IBM Storage DS 3400 Product is the first entry-level product of the IBM Storage Family to use Fiber Channel Technology.. IBM Storage DS 3400 uses FC technology, Direct Attach and FC SAN Attach technology, and falls into the category of External DAS and SAN technology.
FC – Fiber Channel; The cutting-edge technology of SCSI communication is a serial network interface. By using fiber optic cable and copper wire cable, it communicates with the units over which it has made the connection in the fastest way.. It is a technology that can carry the data between devices to a distance of 10 km and can scale 16 million addresses.. FC technology can carry high bandwidth and data in high confidentiality. As it can carry a data point to point (point to point), it can also be designed with FC SAN Sws.
DS3400’s appearance and physical properties are the same as other IBM DS 3000 Storage family products, and the rear connection modules of the enclosures are seen in the picture above.
Storagemize has two separate Raid Controllers, Single and Dual.. There are two separate Host entry ports on each Controller, Ethernet port to manage and configure our Storage and Raid Controls, Console access port and HOST Expansion SAS port to expand our Storage.

In this design, we can connect two single output Sinle HBA Cards to the same physical server. By installing one, we use the redundancy of our HBA Card and Cable and the Fault torelanca architecture.. Apart from this, we provide acceleration in transfer with the use of Dual Card.. In dual connection, a data is divided into two and written to our storage using two different ways.. Thus, the data communication between our host and our storage will be maximum 8 Gbs/sec.

The above In the design, we can see the most efficient design where we can connect a single host.. By connecting two of our dual-port Dual HBA cards on our host, we connect the cable to our storage on four different links.. Thus, we will be able to get the best results for both fault torelance and performance.

According to our previous structure, our HBAs have been used as Dual instead of Single, and the cable connection between the SAN SW and the Host has been redundantly connected for fault torelance.
What we need to know in this design The most important thing is that our SAN SW comes with 8 Port License. This means that even if we have 16 physical ports on the SAN SW in the above design, we can only use 8 ports of this SW.. In order to use our other 8 ports, we have to purchase SAN SW Port licenses.. SAN SW Port licenses are sold as 4 ports and we will be able to realize our design with the 4 port license we will buy.. With a 4 port license, a total of 12 ports will be available on the SW.
The letter S on the San SW, the numbers 0 and 4 appearing as green ports are designed for Storage connection. On the right side, ports 8 and 16 are designed for storage.. We can connect our HOST (servers) to other ports..
There is one Ethernet management port and Console Port input so that we can manage our SW.

According to our previous structure, the HBA on our Hosts By using our HBAs as Singles, two HBAs are physically used and in addition to the previous structure, fault torelance architecture is considered for our HBAs.. The rule we have mentioned for port license continues to be valid here and in the following plus 8 port usages.

We see one of the healthiest structures built with the Fault Torelance architecture in mind.. If we interpret our design, with Dual SAN SW, the incoming connections over our Storage and Hosts are cross-linked to prevent a possible Cable error between Host and SAN SW.. Storage connection over SW will be connected in the same way, and the life time will not be affected in case of cable failure between SW and Storage.. Over the SW, the connection to the Storage’s Controller is Dual, the connection to each controller is cross-linked and the error on the SW is included in the plan..
The Fault Torelance Architecture at the next level of this design, our HBA cards will be connected as Dual instead of using a single physical HBA as Dual, and thus, a fault that may occur on our HBAs will be backed up. .
In this and similar structures, my recommendation is always to use two physical SAN SWs.. The reason is because the port licenses to be purchased in terms of cost are almost over a third of the value of a physical SAN Sw.. Using two physical SWs with 8 ports activated rather than getting a port license will always favor propagation of the fault for Fault Torelance.

In the design above, we can see a design made without considering any Fault Torelance architecture.
Based on product needs. When it does, we see SW2 according to other needs.. In our previous Storage article, we said that the DS3000 Family allows up to 4 logical Partitions and that we can make up to 16 logical Partitions with the DS3000 Partition Expansion License’ to be purchased.. In the above structure, eight different servers will be connected and we will need to map (connect) these eight servers to different logical drivers.. We will need the DS3000 Partition Expansion License for this connection.. The DS 3000 family allows a maximum of 16 logical partitions, and the DS 4000 family should be considered for more logical partitions.
In the IBM DS 3000 Storage Family, the IBM DS 3400 is the other largest The important feature is that we can back up our data in the storage to Cassette Backup units by connecting our data in the storage to our SAN SW with Fiber Cable (it will definitely not be directly connected to the storage).
