Slide1:  SAStor Customer profiles The brief descriptions and schematic diagrams in the following slides are intended to provide a simple insight into the variety of ways Baydel customers are using SAStor storage to provide them with a very high reliability and performance based storage solution at an economic cost. Slide2:  International energy company seismic database installation. Remote site Seismic database Customer requirement:- To consolidate a large volume of seismic and graphical data run on two separate SGI IRIX based systems onto centralised storage as well as adding a Solaris based database run on a Sun ‘Sparc’ machine. High reliability and Web based management were prerequisites due to the remote location of the equipment. Baydel SAStor Solution:- Baydel supplied a single SAStor storage array configured with two dual Ultra 320 SCSI controllers and fitted with a mix of 73Gb disks for the database in a RAID 10 configuration and 400 Gb disks in a RAID 5 set for the seismic and graphical data. – see schematic in the following slide. The customer chose Baydel storage because of the exceptional reliability of the previous storage arrays on the same site over many years and their very low cost of ownership.

IBM ‘Blade’ attached SAN Customer requirement:- To create a centralized storage pool to be shared by over 100 IBM ‘Blade’ servers each running its own ‘Windows’ based application and having secure private access to one or more logical disks of different capacities and I/O profiles. Scope for considerable expansion of both the number of servers and the storage, without performance loss and ease of management, was a prerequisite. Baydel SAStor Solution:- Baydel supplied a 7 Tbyte SAStor based Fiber Channel SAN. The initial installation comprised three SAStor storage arrays configured into a Qlogic 64 port ‘FC switch’ configured as a high availability matrix. A mix of 73 Gb and 400 Gb disks was used in the SAStor arrays to optimise on both performance and capacity. The initial Baydel SAN configuration allows over 1500 any size logical disks to be created and mapped to one or more individual servers. – see the schematic in the following slide. The customer chose a Baydel SAN because of its virtually unlimited linear expansion in performance, capacity, the number of accessible logical disks and ease of management.

SAStor storage with Solaris Customer requirement:- The British national daily newspaper required new storage to provide a backup/disaster recovery solution for their existing ‘production databases’ which run on a Solaris based computer system; currently using legacy Baydel storage. Baydel SAStor Solution:- Baydel provided two 4.8 Tbyte SAStor storage arrays with a total of eight Fiber Channel host ports for direct connection to two Sun V880 machines in an HA cluster. The customer specified Baydel storage to complement the Sun machines based on many years of trouble free operation when using existing Baydel storage arrays on a variety of Sun platforms. Slide7:  National ‘broadsheet’ newspaper installation SAStor storage with Solaris Slide8:  International Japanese investment bank R & D installation. Solaris SAN solution Customer requirement:- The customer required several Tbytes of additional storage to be available in a variety of differently sized, dynamically selected, logical disks connected to several Sun servers used by almost 100 clients in the R & D and software testing departments. Baydel SAStor Solution:- Baydel provided a single 4.8 Tbyte SAStor RAID array which was simply added to the Fiber Channel SAN with the potential to support over 500 logical disks. The customer specified Baydel storage to complement the Sun machines based on many years of trouble free operation when using existing Baydel storage arrays on a variety of Sun platforms. Slide9:  Solaris SAN solution International Japanese investment bank R & D installation Slide10:  Web based application server installation Application Web server Customer requirement:- The customer required a 2Tbyte storage pool to be accessed by at least seven blade servers, all running ‘PolyServe’ and supporting both databases and customer data files. High availability was critical as customer’s business is providing a WEB based application service to the insurance industry. Baydel SAStor Solution:- Baydel supplied a single, dual controller Fiber Channel SAStor array fitted with a mixture of disk drives to satisfy the database I/O performance requirements and high capacity needed to store all the data files. The ability to manage the storage remotely was a key requirement as the system was installed in separate secure ISP site.

Customer requirement:- The customer required a storage pool of about 5 Tbytes to be accessed by two Apple Xserves, both running ‘Unix’ and supporting both databases and large graphical data files. High transfer rates from disk to the user was critical as many of the customer’s graphical files were very large. The system was also required to be highly available. Baydel SAStor Solution:- Baydel supplied a single, dual controller Fiber Channel SAStor array fitted with high capacity disks yielding four 1.2 Tbyte logical disks – two on each controller. Apple supplied FC host adapters were used to connect the SAStor. Each Xserve has access to a 1.2 Tbyte logical disk on each controller and mirrors the data to both LUNs. Concurrent, sustained data rates of over 100 Mbytes/s are achieved between the server and clients.
