Ports and host connections
The DS3500 controller has several connection ports for different purposes (Figure 6). It supports three different host interface cards (HIC), also known as daughter cards, for host connections:
Each of these is shown in the following figures.
Note: Only one type of optional interface can be added to any one DS3500 storage server. Mixing host interface cards between controllers in the same DS3500 is not supported.
Figure 4 shows the connections of a controller without a HIC installed.
Figure 4. DS3500 controller rear view
Figure 5 shows a rear view of the DS3500 with a SAS daughter card installed. Adding the SAS host interface card simply adds two more SAS 2.0 6 Gbps host ports.
Figure 5. DS3500 controller rear view with SAS daughter card
Figure 6 shows a rear view of the DS3500 with a iSCSI daughter card installed. It is essentially just the base controller with four additional RJ-45 Ethernet ports, all usable for iSCSI traffic.
Figure 6. DS3500 controller rear view with iSCSI daughter card
Figure 7 shows a rear view of the DS3500 with a FC HIC installed, which adds four FC 8 Gbps connections, which can also negotiate at 4 Gbps or 2 Gbps.
Figure 7. DS3500 controller rear view with FC daughter card
Each DS3500 and EXP3500 enclosure comes with two high-efficiency, removable, 585-watt power supplies (Figure 8) as standard. Each power supply has two internal fans for cooling the enclosure. The four fans pull air through the drives from front to back across the drives. The DS3500 meets the Network Equipment Building System (NEBS) and European Telecommunications Standards Institute (ETSI) Telco specification requiring very robust abilities and support for 48 V DC power supplies.
Figure 8. DS3500 power supplies/LED indicators
Fiber Channel cables and connectors
In this section, we discuss essential characteristics of fiber cables and connectors. This information can help you understand the options that you have for connecting and cabling the DS3500 Storage System.
Fiber cables are basically available in multi-mode fiber (MMF) or single-mode fiber (SMF). MMF allows light to disperse in the fiber so that it takes many paths, bouncing off the edge of the fiber repeatedly to finally get to the other end (multi-mode means multiple paths for the light). The light taking these various paths gets to the other end of the cable at slightly separate times (separate paths, separate distances, and separate times). The receiver has to determine which in-coming signals go together.
SMF is so thin (9 microns) that the light can barely “squeeze” through and it tunnels through the center of the fiber using only one path (or mode). This behavior can be explained (although not simply) through the laws of optics and physics. The result is that because there is only one path that the light takes to the receiver, there is no “dispersion confusion” at the receiver. Table 8 lists the supported distances.
Table 8. Cable type overview
|Fiber Type||Speed||Maximum distance|
|9 micron SMF (longwave)||1 Gbps||10 km|
|9 micron SMF (longwave)||2 Gbps||2 km|
|50 micron MMF (shortwave)||1 Gbps||500 m|
|50 micron MMF (shortwave)||2 Gbps||300 m|
|50 micron MMF (shortwave)||4 Gbps||150 m|
|50 micron MMF (shortwave)||8 Gbps||50 m|
|62.5 micron MMF (shortwave)||1 Gbps||300 m|
|62.5 micron MMF (shortwave)||2 Gbps||150 m|
|62.5 micron MMF (shortwave)||4 Gbps||70 m|
|62.5 micron MMF (shortwave)||8 Gbps||21 m|
Other feature highlights
This section highlights important features of DS3500 System Storage.
IBM System Storage DS3500 enables Multi-protocol providing concurrent iSCSI/SAS or FC/SAS host connectivity. Figure 9 shows the two available options.
Figure 9. iSCSi/SAS or FC/SAS host connectivity
IBM System Storage DS Storage Manager
The IBM Storage System DS3500 uses the same IBM DS Storage manager as the DS5000 product line and the legacy DS3000 models. Through this software, it is possible to perform administrative tasks such as creating arrays, logical drives, assigning logical drives to the host servers, setting up FlashCopy and Volume Copy, capturing logs for troubleshooting, and so on. Figure 10 shows the IBM System Storage DS Storage Manager Enterprise Management window.
Figure 10. Enterprise Management GUI
The Turbo Key is an optional premium feature that, when enabled, boosts the performance of a storage system across both throughput and IOP workloads, allowing you to take full advantage of DS3500 performance capabilities with bandwidth-intensive applications. The DS3500 Turbo Key offers:
- Scalability to midrange performance and features starting at entry-level prices
- Efficiencies to help reduce annual energy expenditures and environmental footprint
- Simplicity that does not sacrifice control with the perfect combination of robustness and ease of use
Figure 11 provides a comparison with and without the Turbo Key premium feature enabled.
Figure 11. Turbo Key
Storage partitioning adds a high level of flexibility to the DS3500 Storage System. The DS3500 comes with four partitions by default, which can be expanded to a maximum of 128.
It enables you to connect multiple and heterogeneous host systems to the same storage server, in either stand-alone or clustered mode. The term storage partitioning is somewhat misleading because it actually represents a host or a group of hosts and the logical drives that they access. Without storage partitioning, the logical drives configured on a DS3500 Storage System can only be accessed by a single host system or by a single cluster, which can lead to inefficient use of storage server hardware unless the use of the DS3500 Storage System is dedicated to a single host (for example, SVC or v7000 attachment).
