Top-of-the-line blade storage scalability
 

Each module of the Sun Blade 6000 Disk Module and the Sun Blade 6000 Multi-Fabric Network Express Module (NEM+) just announced by Sun can provide up to 1.17TB of direct attach storage space for the Sun Blade 6000 Modular System, conveniently and cost effectively without either the cost or the management overhead that come with external storage. The Sun Blade 6000 Disk Module supports such storage-hungry applications as file service, MySQL and many other web infrastructure applications.

The high density blade form factor design of this solution makes it possible to employ up to five storage modules in a single Sun Blade 6000 Modular System with up to eight SAS or SATA SFF disk drives per module.The serial attach SCSI interface is rated at 73G/15,000 rpm; 73GB/10,000 rpm and 146GB/10,000 rpm.

The solution works with two 3.0 Gb/s SAS interfaces to midplane for routing to Network Express Module Gigabit Ethernet and SAS; in addition, 1.5 Gb/s Serial ATA is supported via SATA Tunneling Protocol.

Physical management is accomplished with in-band SCSI enclosure service via a chassis management module, and logical management is accomplished through in-band via an on-board SAS controller of the assigned server module. The Sun Blade 6000 Disk Module has 8 drive slots for 2.5-inch drives. All drives are front accessible and hot pluggable. All 2.5-inch drives with Marlin bracket that are qualified on Sun servers can be used with Sun Blade Disk Module. This greatly improve sparing efficiency, as the same drive can used with server module or disk module.

At first release, one-to-one zoning is supported, which means one Sun Blade Server Module can directly attach to an adjacent Sun Blade Disk Modules by using on-board LSI 1068E or RAID Expansion Module through the SAS expander switch embedded in the Network Express Modules. There is no need to use SAS HBA because SAS links are designed into the mid-plane of Sun Blade 6000 Modular System.

Sun's Common Array Manager, commonly used to manage Sun's storage solutions, running on the server modules, can quickly identify the existence of Sun Blade Disk Module and map the available capacity to host OS.

In the near future, a firmware update will enable each server module to scale up to 3 Sun Blade 6000 Disk Modules, adding up to 3.5TB storage per server module. This upcoming firmware update will also enable a Sun Blade 6000 Disk Module to be shared by up to 8 server modules. When used with high performance high core-density server modules such as the Sun Blade X6220, X6250 and X6450, the Sun Blade 6000 Disk Module can also be used as bootable drive.

Given that up to eight drives of storage can be added to each Sun Blade 6000 server module for a total of 12 drives or 1.75TB of available storage, the solution is easily the best-in-class for blade storage scalability, the best in the industry with 50% more storage capacity than HP and 200% more than IBM.

Furthermore, the dramatically reduced complexity of the Sun Blade 6000 Disk Module, which can be easily inserted, means there is no need for costly and complicated external storage options.

The Sun Blade 6000 Disk Module can provide high capacity boot drive and persistent storage space for Sun Blade X6220, X6450 and X6450 high performance diskless server modules. It is also a ZFS Enabler, offering superior data scalability and data integrity with break-through performance via ZFS.
