The IBM 2105 ESS Model 800, the third generation of IBM intelligent storage, integrates a new generation of hardware, including faster symmetrical multi-processors (SMP) with an optional Turbo feature, 64 GB cache, double internal bandwidth, and 2Gb Fibre Channel/FICON host adapters. This hardware, in addition to RAID 10 support and 15,000 rpm drives, enables the Model 800 to deliver excellent levels of performance and throughput.
Only previously installed, refurbished ESS Model 800 machines are available. The refurbished Model 800 supports the same features and functions as the Model 800, with the exception of the ESS Standby Capacity on Demand offering. These refurbished machines include a three-year warranty and are offered on an as-available basis. The special bid process must be used by IBM representatives and IBM Business Partners to obtain availability and pricing information, and feature number 9940 (Refurbish Product Indicator) is required when placing an order for a refurbished Model 800.
The ESS Model 800 - The Third Generation of IBM Intelligent Storage
The ESS Model 800 is the third generation of the ESS and builds upon the functionality, stability, reliability, and proven track record of the earlier models.
The Model 800 integrates a new generation of hardware, including a standard processor (with an optional Turbo and Turbo II feature), 64 GB cache, 2 GB Non Volatile Storage (NVS), increased internal bandwidth, and 2Gb Fibre Channel/FICON Host Adapters. This hardware, when combined with RAID 10 support and 15,000 rpm drives, enables the Model 800 to deliver excellent levels of performance and throughput.
The Model 800 supports up to 55.9 TB of physical capacity that can be configured as RAID 5, RAID 10, or a combination of both. RAID 5 remains a price/performance leader, offering excellent performance for most customer applications, while RAID 10 can offer better performance for selected applications. Price, performance, and capacity can further be optimized to meet specific application and business requirements through the intermix of 18.2, 36.4, 72.8, and 145.6 GB drives operating at 10,000 or 15,000 rpm.
Yet with all this, the fundamental design of the ESS remains unchanged. The Model 800 supports 24 x 7 operations with a design that avoids single points of failure by providing component redundancy. The Model 800 also maintains the advanced functions that deliver business continuance solutions (FlashCopy, FlashCopy Version 2, PPRC, PPRC Version 2, PPRC Extended Distance, and XRC), as well as FICON, Parallel Access Volumes (PAV), multiple allegiance, and I/O priority queuing to offer great performance in the zSeries and S/390 environments.
15,000 rpm Drives Offer Additional Levels of Throughput and Perforance
The 15,000 rpm drives, which are available in 18.2, 36.4, and 72.8 GB capacities, offer levels of throughput and performance that can translate into price/performance benefits for the entire system.
- An ESS populated with eight RAID 5 ranks of 18.2 or 36.4 GB, 15,000 rpm drives can provide up to 80% greater total system random throughput for a cache standard workload than a comparably configured ESS with 10,000 rpm drives.
- The 72.8 GB, 15,000 rpm drives can provide up to 20% greater random throughput than a comparably configured ESS with 10,000 rpm drives.
- An ESS populated with eight RAID 5 ranks of 72.8 GB, 15,000 rpm drives can provide up to 25% better service time for a cache standard workload than a similarly configured ESS with comparable capacity consisting of 16 ranks of 36 GB, 10,000 rpm drives.
These drives can help you drive your workloads at significantly higher access densities (without performance degradation) and fewer disk drives may be required to achieve high disk utilization rates, which can lead to cost savings. Reduced response times may also be realized, providing shorter batch processing windows or improved productivity because transactions complete more quickly.
Extensive Connectivity with 2Gb Fibre Channel/FICON Support For Higher Performance SANs
The Model 800 follows in the footsteps of the earlier ESS models with extensive connectivity support -- including Fibre Channel, FICON, ESCON, SCSI, iSCSI, and NAS -- across a broad range of server environments -- including zSeries and S/390, pSeries and RS/6000, iSeries and AS/400, xSeries and other Intel-based servers, Sun, Hewlett-Packard, and Compaq AlphaServer. This rich support of heterogeneous environments and attachments, along with the flexibility to easily partition the ESS storage capacity among the attached environments in any combination using the IBM TotalStorage Enterprise Storage Server Specialist (ESS Specialist), helps support storage consolidation requirements and dynamic, changing environments.
The Model 800 further enhances this broad set of connectivity options with support for 2Gb Fibre Channel and FICON. The 2Gb Fibre Channel/FICON Host Adapters, which are offered in long-wave and short-wave, auto-negotiate to either 2Gb or 1Gb link speeds. The flexibility enables immediate exploitation of the benefits offered by higher performance, 2Gb SAN-based solutions, while also maintaining compatibility with existing 1Gb infrastructures. As 2Gb capability on servers and fabric components is introduced into existing SANs, your investment in ESS fibre adapters is protected and migration is simplified.
IBM TotalStorage Resiliency Family
The IBM Total Storage Resiliency Family is comprised of IBM TotalStorage Resiliency Core Technology, an extensive set of hardware and software features and products, and IBM TotalStorage Resiliency Automation, integrated software and services packages. The IBM TotalStorage Resiliency Family is designed to help you implement storage infrastructures to help keep your business running 24 hours a day, 7 days a week.
The following ESS Model 800 functions are key components of the IBM TotalStorage Resiliency Core Technology:
- PPRC Metro Mirror (Synchronous PPRC)
- PPRC Global Mirror (Asynchronous PPRC)
- PPRC Metro/Global Copy (Asynchronous Cascading PPRC)
- PPRC Global Copy (PPRC Extended Distance)
- Extended Remote Copy (XRC)
- zSeries Global Mirror (XRC)
- zSeries Metro/Global Mirror (three-site solution using Synchronous PPRC and XRC)
FlashCopy: FlashCopy is designed to provide a point-in-time copy capability for logical volumes. FlashCopy creates a physical point-in-time copy of the data, with minimal interruption to applications, and makes it possible to access both the source and target copies immediately. FlashCopy is an optional feature for the ESS (feature numbers 83xx).
FlashCopy Version 2 further supports business continuance solutions with the following additional functions:
- Data Set FlashCopy
- Multiple Relationship FlashCopy
- Incremental FlashCopy
- FlashCopy to a PPRC primary
- Additional enhancements:
- Elimination of the Logical Subsystem (LSS) constraint
- Establish time improvement
- Consistency group commands
- Inband commands over PPRC link
