The IBM 1815 expands its DS4000 series midrange disk storage offerings of high-performance, high availability, business critical storage solutions, with the introduction of the IBM TotalStorage DS4800 Midrange Disk System Models 82 and 84.
MODEL ABSTRACT 1815-82A
The IBM 1815 DS4800 Model 82A includes 4GB cache (2GB per controller).
MODEL ABSTRACT 1815-84A
The IBM 1815 DS4800 Model 84A includes 8GB cache (4GB per controller).The IBM TotalStorage DS4800 disk system is designed to provide solutions to address the needs of midrange/departmental storage requirements and deliver high erformance, advanced function, high availability, modular and scalable storage capacity, with SAN attached 4 Gbps Fibre Channel (FC) connectivity, and support for RAID levels 0, 1, 3, 5, and 10 up to over 67 terabytes (TB) physical capacity. The DS4800 is designed to deliver up to a two-fold IOP performance increase over the current DS4500 offering and represents the sixth-generation architecture of the DS4000 series family.
A 4U rack-mountable enclosure houses the DS4800 redundant, dual-active intelligent RAID controllers equipped with sixteen 4 Gbps ports (eight ports per controller), for attachment of host servers and DS4000 Storage Expansion Unit enclosures. The DS4800 attaches up to sixteen DS4000 Storage Expansion Units, supporting configurations up to over 67 TB of FC or Serial Advanced Technology Attachment (SATA) disks or a mix of both types of disk drives by use of the optional DS4800 Fibre Channel/SATA Enclosure Intermix feature.
Advanced DS4000 storage management, copy service options, and optional advanced disaster recovery functions are available for the DS4800, including FlashCopy, VolumeCopy, and Enhanced Remote Mirroring.
The DS4000 Storage Manager platform is also available for the DS4800. This storage management software is designed to help centralize storage management
and simplify partitioning of the DS4000 series storage into as many as 64 virtual servers, and strategically allocate storage capacity to maximize storage space.
IBM TOTALSTORAGE DS4000 FAMILY OF DISK STORAGE SYSTEMS
The IBM TotalStorage DS4000 family of storage products is designed to offer a set of building blocks for Fibre Channel (FC)-based SANs, whether you are just starting or expanding an existing storage network. The DS4000 product family
offers scalable physical storage capacity ranging from 73 GB to over 67 TB to
support your growing storage requirements. DS4000 series systems are designed
to be easy to install and manage using the IBM TotalStorage DS4000 Storage
Manager that is available for every DS4000 Storage system. The IBM
TotalStorage DS4000 family offers various controller models at different performance and price points to help address varying SAN needs.
Multiple DS4000 storage systems can be centrally managed from a common S4000 management console located virtually anywhere within an existing LAN infrastructure. Use the DS4000 advanced copy service functions, such as FlashCopy, VolumeCopy, and Enhanced Remote Mirror to help address data
protection and disaster recovery needs.
DS4000 storage systems offer various options for disk drive attachment. Depending on the particular DS4000 model, you have the choice of using high
performance and highly reliable FC disks with the DS4000 EXP710 Storage
Expansion Units for your mission-critical server production data operations,
or the DS4000 EXP100 Storage Expansion Units with Serial Advanced Technology
Attachment (SATA) disks for small business, data archival, reference data and
near-line applications.
Key potential benefits of the DS4000 family of storage systems include:
o High-availability support - dual processors and many redundant hardware components
o Scalability - from 73 GB to over 67 TB of physical capacity
o Performance - excellent throughput to help address application needs
o Advanced DS4000 functions designed to support business continuance - FlashCopy, VolumeCopy, and Enhanced Remote Mirror
NEWEST DS4000 OFFERING - DS4800 DISK SYSTEM MODEL 82 AND MODEL 84
The DS4800 Model 82 and Model 84 are the newest members of the DS4000 series
storage products designed to offer solutions that address the needs of midrange/departmental storage requirements and deliver high performance with
advanced function and high availability. The DS4800 is designed to deliver up
to double the IOP performance of the current DS4500 offering and is based on
new sixth-generation architecture that provides 4 Gbps FC connectivity
directly to host servers, SAN fabric, disk drive expansion enclosures and has
built-in growth to integrate next-generation 4 Gbps disk drives in the future.
