HPE MSA 2070 SFF SAS 12X3.84T Array - P84180-B25

HPE P84180-B25 MSA 2070 SFF SAS All-Flash Storage Array

The HPE P84180-B25 is a 2U rack-mount all-flash storage array built around twelve 3.84TB SAS SSDs — 46.08TB raw — with dual 12Gb SAS controllers designed for mid-range workloads that demand predictable low-latency performance without the complexity of enterprise-class SAN platforms. This is the kind of array that belongs in a VMware vSphere cluster, a Windows Server iSCSI target, or a Red Hat Linux production environment where you need reliable block storage without a dedicated storage administrator to keep it running. The P84180-B25 (often searched as P84180 B25) sits squarely in the MSA 2070 SFF family — a line built for straightforward deployment, not maximum flexibility.

Overview

The HPE storage line MSA 2070 is engineered for organizations that have outgrown direct-attached storage but don't need — or can't staff — the operational overhead of a full Nimble or Primera deployment. The SFF (Small Form Factor) chassis packs twelve 2.5-inch drive bays into 2U, keeping the footprint compact in space-constrained data closets and colocation racks. With redundant controllers and redundant power supplies baked in from the factory, this is not a cut-corners entry-level box — it's a properly architected HA shared storage platform at a mid-market price point.

Key Features

• 12 x 3.84TB SAS SSDs (46.08TB Raw): All-flash from the base configuration means every workload — VMs, databases, surveillance NVR targets — gets consistent sub-millisecond latency. You're not tuning a hybrid tier or waiting on spinning disks to spin up; every read and write hits flash. At 3.84TB per drive, the density is high enough that most mid-range deployments won't need immediate expansion.
• Dual 12Gb SAS 4-Port Controllers: Two controllers, each with four 12Gb SAS ports, deliver both redundancy and bandwidth. If one controller fails, the array keeps running on the other — critical for any 24/7 workload. The 12Gb SAS fabric provides roughly 2x the theoretical throughput ceiling of legacy 6Gb SAS, which matters when multiple hosts are hitting the array simultaneously.
• Up to 1.8PB Capacity with Expansion: The base 46TB raw is a starting point, not a ceiling. Storage expansion shelves can push the array to 1.8PB — so if your retention requirements grow (longer video archives, larger VM datastores, additional database instances), you add shelves rather than buying a new array. Plan your rack space accordingly from day one.
• 2 x 580W Redundant Power Supplies: Dual 580W PSUs mean a single power supply failure doesn't bring down the array. For any production workload this is non-negotiable. Each PSU is hot-swappable, so replacement happens during business hours without a maintenance window.
• Broad OS and Hypervisor Certification: Factory-certified compatibility with Windows Server, VMware vSphere, Red Hat Enterprise Linux, and SUSE SLES covers the vast majority of production environments. You're not rolling the dice on driver support or hunting for HCL entries — these are validated, supported configurations.
• 2U Rack Form Factor: Two rack units is a reasonable trade for what you get. In a standard 42U rack you can stack multiple arrays or pair this with compute nodes without burning half the cabinet on storage.

Integration & Compatibility

The MSA 2070 SFF integrates as a SAS-attached or FC-attached shared storage target for certified hypervisor environments. VMware vSphere users can present LUNs via the vSphere web client using standard iSCSI or Fibre Channel HBAs; Windows Server deployments can leverage Server Manager for iSCSI target discovery. Red Hat and SUSE environments use standard multipath I/O (MPIO) drivers. For surveillance and video workloads, the array's sequential write performance on SAS SSDs handles high-bitrate multi-stream recording without the buffer underrun issues common to spinning-disk arrays under simultaneous write load. Verify your host HBA firmware versions against the HPE SPP (Service Pack for ProLiant) compatibility matrix before deployment — mismatched HBA firmware is the most common cause of unexpected behavior on first install.

Frequently Asked Questions

Q: What drive type does the P84180-B25 ship with?

A: The P84180-B25 ships with 12 x 3.84TB SAS SSDs installed, providing 46.08TB raw all-flash capacity in the base configuration.

Q: Does the MSA 2070 SFF support capacity expansion beyond the base 12 drives?

A: Yes. The MSA 2070 platform supports expansion to up to 1.8PB through compatible expansion enclosures, allowing incremental capacity growth without replacing the base array.

Q: How many controllers does the P84180-B25 include, and are they redundant?

A: The P84180-B25 includes two 12Gb SAS 4-port controllers. Both are active, providing controller-level redundancy — if one controller fails, the other maintains array operation without interruption.

Q: What operating systems and hypervisors are certified for the P84180-B25?

A: Certified compatible environments include Windows Server, VMware vSphere, Red Hat Enterprise Linux, and SUSE SLES. Always verify specific version support against the HPE Storage Compatibility Matrix for your environment.

Q: What is the power supply configuration on the P84180-B25?

A: The array ships with two 580W redundant, hot-swappable power supplies. A single PSU failure does not impact array availability.

Q: Is the P84180-B25 suitable for video surveillance storage?

A: The all-flash SAS SSD configuration handles high-bitrate sequential write workloads well, making it suitable for multi-camera NVR targets where consistent write throughput matters. For very large-scale surveillance archives, evaluate whether the 1.8PB expansion ceiling and SSD cost-per-TB fit your retention budget versus a hybrid or SATA-based alternative.

The P84180-B25 is one of those arrays I recommend when a customer needs genuine shared-storage HA without the licensing and complexity costs that come with HPE's higher-tier platforms. The dual 12Gb SAS 4-port controllers are the spec I'd point to first — that's not just redundancy on paper, that's active-active throughput headroom that keeps the array responsive when multiple hosts are writing simultaneously, which is exactly the scenario you hit in a dense VMware cluster during backup windows.

Technical Highlights:

• 12 x 3.84TB SAS SSDs: 46.08TB raw all-flash means consistent sub-millisecond response times across all connected hosts — no spinning-disk latency spikes during random I/O workloads like VM boot storms or database checkpoint flushes.
• Dual 12Gb SAS Controllers (4-port each): Eight total 12Gb SAS host ports between both controllers gives you meaningful bandwidth headroom and true controller failover — the array does not go read-only during a controller swap.
• 2 x 580W Redundant PSUs: Hot-swap capable, so a PSU replacement is a scheduled 10-minute task, not an emergency maintenance window. For 24/7 environments this is table stakes, and it's built in here rather than an optional add-on.

Deployment Considerations:

• Plan SAS zoning before racking — with four ports per controller and dual controllers, you have flexibility in how you zone hosts, but a poorly planned fabric can negate the redundancy the dual-controller design provides. Zone each host to both controllers from day one.
• Watch the cost-per-TB math if your primary workload is bulk sequential storage (long-term video archives, cold backup targets) — 12 x 3.84TB SAS SSDs at all-flash pricing is the right call for latency-sensitive workloads, but if you're storing 90-day surveillance footage that gets read back once a week, a hybrid or SATA SSD configuration may deliver equivalent functional performance at lower cost per usable terabyte.

For a VMware vSphere environment running 20–80 VMs with mixed OLTP and general-purpose workloads in a 2U shared-storage footprint, the P84180-B25 is a well-balanced deployment — enough raw capacity to last several years, dual-controller HA without additional licensing, and a clear expansion path to 1.8PB when you need it.
