Introducing the IBM System Storage DS3524 DC and EXP3524 DC
The IBM System Storage DS3524 Express DC Storage System and EXP3524 Express DC Expansion Unit are the newest addition to the IBM System Storage DS3500 family of entry disk storage systems. The DS3500 series delivers affordable, entry-level configurations for small and medium businesses in compact 2U, 19-inch rack mount enclosures, with the flexibility to scale in capacity, performance, host interfaces, and advanced functions as your business grows or requirements change.
The DS3524 DC and EXP3524 DC are designed specifically for the telecommunications industry and service providers. These new models are designed to support the same functional capabilities as the DS3500 ac-powered models, but are powered from an industry-standard -48 V dc power source. They also conform to applicable NEBS level 3 documents and to applicable ETSI documents.
The previously announced DS3500 and EXP3500 ac-powered models now also conform to applicable NEBS level 3 and ETSI documents.
New technology delivers new levels of performance
The DS3524 DC combines next-generation controller technology with the latest, high-performance host interface technologies to deliver new levels of performance compared to the IBM System Storage DS3000 series.
The DS3524 DC with its dual-active controllers is designed to be equally adept at delivering throughput to bandwidth-intensive applications and I/O operations to transactional applications, such as databases and Microsoft® Exchange. This balanced performance, combined with the ability to handle concurrent workloads, makes the DS3524 DC a great fit for consolidation and virtualization environments.
The performance of the system can be further enhanced with the Turbo Performance option, which is available with the initial purchase of your system or as an upgrade to an existing system.
Latest host interface technologies with intermix flexibility
The DS3524 DC supports the latest host interface technologies, 6 Gb per second SAS and 8 Gb per second Fibre Channel. Along with 1 Gb per second iSCSI support and the capability to intermix host interface technologies, the DS3524 DC addresses shared storage requirements within a single system.
- Second-generation, 6 Gb SAS builds upon the solid foundation of 3 Gb SAS with performance improvements and reliability enhancements. With direct attachment support and the capability to be shared by multiple host servers, the DS3524 DC with SAS provides ease-of-use and simplicity at an affordable price.
- Fibre Channel, a mature and proven technology now available at 8 Gb, is the host interface of choice for high-performance environments. The DS3524 DC with Fibre Channel allows you to exploit the benefits offered by a SAN environment.
- iSCSI allows you to capitalize your existing IT skills and infrastructure by delivering block-based storage across the IP network. The DS3524 DC with iSCSI provides an alternative to direct attach SAS or the investment in a storage-only, Fibre Channel infrastructure.
SAS host interface ports are standard on the DS3524 DC. Optional additional SAS ports, FC ports, or iSCSI ports can be added. The following configurations are available:
6 Gb 8 Gb 1 Gb SAS FC iSCSI Ports Ports Ports 4 -- -- 8 -- -- 4 8 -- 4 -- 8
Tiered storage options with high performance and nearline SAS disk drives
With support for mixed disk drives within a single system, the DS3524 DC is designed to support a complete range of data storage requirements, from highly utilized applications to high-capacity, low usage applications.
The DS3524 DC and EXP3524 DC support the following dual-port, hot-swappable 2.5-inch 6 Gb SAS disk drives:
- High-performance, enterprise class drives
- 146 GB 15,000 rpm
- 300 GB and 600 GB 10,000 rpm
- High-capacity, archival-class nearline drives
- 500 GB 7,200 rpm
- Self-encrypting drives (SED) for data security
- 300 GB 10,000 rpm
Up to 96 disk drives are supported by a single DS3524 DC storage system with attachment of EXP3524 DC expansion units. Additional disk drives and expansion units are designed to be dynamically added with virtually no downtime, helping you to quickly and seamlessly respond to your ever-growing capacity demands.
Energy saving implementations for cost savings today and tomorrow
DS3524 DC was developed with the following energy savings features to reduce power consumption and provide a lower overall total cost of ownership:
- High-efficiency power supplies to meet power efficiency standards for reduced power consumption
- Small form factor (2.5-inch) disk drives which deliver comparable I/O performance when compared to 3.5-inch disk drives, but require less space and consume less power
And the DS3524 DC controller technology creates performance value by getting the most performance out of the fewest disk drives. This reduces the number of disk drives needed to meet performance and capacity demands, resulting in lower acquisition and operational expenditures.