The DS4800 supports attachment of up to 16 DS4000 storage expansion enclosures, resulting in the capability of up to 224 disk drives and enabling
storage configurations of up to over 67 TB of physical capacity.
The DS4800 disk systems come in 4U, rack-mountable enclosures that contain
dual, high-performance RAID controllers. DS4800 Model 84 comes with 8 GB of
cache memory (4 GB per controller) while Model 82 comes equipped with 4 GB cache, (2 GB per controller).
PLEASE NOTE THE FOLLOWING INFORMATION REGARDING DS4800 CACHE MEMORY:
ALTHOUGH THE DS4800 MODEL 82 AND DS4800 MODEL 84 WILL PHYSICALLY COME WITH 4 GB AND 8 GB OF BASE CACHE MEMORY, RESPECTIVELY, FIRMWARE UPGRADE WILL BE REQUIRED TO ENABLE ADDRESSING CACHE MEMORY ABOVE 2 GB (1 GB PER CONTROLLER).
A NO-CHARGE FIRMWARE UPGRADE THAT WILL ENABLE FULL UTILIZATION OF CACHE MEMORY IS CURRENTLY PLANNED TO BE AVAILABLE WITHIN 90 DAYS OF GENERAL AVAILABILITY OF THE DS4800 ON THE DS4000 SUPPORT WEB SITE.
The DS4800 contains eight 4 Gbps FC host ports and eight 4 Gbps FC drive ports. The ports are enabled by populating them with 4 Gbps Small Form-factor Pluggable (SFP) transceivers. Eight shortwave 4 Gbps SFP transceivers are provided in the DS4800 ship group. Depending upon the user's requirements, the supplied SFP transceivers can be used to populate four of the eight host ports (two ports per controller), and four of the eight drive ports (two ports per controller). Up to four, shortwave 4 Gbps SFP transceiver features (#2410) can be ordered for connectivity to all of the host and drive ports.
Each feature #2410 contains two (2) shortwave 4 Gbps SFP transceivers and will
populate two host or two drive ports. Eight DS4000 Storage Expansion Units can be attached using four of eight populated drive ports. For attachment of greater than eight, but less than thirteen supported DS4000 Storage Expansion Units, 6 populated drive ports are required for connectivity. For greater than twelve, up to a maximum of sixteen storage expansion units, 8 populated drive ports are required. The DS4800 can attach either the DS4000 EXP710 FC Storage Expansion Unit (for fibre channel drives), or the DS4000 EXP100 Storage Expansion Unit that houses Serial ATA disk drives. With the optional DS4800 FC/SATA Enclosure Intermix feature #7306, flexibility is provided to concurrently attach drive paths containing both types of storage expansion units up to a combined maximum of 16 expansion enclosures and 224 disk drives.
Key elements of the DS4800 Disk Systems Models 82 and 84 are:
o Dual, high-performance intelligent RAID controller cards, with sixteen 4 Gbps FC ports for host connections and attachment to disk storage expansion units.
o Eight shortwave 4 Gbps SFP transceivers included with ship group to populate user selected host and drive ports.
o Eight 4 Gbps FC host ports (four ports per controller) for connections to SAN fabric, or directly to host servers. Auto-negotiation of 4, 2, or 1 Gbps FC speeds.
o DS4800 Model 82 contains 4 GB of cache (2 GB per controller) with battery backup
o DS4800 Model 84 contains 8 GB of cache (4 GB per controller) with battery backup
o Eight drive-side ports for attachment of up to sixteen DS4000 storage expansion units with a maximum of up to 224 disk drives (up to over 67 TB of physical storage capacity)
o Selectable Storage Partitions of either 8, 16, or 64 partitions
o Support for RAID 0, 1, 3, 5, and 10
o IBM TotalStorage DS4000 Storage Manager V9.14 host-based code support that comes with each optional host kit
o Optional DS4800 FlashCopy, VolumeCopy, and Enhanced Remote Mirroring copy
services and disaster recovery features
o Dual power supplies and redundant cooling fan assemblies
o Attachment to a wide range of industry-standard SAN switches and directors
