To demonstrate how iSCSI failover functions, several companies participated in a third party demonstration where 5 videos where streamed from 5 iSCSI storage targets on an ISCSI intelligent storage switch
to 5 Microsoft Windows 2003 hosts.
Driven by the ever-increasing demand for storage from corporate applications, storage vendors are today preparing SAN infrastructure components that will double the speed of today's 2 Gb/s storage switches
and the host bus adapters (HBAs).
To demonstrate how iSCSI failover functions, several companies participated in a third-party demonstration where five videos were streamed from five iSCSI storage targets on an iSCSI intelligent storage switch
to five Microsoft Windows 2003 hosts (Figure 4).
Some of the issues for which embedded storage switch
providers must supply solutions include:
Mark Ferelli: Now, when we're all looking at embedded storage switch
technology, some have preferred to buy it and others have elected to build the technology in-house.
Recently, Cisco made its entry into the Fibre Channel SAN switching market by exercising its right to acquire intelligent storage switch
developer Andiamo Systems.
All these issues have disappeared with the introduction of an embedded storage switch
on a single chip.
Alacritech and Nishan connected a server with an Alacritech Server and Storage Accelerator network interface card (NIC) to a Nishan IP Storage switch
. The test data moved over Gigabit Ethernet to a Fibre Channel SAN containing a Hitachi Freedom Storage disk subsystem.
And when you take that platform and apply sophisticated TCP processing, FC processing, block virtualization, file system technology, and the ability to translate FC to iSCSI or iSCSI to FC, you have a next generation platform that is fundamentally a multi-protocol storage switch
. To the end user it looks like a platform that allows the user to access storage, whether on Gigabit Ethernet or Fibre Channel, whether they want to access storage using block semantics or file system semantics.
The new Cisco switching products augment the Cisco Unified Fabric portfolio, which consists of Nexus data center switches and MDS storage switches
that connect servers, data storage, and corporate networks seamlessly within the data center and cloud.
It means creating segregated VLAN networks, creating and assigning data and storage switches
. And it means automatically creating and assigning boot LUNs.
