Common Mistakes to Avoid
Several recurring pitfalls show up across SAN-related tool choices when requirements and operational models are mismatched.
Buying a management-only tool when a storage target is required
Hanewin Server focuses on SNMP-driven monitoring and topology-aware discovery for SAN devices and fabric components rather than providing an iSCSI target or array LUN services. Teams that need actual SAN block presentation should use Open iSCSI Target (Linux LIO), TrueNAS SAN iSCSI, or Dell PowerVault ME4 Series Storage instead of relying on monitoring alone.
Ignoring the skill requirements of ZFS tuning and SAN alignment
OpenZFS and TrueNAS SAN iSCSI both require deeper storage expertise because pool tuning parameters like cache behavior and recordsize impact performance alignment. Rockstor also depends on strong dataset design understanding, and mismatched ZFS tuning increases operational overhead for production workloads.
Assuming RDMA drivers replace SAN fabric orchestration and management
NVIDIA MOFED OFED accelerates low-latency storage networking using RDMA verbs but it does not replace SAN fabric management or storage orchestration. SAN teams still need target presentation and operational management choices like Open iSCSI Target (Linux LIO) or SAN array management like NetApp SANtricity.
Choosing a product without a fit to the operating model of the consumers
VMware vSAN is tightly coupled to VMware ESXi and vCenter operations, so non-VMware consumers typically need additional integration rather than direct storage access. IBM Spectrum Scale (formerly GPFS) targets scalable shared file workloads with cluster semantics, so it is not a direct substitute for block-only SAN LUN provisioning tools like TrueNAS SAN iSCSI or Open iSCSI Target (Linux LIO).
How We Selected and Ranked These Tools
