The D-Link xStack Storage Series is a good entry level iSCSI solution and is ideal for customers who have file-intensive environments and are looking to deploy virtualization for a small subset of application data.