High availability with new data protection and security options
DS3524 DC supports high system and data availability with:
- Dual-active, intelligent array controllers with mirrored cache
- Dual port disk drives with automatic disk drive failure detection and rebuild with global hot spares
- Redundant hardware, including dc power supplies and fans
- Hot-swappable and customer replaceable components
- Automated path failover support for the data path between the server and the disk drives
DS3524 DC supports data protection with:
- RAID levels 0, 1, 3, 5, 6, and 10 provide the flexibility to choose the level of protection required.
- Storage Partitions that logically divide a single DS3500 into multiple systems to manage volume-to-host access.
- FlashCopy and Volume Copy to create logical or physical copies of data for file restoration and backup
- Remote Mirroring to provide storage system-based data replication from one system to another system using either synchronous or asynchronous data transfers over Fibre Channel communication links.
- Full Disk Encryption (FDE) provides local key management and disk drive-level encryption for comprehensive data security and protection. DS3524 DC locally manages and protects the self-encrypting drives (SED) by utilizing a single authorization scheme (or lock key) that can be set and applied to all SED drives within a system. DS Storage Manager maintains and controls the key linkage and communications with the SED drives, secures user-selected logical drive groups, and can even initiate an instant secure erase feature when servicing, decommissioning, or repurposing drives. The DS3524 DC FDE engine performs encryption without a performance penalty, which allows you to achieve new levels of data security without sacrificing performance. With these encryption services, FDE key management is transparent to day-to-day storage administration, making SED drives as easy to manage as traditional drives.
Intuitive storage management with the IBM DS Storage Manager
DS Storage Manager provides a powerful, yet easy-to-use and intuitive graphical user interface (GUI) for DS3524 DC administrative activities, including configuration, reconfiguration, expansion, and routine maintenance, as well as performance tuning and management of advanced functions, such as data replication and Full Disk Encryption (FDE) keys. DS Storage Manager extends the robustness and functionality of storage management previously only available on the DS4000™ and DS5000 products to the DS3500 family, while maintaining the ease-of-use and intuitive nature of the DS3000 Storage Manager. It provides a complete physical view of your system, but with expertise built into the interface and automated policy decisions, you no longer have to contend with low-level activities.
Rich set of data replication functions for business continuity
FlashCopy creates a capacity-efficient, point-in-time copy of a physical volume for data protection uses, such as file restoration and backup. A FlashCopy volume is the logical equivalent of the physical volume, but is created more quickly than a physical copy and with minimal disruption to applications and production processes. Using copy-on-write technology, FlashCopy volumes preserve data in its original form even as data in the physical (source) volume is changed. FlashCopy volumes appear and function as standard storage volumes, and restoration of a FlashCopy volume is quick and easy.
Volume Copy creates a physical copy of a volume. Volume Copy is used with FlashCopy to create a physical copy of your data with minimal disruption to applications and production processes. Upon completion of the Volume Copy process, the new volume can be mapped to any host and functions as a standard volume. Volume Copy can also be used to redistribute data within the system, moving volumes to a different disk drive technology or RAID level.
Both FlashCopy and Volume Copy are performed by DS3524 DC storage system, so no host server resources are used.
Remote Mirroring provides storage system-based data replication from one DS33534 DC system to another DS3500 system over Fibre Channel communications links. Remote Mirroring supports synchronous or asynchronous data transfers, enabling you to choose the replication method that best meets your protection, distance, or performance requirements:
- Synchronous mirroring is designed to provide continuous mirroring between primary and remote volumes to help ensure absolute synchronization.
- Asynchronous mirroring queues remote writes to reduce the latency, thus enabling long distance replication while increasing local system performance. Asynchronous mirroring includes a write consistency option designed to ensure that writes to the remote system complete in the same order as the local system.
Remote Mirroring also includes features such as dynamic mode switching, suspend and resume with delta resynchronization, read-only and FlashCopy / Volume Copy access to secondary volumes, and cross-mirroring.

These services are designed to provide the opportunity for greater system availability with faster problem resolution and preemptive monitoring. Electronic Services comprises two separate, but complementary, elements: Electronic Services news page and Electronic Services Agent.
