ARCHITECTURAL ADVANTAGES

Why Enterprises Transition from Three-Tier to HCI

Traditional multi-vendor arrays demand complex Fibre Channel SAN zoning, proprietary storage controller upgrades, and disjointed maintenance renewals.

Silo Elimination & Consolidation

Collapses separate physical SAN/NAS switches, external array controllers, and compute servers into unified high-density x86 building blocks managed through a single software pane.

Predictable Linear Scalability

Scale compute, memory, and high-performance storage in lockstep. Adding an additional node immediately expands both IOPS and aggregate raw capacity without forklift upgrades.

N+1 & N+2 Failure Domains

Distributed software-defined storage maintains data parity across discrete physical chassis. Complete host loss or drive failures trigger automated background re-mirroring with zero data loss.

Ultra-Low NVMe-oF & RoCE Latency

Eliminates legacy Fibre Channel HBA overhead by leveraging direct-attached NVMe storage caddies interlinked via dual 25GbE RDMA (RoCE v2) east-west fabric networks.

INFRASTRUCTURE ARCHITECTURE TRADE-OFFS

HCI vs. Traditional Three-Tier vs. Dedicated AI/HPC

HCI is not a universal panacea for every enterprise use case. Our architecture desk guides you toward the optimal model based on workload symmetry and scale.

High Fit for 80% of Enterprise Virtualization

Hyperconverged Infrastructure (HCI)

OPTIMAL FOR:

General virtualization, mixed corporate workloads, VDI, branch offices, rapid linear scaling.

LIMITATIONS & CONSTRAINTS:

Storage and compute scale together; extreme unbalanced capacity growth (e.g., 500TB storage for only 4 CPUs) can become commercially inefficient.

High Fit for Asymmetric Petabyte Storage

Traditional 3-Tier (Compute + SAN/NAS)

OPTIMAL FOR:

Massive scale-up relational databases (Oracle RAC, SAP HANA), massive unstructured data lakes (multi-PB archives).

LIMITATIONS & CONSTRAINTS:

Operational complexity: requires managing dedicated Fibre Channel fabrics, zoning, external LUN masking, and disparate support contracts.

Dedicated Specialized Compute Fabric

Dedicated AI/HPC GPU Clusters

OPTIMAL FOR:

Distributed LLM training, high-throughput model inferencing, molecular modeling, parallel CFD simulations.

LIMITATIONS & CONSTRAINTS:

Hypervisor virtualization introduces memory and PCIe communication overhead. Demands bare-metal scheduling and non-blocking InfiniBand fabrics.

Vendor-Neutral Recommendation:If your storage capacity demands grow at 3x or 5x the rate of your CPU requirements (such as multi-petabyte PACS imaging or video telemetry archives), a hybrid approach using independent SAN/NAS expansion enclosures alongside an HCI compute cluster frequently yields superior long-term economics.

SIZING & DISCOVERY PARAMETERS

Information Needed for an Accurate HCI Sizing BOM

To provide an exact, competitively priced Bill of Materials (BOM) with manufacturer warranty verification, our engineering desk reviews these 6 parameters.

Step 01

Workload Inventory & IOPS Baseline

We audit your existing VM footprint: total vCPUs, committed RAM, aggregate working-set storage, peak write IOPS, and read/write ratio (e.g. 70/30).

Step 02

Consolidation Ratio & Core Allocation

Calculating safe vCPU-to-pCPU ratios (typically 3:1 to 4.5:1 for enterprise virtualization) ensuring no virtual machine experiences CPU ready time spikes.

Step 03

Memory Sizing & N+1 Headroom

Allocating host DDR5 ECC RAM such that if any single host fails, the remaining N-1 nodes absorb 100% of the virtual machines with at least 20% free RAM headroom.

Step 04

Raw to Usable Storage & Erasure Coding

Factoring in RAID-1 mirroring (2x raw requirement) or RAID-5/6 erasure coding (1.33x raw requirement), plus 20% slack space for disk balancing and snapshot operations.

Step 05

Network Backplane & RDMA Fabric

Ensuring dual top-of-rack 25GbE switches provide dedicated non-blocking storage VLANs with RoCE v2 and Priority Flow Control (PFC) to eliminate east-west packet drops.

Step 06

Software Ecosystem & Licensing Match

Selecting the commercially and technically appropriate hypervisor stack: VMware vSAN ReadyNode licensing, Nutanix Cloud Platform (AOS/AHV), or enterprise Proxmox VE.

FREQUENTLY ASKED QUESTIONS

Hyperconverged Infrastructure (HCI) FAQ

Guidance for infrastructure architects, CIOs, and data center procurement teams.

What is the minimum number of nodes required to deploy an enterprise HCI cluster?

Standard enterprise HCI clusters require a minimum of 3 nodes to maintain distributed quorum and tolerate a complete single-node failure without degrading data availability. For mission-critical environments, a 4-node cluster is strongly recommended so routine firmware updates or maintenance can be executed without leaving the cluster temporarily vulnerable to an unexpected second hardware fault. Specialized 2-node ROBO topologies are also supported using an external witness.

How does Patel Galaxify Solutions distinguish between vSAN ReadyNodes and proprietary appliances?

vSAN ReadyNodes are pre-validated, factory-configured server configurations from Tier-1 OEMs (Dell, HPE, Lenovo) that are certified by the hypervisor vendor. They utilize standard enterprise server hardware components, preventing vendor lock-in and allowing flexible lifecycle hardware upgrades, unlike proprietary proprietary locked-box appliances.

Can we mix different server generations or drive sizes within the same HCI cluster?

While modern software-defined storage layers allow heterogeneous node additions, best practice dictates deploying identical node configurations within the same storage pool to prevent IOPS bottlenecks and imbalanced capacity distribution. When adding new generations, we configure dedicated new resource pools or execute rolling node upgrades.

How do you handle workload migration from legacy SAN/servers to the new HCI cluster?

We plan and assist with live and scheduled Virtual-to-Virtual (V2V) and Physical-to-Virtual (P2V) migrations. By cross-connecting temporary 10G/25G uplinks between the legacy SAN and the new HCI cluster, virtual machines can be migrated live via storage vMotion with zero production application downtime.

What Annual Maintenance Contracts (AMC) and on-site hardware support are available?

We provide both OEM-backed support contracts (Dell ProSupport Plus, HPE Tech Care) and Patel Galaxify Solutions comprehensive AMC options. Support levels range from 8×5 Next Business Day part dispatch to 24×7 Mission-Critical 4-hour on-site engineering response, backed by staged buffer node parts across Bengaluru and Jaipur.
