1 Real Time COPY Provide Disaster Recovery NOT to maintain two identical copies Provide I/O consistent copy of data

2 Synchronous Or Asynchronous If Within Supported Distance Use Synchronous Because: Data is more secure Best overall performance Asynchronous is supported Cases w/low I/O rates and some potentially lost data is acceptable if links are broken

SilkWorm comes with dual control units, multiple power-supplies and fans, and has two 16 port switches configured as separate fabrics. 2. CNT UltraNet Edge Storage Router 1101 are used exclusively for the communication between HP SureStore XP 128 devices. 3. Based on the design and the backbone bandwidth limitation, Asynchronous communication between the XP 128 devices was mandated by the original vendor.

6 Options For SAN Extensions (Slides by Brocade)

7 Brocade SilkWorm Multiprotocol Router Top-Level Specifications 16 ports Runs storage applications at line rate Storage processing scales linearly per-port Multiprotocol (1-2 Gbit/sec FC, IP) at each port Open API and robust storage services Core or edge deployment flexibility Compatible with 60,000 existing Brocade fabrics

8 Brocade SilkWorm Multiprotocol Router Extend SAN value to any size, over multiple networks, across distance FC-FC iscsi iscsi-to-fc Bridging Service Bridge from iscsi to Fibre Channel SANs Connect lower-cost Ethernet-connected servers to Brocade SANs FC-FC FC-FC iscsi FCIP FC-to-FC Routing Service Logically connect SAN islands Enable shared resource access across multiple fabrics Maintain administration and fault isolation of separately managed fabrics FCIP Tunneling Service Seamlessly, reliably extend Brocade SANs across MAN/WAN IP networks

9 FC-to-FC Routing enables Logical Private SANs (LSANs) Tape SAN LSAN 1 SAN Fabric LSAN 2 Database SAN Optimize utilization by consolidating and combining resources from separate SAN islands Share resources across fabrics with the management, isolation and stability of existing SAN environments Scale SANs while minimizing risk and complexity of large fabrics Protect and Extend Investment requires no changes to existing switches or edge devices Configuration and provisioning are extensions of well-understood zoning techniques

10 FC-to-FC Routing Features & Benefits Simplified management: create LSANs by defining zones that include devices on multiple fabrics. Highly scalable: build LSANs of thousands of devices without the single fabric resource constraints or the complexity and risk of merging fabrics Protects investment: no change required to existing fabrics or devices to support interconnection using the Fabric Routing Services. Highly available: multiple paths or multiple FC Routers provide highly available connectivity between fabrics, without involvement of multipath host software

11 FCIP Tunneling - Benefits FCIP Tunneling Service - Seamlessly, reliably extend Brocade SANs across MAN/WAN IP networks FCIP Some key benefits Unified SAN environment across geographies, functions, and departments Leverage IP networks for distance connectivity Foundation for business continuance and disaster recovery applications

12 iscsi Gateway Service Benefits iscsi-to-fc Gateway Service Bridge from iscsi to Fibre Channel SANs Connect lower-cost Ethernet-connected servers to Brocade SANs iscsi Some key benefits Unified SAN environment across geographies, functions, and departments Share Fibre Channel resources with low-cost servers using Ethernet networks Extended access of valuable SAN assets through an iscsi gateway
