The DS has an internal physical storage capacity ds47700 up to 4. Physical storage capacity can be increased up to 84 TB by attachment of up to six DS storage expansion units. They are designed to deliver high performance with advanced function and high availability. These models employ sixth-generation architecture that delivers 4 Gbps FC connectivity directly to host servers, SAN fabric, and disk drive expansion enclosures.
The combination of System p5 and DS Express can help maximize your infrastructure investment. Both ds700 connect to host servers and SAN fabric via host ports and connect to DS storage expansion units via disk drive expansion ports.
You can enable the ports by populating them with 4 Gbps small form-factor pluggable SFP transceivers. Four shortwave 4 Gbps SFP transceivers are included with the model 70 shipment group and six shortwave 4 Gbps SFP transceivers are included with model For the model 70, depending on your requirements, you can use the four supplied SFP transceivers to populate the four host ports two ports per controllerif the configuration does not require DS storage expansion units.
Alternatively, you can use ds470 four SFP transceivers to populate two host ports one port per controller and two disk expansion ds4070 one port per controller.

If you need additional connectivity, you can order up to two shortwave 4 Gbps SFP transceiver features feature for connectivity to all host ss4700 drive ports. Each shortwave SFP transceiver feature feature contains two shortwave 4 Gbps SFP transceivers and populates two host or two drive es4700. For the model 72, depending on your requirements, you can use the six supplied SFP transceivers to populate six of the eight host ports three ports per controllerif the configuration does not require DS storage expansion units.
Alternatively, you can use iibm six SFP transceivers to populate four host ports two ports per controller and two disk expansion ports one port per controller or two host ports and four drive ports. If you need additional connectivity, you ds4070 order up to three shortwave 4 Gbps SFP transceiver imb feature for connectivity to all host and drive ports on the DS Model You can expand storage capacity by attaching DS storage expansion units for configurations up to 84 TB physical storage capacity.
Model 70 enables up to 16 E-DDMs. Key features of the Express models 70 and 72 include: Model 70 contains 2 GB of cache memory 1 GB per controllerfour 4 Gbps FC host ports two sd4700 per controllerand four shortwave SFP transceivers included with the shipment group for connections to SAN fabric or directly to host servers.
Model 72 contains 4 GB of cache memory 2 GB per controllereight 4 Gbps FC host ports four ports per controllerand six shortwave SFP transceivers included with the shipment group for connections to SAN fabric or ds44700 to host servers. Four drive expansion ports two ports per controller for attachment of up to six DS storage expansion units with a maximum of up to E-DDMs up to 84 TB of physical storage capacity.
Model 70 has iibm storage partitions of either 2, 4, 8, 16, or Model 72 has selectable storage partitions of either 8, 16, or Support for RAID 0, 1, 3, 5, and DS Storage Manager V9. Dual power supplies and redundant cooling fan assemblies.
Attachment to a wide range of industry-standard SAN switches and directors. DS storage partitions The DS has advanced storage management and capacity allocation options. For model 70, you can select either 2 feature4 feature8 feature16 featureor 64 feature plant-installed storage partitions.
For model 72, you can select either 8 feature16 featureor 64 feature plant-installed storage partitions. You must select one of these storage partition options during the initial order of the DS You can choose to field upgrade your DS to increase the number of storage partitions up to a ss4700 of 64 at a later date.
DS host kits For attachment to host servers, you must order at least one of the following optional host kit features during initial order of the DS disk system. It offers a common storage management platform for the DS series. The DS Storage Manager gives administrators a powerful, yet easy-to-use management interface.
The flexibility of configuring the DS Storage Manager is designed to enable you to mix drive technologies when intermix is activatedmanage RAID levels, segment sizes, volume group sizes, volume characteristics, and cache policies — all within a single DS storage system. When you activate the optional storage partitioning features, the DS Storage Manager can enable a single DS storage system to function as multiple logical storage systems to meet sd4700 needs of storage consolidation in heterogeneous environments.
