Page 52: Daisy-Chain Jbod Enclosures
The NexStor 4000F JBOD enclosure is used as the daisy-chain enclosures to expand the number of drives available to the NexStor 4900F Series Storage Systems up to the limit of 96 disk drives. The JBOD enclosure is conﬁgured as a Single Bus Dual-Loop system, where the drive plane is a continuous 12 (twelve) drive single bus dual-loop FC-AL conﬁguration.
Page 53: San Lun Mapping
Chapter 2 - Topologies and Operating Modes SAN LUN Mapping The RAID Controller has extensive support for SAN LUN Mapping (SLAM). A logical drive (LUN) can be mapped to particular host HBA or to a particular host HBA port. Up to 512 logical drive mappings can be created, with a 2 TB per logical drive limitation.
Page 54: Alternate Path Software
Chapter 2 - Topologies and Operating Modes Alternate Path Software This is a software tool that manages multiple paths between the host operating system and LUNs (logical drive). The software manages the multiple paths by detecting duplicate disk objects that represent a single logical drive. It then designates one disk object as the primary disk object with a primary path, while the other is designated the secondary disk object with an alternate path.
Page 55: A Word About Clustering
Chapter 2 - Topologies and Operating Modes A Word about Clustering Minimizing Downtime for Maximum Data Availability So-called open systems, such as Windows servers, just don’t provide the level of availability that IS managers are familiar with on mainframes. A partial solution to this problem is server clustering.
Page 56 Chapter 2 - Topologies and Operating Modes High availability is not the only beneﬁt of clustering. In some cases, users may see advantages in the areas of performance, scalability, and manageability. In reality, you can expect a 1.6x (80% efﬁciency) to 1.8x (90% efﬁciency) performance increase as you go from one node to two nodes.
