Q:
What is the Sun StorageTek 9980 system?
A:
The Sun StorageTek 9980 system is designed for environments requiring the highest levels of performance, availability and capacity. It offers extreme scalability up to 147.5 TB along with storage virtualization and is ideal for large-scale consolidation and data-intensive applications.

The Sun StorageTek 9980 system provides extreme levels of performance and capacity for the largest data center environments. This highly available and massively scalable storage system has a base configuration consisting of two frames: the Control Frame and Array Frame. The Control Frame contains the cache and switch modules, host and drive interfaces, disk array processors, and the service processor. Up to four Array Frames can be supported, each with redundant power supplies and up to 256 drives. The system's virtualization capabilities allow storage consolidation, which helps to reduce TCO by enabling connections to multiple hosts and allows for more flexibility in configuring a SAN infrastructure. The storage system is easy to operate and control and helps to simplify data management. Software is available to support key storage applications typically used in data center environments including path management, real time replication, and remote mirroring for disaster recovery.

Q:
What is virtualization?
A:
Storage virtualization provides the ability for storage resources to precisely match the requirements of business applications. It essentially removes the physical barriers and presents a logical view. The logical view presented masks the characteristics and complexities of the underlying storage. This creates a physical view to virtual mapping that insulates users and applications from changes to their storage architecture. This de-coupling of storage and server architectures allows administrators greater flexibility and maximizes the availability and utilization of the storage environment.

Q:
How do the Sun StorageTek 9970 and 9980 systems use virtualization?
A:
Virtualization on the Sun StorageTek 9970 and 9980 systems is performed at port level, thus allowing convenient and flexible sharing of multiple heterogeneous connections. Sun StorageTek 9970 and 9980 systems offer a virtualization assist layer to ease storage management and better utilize resources. Host Storage Domains allow host pooling at the Logical Unit level for optimized connectivity. Sun StorageTek 9900 Priority Access software helps guarantee that the most critical applications get the highest level of service, while Sun StorageTek 9900 SANtinel software helps ensure only authorized access. This combination of Host Storage Domains, Sun StorageTek 9900 Priority Access software, and Sun StorageTek 9900 SANtinel software form the basis for a revolutionary virtualization assist layer, helping to enable simplified management, better utilization of storage resources, and massive consolidation.

Q:
How does the virtualization of the new Sun StorageTek 9900 series compare to that of the Sun StorageTek 6900 series?
A:
The new Sun StorageTek 9900 series provides virtualization features via software that is embedded in the array. The Sun StorageTek 6900 series' virtualization is enabled through hardware that sits between the host and the Sun StorageTek 6900.

Q:
Why would I want to use virtualization in a storage environment?
A:
  • To achieve greater storage efficiency (where the majority of virtualization is today). You want to be more efficient with physical resources. Virtualization delivers the promise of SAN benefits. It allows you to more efficiently distribute storage to applications and servers. For example, you might have one server that is only using 30 percent of the capacity attached to it. Another server is out of capacity about every three months. You have to keep adding resources to that server. A more efficient way to solve this capacity issue is to allocate the unused resources from the first server to the second server. Virtualization lets you do this easier and in a more flexible manner.
  • To simplify storage management. For example, your database is consuming data at an alarming rate, outstripping the storage that has been physically allocated to it. You can add more storage to it, but how do you make the new storage look like a seamless expansion of the data it already has? Virtualization let's you achieve this.
  • For configuration flexibility. Virtualization gives you the flexibility to change configurations to match business needs -- mapping physical resources to match performance and other storage requirements. You can arrange the configuration to look the way it needs to look for specific application requirements. For example, one application requires super-fast access. Another application requires absolute security. A third application just needs storage -- and a lot of it. You can configure your device and storage metrics to meet all these various application requirements. Virtualization insulates you from changes, translating into a lower overall total cost of ownership (TCO).

Q:
When would you use virtualization?
A:
You would use virtualization in any SAN environment where you want to maximize use of your resources or where you are running into capacity issues in your existing infrastructure. You would also use virtualization as a means to reduce TCO and in any heterogeneous host storage environment.

Q:
With Host Storage Domains security being performed at the WWN level, does this mean that the Sun StorageTek 9980 system supports 64 WWNs?
A:
No. Each FC-AL port on the Sun StorageTek 9980 and 9970 systems supports 128 WWNs. This means that you may have up to 8,192 WWNs on a Sun StorageTek 9980 system and up to 6,144 WWNs on a Sun StorageTek 9970 system.
