VMware iSCSI multipathing, redundancy and digital fortress.

VMware iSCSI network storage redundancy is crucial for ensuring data availability and preventing downtime. This involves implementing multiple paths and components to avoid single points of failure, such as redundant network paths, controllers, and even entire storage systems. ✔️ Network Redundancy ➖ Multiple Paths: iSCSI connections should utilize multiple network paths (NICs, cables, switches) to allow for failover in case of a network component failure. ➖ Redundant Switches: Using redundant switches with cross-connections ensures that if one switch fails, the other can take over, maintaining connectivity. ➖ Path Selection: Configuring the path selection policy (e.g., Round Robin) on the storage systems allows for automatic failover to a working path if one fails. ✔️ Storage Redundancy ➖ Dual Controllers: Redundant storage controllers ensure that if one fails, the other can take over, preventing data loss and downtime. RAID: ➖ Implementing RAID (Redundant Array of Independent Disks) on the storage system protects against disk failures and ensures data integrity. Multipathing: ➖ Multipathing software enables the use of multiple paths to access storage, allowing for failover in case one path becomes unavailable. ➖ Redundant Power Supplies: Dual power supplies ensure that a power outage on one source doesn't affect the storage system's operation. ➖ Cooling: Redundant cooling systems prevent overheating and hardware failures. ✔️ Server Redundancy ➖ Clustering: Clustering servers together with shared storage allows for seamless failover if one server goes down. The remaining servers can take over the workload. ➖ Redundant NICs: Using multiple network interface cards (NICs) on servers provides redundancy for network connections to the storage system. ➖ Virtualization: Virtualization platforms like VMware, Hyper-V, and Xen can be used to create virtual machines that can be migrated to other physical servers in case of failure.
