Scaling Storage Networks
This guide lists the issues involved in scaling storage networks. Each chapter offers buying points and specifications for products that can help a storage administrator scale their storage network.
Switches are used to segregate network traffic, ensuring that data on one network segment is only passed to the segment that leads to an intended destination. This helps to organize the network and reduce unneeded traffic to other nodes. This segment will first focus on specific considerations for director-class 4 Gbit FC switches. After that, you'll also find a series of specifications to help make on-the-spot product comparisons between vendors.
This Buying Guide is intended to help clarify the principle considerations involved scaling storage networks and each chapter offers a set of buying points and product specifications that can help readers identify prospective new scaling products.
Choosing an IP storage switch or router will have a profound impact on your IP storage implementation. While the actual product list is relatively small -- dominated by well-established communication vendors -- the choice of an IP switch or router demands careful consideration of issues including port speed, segmentation, interoperability, security, and application compatibility. This segment will first focus on specific considerations for IP storage switches and routers. After that, you'll also find a series of specifications to help make on-the-spot product comparisons between vendors.
ISCSI SANs are quickly gaining acceptance in small business and enterprise environments, spurred on by the simplicity, low cost, and ubiquitous availability of Ethernet networks. Still, the benefits of iSCSI are often tempered by performance limitations when iSCSI storage traffic is added on top of everyday user LAN traffic. One means of improving iSCSI traffic performance is to include TOE (TCI/IP Offload Engine) capability on the Ethernet card itself. This chapter covers the specific considerations involved in iSCSI TOE cards. Following the considerations, you'll find a series of specifications to help make on-the-spot product comparisons between vendors.