The Electronic Services news page is a single Internet entry point that replaces the multiple entry points traditionally used to access IBM Internet services and support. The news page enables you to gain easier access to IBM resources for assistance in resolving technical problems.
The Electronic Service Agent™ is no-additional-charge software that resides on your server. It monitors events and transmits system inventory information to IBM on a periodic, client-defined timetable. The Electronic Service Agent automatically reports hardware problems to IBM. Early knowledge about potential problems enables IBM to deliver proactive service that may result in higher system availability and performance. In addition, information collected through the Service Agent is made available to IBM service support representatives when they help answer your questions or diagnose problems. Installation and use of IBM Electronic Service Agent for problem reporting enables IBM to provide better support and service for your IBM server.

Warranty period and warranty service
Warranty period
- System (including the cache backup battery module): Three years
- Optional features: Three years, unless specified otherwise
An IBM part or feature installed during the initial installation of an IBM machine is subject to a full warranty effective on the date of installation of the machine. An IBM part or feature which replaces a previously installed part or feature assumes the remainder of the warranty period for the replaced part or feature. An IBM part or feature added to a machine without replacing a previously installed part or feature is subject to a full warranty effective on its date of installation. Unless specified otherwise, the warranty period, type of warranty service, and service level of a part or feature is the same as the machine it is installed.
Warranty service
Customer Replaceable Unit (CRU) and On-Site Service
If required, IBM provides repair or exchange service depending on the types of warranty service specified for the machine. IBM will attempt to resolve your problem over the telephone, or electronically via an IBM website. Certain Machines contain remote support capabilities for direct problem reporting, remote problem determination, and resolution with IBM. You must follow the problem determination and resolution procedures that IBM specifies. Following problem determination, if IBM determines on-site service is required, scheduling of service will depend upon the time of your call, machine technology and redundancy, and availability of parts. If applicable to your product, parts considered Customer Replaceable Units (CRUs) will be provided as part of the machine's standard warranty service.
Service levels are response-time objectives and are not guaranteed. The specified level of warranty service may not be available in all worldwide locations. Additional charges may apply outside IBM's normal service area. Contact your local IBM representative or your reseller for country and location-specific information.
CRU Service
IBM provides replacement CRUs to you for you to install. CRU information and replacement instructions are shipped with your machine and are available from IBM upon your request. CRUs are designated as being either a Tier 1 (mandatory) or a Tier 2 (optional) CRU.
Tier 1 (mandatory) CRU
Installation of Tier 1 CRUs, as specified in this announcement, is your responsibility. If IBM installs a Tier 1 CRU at your request, you will be charged for the installation.
Tier 2 (optional) CRU
You may install a Tier 2 CRU yourself or request IBM to install it, at no additional charge.
Based upon availability, CRUs will be shipped for next-business day (NBD) delivery. IBM specifies, in the materials shipped with a replacement CRU, whether a defective CRU must be returned to IBM. When return is required, return instructions and a container are shipped with the replacement CRU. You may be charged for the replacement CRU if IBM does not receive the defective CRU within 15 days of your receipt of the replacement.
The following parts have been designated as Tier 1 CRUs:
Bezel Cache Cache backup battery module Controller Disk drive Filler panel I/O adapter I/O cable I/O transceiver Power supply unit Rack kit Services module
CRU and On-site Service
At IBM's discretion, you will receive specified CRU service, or IBM will repair the failing machine at your location and verify its operation. You must provide a suitable working area to allow disassembly and reassembly of the IBM machine. The area must be clean, well lit, and suitable for the purpose.
Service level is:
- 9 hours per day, Monday through Friday, excluding holidays, next business day response. Calls must be received by 5 p.m. local time in order to qualify for next business day response.
International Warranty Service
International Warranty Service (IWS) is available in selected countries or regions.
The warranty service type and the service level provided in the servicing country may be different from that provided in the country in which the machine was purchased.
Under IWS, warranty service will be provided with the prevailing warranty service type and service level available for the IWS-eligible machine type in the servicing country, and the warranty period observed will be that of the country in which the machine was purchased.
To determine the eligibility of your machine and to view a list of countries where service is available, visit
For more information on IWS, refer to Services Announcement 601-034, dated September 25, 2001.
