They may vary depending on the size of the stack. For example to connect the zero switch to the upper one you nee a longer cable than for the link between the first and second devices. In addition stack cables are thick and difficult to squeeze into racks. Stack rear view. Source The second and third options are deprive of these problems at the design stage. No nee to keep stack cables in spare parts. You can use conventional transceivers and optical patch cords which are neee to include client links in switches.
Computing Power After Peak Loads
Moreover you can place devices at a distance of more than meters. This is useful when you nee to locate switches at different points in the data center. Complicate software update process on switches You cannot upgrade just one switch. You nee to update on all devices. Stacking one might say does not tolerate switches with different software Bahamas Email List versions. However in models of some vendors the update process is optimize. For example on Cisco switches each of the devices is update in turn and goes into reboot. That is there are switches that continue to serve customers. A similar technology is implemente by Juniper but there are vendors or models where all switches in the stack are reboote simultaneously. High probability split brain Imagine that the stack consists of two switches.
The Qualifications Of Administrators Must
Between them stretche stack cables. In case of damage to the port or link a situation may arise the first switch considers that the second has fallen and the second switch that the first has fallen. Both of them work though. Because of this an extra stack master BM Leads appears and everything starts to fail. To get rid of all the disadvantages networkers came up with MLAG. What is MLAG and why is it better than Stack MLAG MC LAG Multi Chassis Link Aggregation is a technology for combining the data plane of several switches into one logical data plane but maintaining a separate control plane on each of the switches. Like Stack the technology is proprietary you cannot create pairs of switches from different vendors. Reundant MLAG Connection Source MLAG technology may be known by various names.
