This SAN (Storage Area Network) Storage Buying Guide provides a detailed review of
Fibre Channel (FC), Fibre Channel over Ethernet (FCoE) and iSCSI SAN block storage arrays, which includes features and performance to help guide your storage purchase decisions. Better SAN storage acquisition should boost application performance, increase end-user satisfaction and enhance IT ROI.
We expect that new CIOs, IT architects and storage admins will use this guide to learn about vendor offerings, functionality and storage performance to better understand what to look for when selecting SAN storage systems. Moreover, from our buying guide experienced CIOs, IT architects and storage admins should be able to easily understand new storage features and functionality and gain a better appreciation of how current storage systems perform under various application environments.
We discuss storage hardware capabilities such as all flash arrays and hybrid storage characteristics, front end/backend protocols and other attributes, as well as block storage functionality including data protection, storage virtualization, scale-up/scale-out, snapshot copies, thin provisioning, date deduplication & compression, remote replication/mirroring, and other advanced capabilities of current SAN storage products.
We also describe some alternatives to traditional, on premises storage appliances such as software defined storage, cloud storage gateways and new Tier 0 storage.
In addition, we provide the latest performance champions for current storage systems under OLTP, Email and throughput intensive application environments. We report our performance results separated by the class of storage to identify storage champions for
Enterprise, Mid-range and SMB systems for these workloads. Given the performance advantages of flash storage, we also cover all-flash array storage system performance results separately, where applicable.