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.
With the new FlashCopy Scheduler, its now possible to schedule FlashCopy images via the user interface. This can be applied to new and existing snapshot volumes. Figure 12 and Figure 13 show the new menu item from the GUI interface.
Figure 12. Create Schedule option via GUI Interface
Figure 13. Simple and effective menu for scheduling a FlashCopy Image
The Volume Copy premium feature 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 it functions as a standard volume. Volume Copy can also be used to redistribute data within the DS3500, moving volumes to a different disk drive technology or RAID level. Both FlashCopy and Volume Copy are performed by the DS3500 storage system, so no host server resources are used. A copy can be initiated while the source volume remains available for writes. Figure 14 shows Volume Copy in action.
Figure 14. Volume manager copying from logical drive RootBoot-Blade1 to RootBoot-Blade2
Graphical performance monitor
The graphical performance monitor provides information about storage I/O from multiple view points. This monitoring tool is very important for performance analysis of a managed storage subsystem. It allows administrator to make informed decisions about storage system adjustments, such as free space usage, locating stranded storage, and efficient provisioning. Figure 15 shows the graphical performance monitor feature in the GUI.
Figure 15. Graphical performance monitor
Full data encryption (FDE)
The SAS SED drives are required to enable disk security and can perform symmetric encryption and decryption of data at full disk speed with no impact on performance. The disk encryption hardware is used in conjunction with IBM Disk Encryption Storage Manager on the DS3500 storage subsystem. It uses asymmetric encryption to encrypt and decrypt the data key. IBM Disk Encryption Storage Manager will generate encryption and decryption keys that are used to lock each SAS SED drive.
Figure 16. DS3500 disk encryption manager using self-encrypting SAS SED drives
Remote mirroring provides storage-system-based data replication from one DS3500 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.
IBM RSM for Storage
IBM Remote Support Manager for Storage (RSM for Storage) software is a no-charge software package that is installed on an IBM System x server running Novell SUSE Linux Enterprise Server 9, SUSE Linux Enterprise Server 10, Red Hat Enterprise Linux 4 Advanced Server, or Red Hat Enterprise Linux 5. It provides problem reporting and remote access for IBM Service for the IBM System Storage DS3000, DS4000, and DS5000 families.
The problem reporting utility provided by RSM for Storage automatically creates an entry in the IBM call management system for each subsystem that reports a problem. This is the equivalent of placing a voice call to IBM Service for a problem. Once in the system, problems are responded to with the priority specified by the maintenance agreement in place for the product.

This section describes the requirements and best practice guidelines for connecting EXP3500 enclosures to a DS3500 storage subsystem.
Figure 18 shows the SAS connections between a single controller DS3500 subsystem and three EXP3500 enclosures, with a single ESM installed in each EXP3500. This configuration is a fully functional configuration, but there is no redundancy on the drive-side connections.
Figure 18. Single controller attachment
Figure 19 shows how to correctly cable a dual controller DS3500 to a single EXP3500 enclosure with two ESMs installed. This configuration provides redundancy on the drive-side connections.
Figure 19. Dual controller attachment
Figure 20 shows the SAS cable connections when using the top-down/bottom-up cabling layout with the DS3500 storage subsystem at the top. This is the preferred SAS expansion cabling for when you are connecting two or more EXP3500 enclosures, up to the supported maximum of eight EXP3500 enclosures.
Figure 20. Top-down/bottom-up SAS drive-side connections
This section outlines the supported topologies for a DS3500 considering FC, iSCSI, and SAS connections. There are examples for both single and dual controller DS3500 storage subsystems.
- General rule: Although some of the examples shown next are valid supported configurations, there are some with no redundancy of host-side connections. Always use redundant host-side connections instead.
- FC direct attachment: The DS3500 storage subsystem supports both direct attached and SAN fabric attached hosts. You can attach up to four direct-connected hosts or up to 64 host servers in a switched fabric SAN infrastructure. This section describes sample configurations of direct-attached Fibre Channel host servers.
- SAS connections: Host server SAS HBAs are used to connect to the DS3500 SAS ports. Each DS3500 controller can have up to four SAS host ports when you install the optional SAS host interface adapter. When the optional SAS host interface adapter is installed, the DS3500 can support up to 28 Blade Center hosts when attached to the SAS Connectivity Module for IBM Blade Center and up to four hosts in a direct attached host environment.
The DS3500 supports multiple-host, multiple-port, and multiple-fabric (Fibre Channel or iSCSI, and SAS) configurations. That is, the DS3500 storage subsystem supports simultaneous SAS and either iSCSI or Fibre Channel host connections with the optional iSCSI or Fibre Channel host adapter installed, up to a maximum of 64 hosts. Figure 21 shows an example of this type of configuration with one SAS attachment and one iSCSI or FC host.
Figure 21. Host connections
Warranty period and warranty service
Every DS3500 is covered by the below warranty:
- System (including the cache backup battery module): three years
- Optional features: three years, unless specified otherwise
