Overview:
IBM Storage Networking SAN42B-R7 is an extension class SAN switch with up to 24 Fibre Channel ports at 64 Gbps. It is part of IBM’s range of storage area network extension switch hardware.
IBM Storage Networking SAN42B-R7 is designed to bridge the gap between geographically dispersed data centers to enable fast, continuous, and secure replication of mission-critical data with strong AES 256-bit hardware encryption to prevent data loss or data breaches when in-flight across the WAN.
Highlights
- Deploy cyber-resilient replication connectivity for enterprise storage
- Replicate data between data centers using purpose-built solutions
- Move more data more quickly over greater distances
- Protect data from WAN disruptions and outages
- Safeguard data from threats over the WAN
Features:
Extension trunking
Combines multiple WAN connections into a single, logical, high-bandwidth trunk, providing active load balancing and network resilience to protect against WAN link failures.
Lossless Link Loss (LLL)
Part of Extension Trunking, provides recovery of data lost in-flight when a link goes offline. From the perspective of the storage applications, nothing ever occurred because all data is delivered, and is delivered in order.
Failover/failback with failover groups
Circuits are assigned metrics and put in a failover group. If all circuits of the lower metric within the failover group go offline, the higher metric circuits take over. The storage application will not know that a failover/failback has occurred.
Adaptive Rate Limiting (ARL)
Dynamically adjusts bandwidth sharing between minimum and maximum rate limits to optimize bandwidth utilization and maintain maximum WAN performance during disruptions.
IPsec encryption, real-time alerts
Ensures secure transport of data over WAN links at full line rate. Security is turned on without a performance penalty or excessive added latency. With a hardware-implemented, standard 256-bit AES algorithm, data-in-flight is encrypted.
WAN-optimized TCP
An aggressive TCP stack, optimizing TCP window size and flow control and accelerating TCP transport for high-throughput storage applications.
Advanced compression architecture
Provides multiple modes to optimize compression ratios for various throughput requirements.
FCIP FastWrite
Accelerates SCSI write processing, maximizing performance of synchronous and asynchronous replication applications across high-latency WAN connections over any distance.
Open Systems Tape Pipelining
Accelerates read and write tape processing over distance, significantly reducing backup and recovery times.
Benefits:
Optimize data replication
Leverage high speed connectivity with 64G FC/FICON ports and 100/25/10/1Gb Ethernet/WAN ports to optimize recovery objectives for fast and reliable data transfer while minimizing latency and packet loss over long distances.
Protect data from disruptions
Protect against WAN link failures with extension trunking which switches data traffic to alternate links in the event of failure to maintain uninterrupted data transfer while adaptive rate limiting (ARL) and TCP flow optimization help allocate bandwidth and mitigate the risk of disruptions.
Move more data, faster, over distance
Accelerate data movement with high throughput, high-efficiency encapsulation of FCIP and WAN-optimized TCP to move data over long distances in less time. In addition, FCIP FastWrite accelerates write processing to maximize performance and reduce latency.
Safeguard data from threats over the WAN
Leverage the built-in security of the IBM SANnav management portal to configure and customize security thresholds and access. SSL certificates and security protocols prevent data tampering. A robust hardware-based IPsec with 256-bit AES algorithm helps protect data during transmission and meet compliance.
