摘要:
A method of configuring a blade enclosure is provided by the present invention in which, in a first step, slots are identified to whose SAS connectors SAS device blades are to be connected in a minimum capacity configuration. In a second step, slots are identified to whose SAS connectors SAS device blades are to be connected in a maximum capacity configuration. A path is then established from the SAS switch to the SAS connector of each slot identified in either the first step or the second step. Blade devices, such as RAID controller blades and disk enclosure blades are installed in the identified slots. Thus, the SAS switch within the enclosure selectively and efficiently interfaces with a predetermined number of blade slots rather than with all slots.

An apparatus, system, and method are disclosed for integrating redundant array of independent disk (“RAID”) storage within a blade center. A plurality of mutually autonomous storage subsystems mount within the blade center through a switch. Each storage subsystem includes a storage module comprising a plurality of storage devices and a RAID controller. A server blade mounted within the blade center may access a first storage subsystem through a switch module. The switch module is a non-blocking, cross-point switch. In one embodiment, the switch module restricts the server blade's access to a second storage subsystem.

An apparatus, system, and computer readable medium are disclosed for booting a server from a shared storage system. The present invention teaches at least one server having at least one processor, a storage system having a plurality of storage drives and at least one boot volume corresponding to the at least one server, and a switch fabric having at least one switch; the switch fabric isolates boot traffic form storage traffic and enables communication between the server and the boot volume of the storage system. In some embodiments the switch fabric includes one or more partitionable switches that isolate boot traffic from storage traffic. The boot volumes may be a redundant array of storage devices. In certain embodiments, the present invention also includes devices external to the server, switch fabric, and storage system.
摘要:
A blade enclosure is provided which may accommodate a first configuration which includes integrated drive enclosure blades (I-DEBs) or a second configuration which includes I-DEBs and non-integrated or switched DEBs (S-DEBs). Each I-DEB includes a pair of redundant RAID controllers, each having two configurable ports. In the first configuration, all four ports are configured as host adapter (HA) ports through which data is exchanged with server blades. In the second configuration, one port of each RAID controller is configured as an HA port, through which data is exchanged with server blades, and the other port of each RAID controller is configured as a device adapter (DA) port, through which data may be exchanged with the S-DEB. Zones may also be established to separate traffic between the servers and the I-DEB from traffic between the I-DES and the S-DEB.

An apparatus, system, and method are disclosed for integrating a blade RAID controller and storage. A storage blade enclosure communicates with a blade chassis. The storage blade enclosure is mounted within the blade chassis. A RAID controller disposed in the storage blade enclosure receives a command through the storage blade enclosure. In one embodiment, the command is communicated through the blade chassis from a processor blade mounted in the blade chassis. The RAID controller redundantly stores data to or retrieves data from a storage module disposed in the storage blade enclosure in response to the command using a RAID redundancy methodology.
