HPE MSA 2070 SFF 2X10/25GBE Iscsi 4-PORT Controller Storage Array - P89070-B25

HPE P89070-B25 Modular SAN Storage Array

Overview

The HPE P89070-B25 is a 24-bay SFF (Small Form Factor) modular storage array designed for data center and surveillance deployments where you need rack-density without sacrificing redundancy or performance. This unit pairs dual 10/25GbE iSCSI 4-port controllers with hot-swappable drive bays and redundant power — the core infrastructure choice when you're building a scale-out NAS or backup tier for video retention, archival, or general enterprise storage.

The P89070-B25 (often searched as P89070 B25) supports up to 7.37 petabytes of raw capacity across its 24 SFF bays, making it economical for long-term video retention in multi-site deployments where you cannot accept single points of failure. The dual-controller iSCSI design means your surveillance NVR or backup appliance stays online even during controller maintenance or firmware updates.

Key Features

• Dual 10/25GbE iSCSI Controllers (4-port each): Eight gigabit Ethernet ports total give you fine-grained control over traffic isolation — dedicate separate ports to video ingestion, NVR replication, and administrative access without contention. 10GbE is standard; 25GbE upgrade available for shops pushing bandwidth-hungry 4K multicamera ingest or real-time sync between sites.
• 24 SFF Drive Bays: Small Form Factor chassis footprint saves rack U compared to 3.5-inch designs, but still delivers the capacity density you need for 30-day or 90-day rolling buffers on 100+ camera deployments. Each bay is hot-swappable — pull a failed drive, slot in a replacement, array continues without intervention.
• 7.37 PB Maximum Raw Capacity: Using enterprise-class SSDs or high-capacity 2.4TB SAS drives, you hit petabyte-scale storage in a single 4U footprint. Realistic effective capacity (after RAID overhead and formatting) lands around 5–6PB for typical surveillance workloads using RAID 6 or RAID 5 configurations.
• Redundant 580W Power Supplies (2x): If one PSU fails, the array continues on the surviving unit — no brownout, no data loss. Critical for unattended remote locations (branch offices, industrial sites, parking structures) where a power supply fault cannot trigger an emergency shutdown.
• Multi-Protocol Host Connectivity: Supports 16/32 Gb Fibre Channel for legacy SAN environments, 10/25GbE iSCSI for IP-based video and backup appliances, and 12Gb SAS for direct-attach configurations. Choose your transport layer based on existing infrastructure — no rip-and-replace required.
• Enterprise Modularity: Supports MSA 2070 SFF drive shelves for expansion, letting you scale capacity incrementally without replacing the core controller. Useful in surveillance environments where coverage grows quarterly but budgets come in tranches.

Integration & Compatibility

The P89070-B25 integrates natively with any iSCSI-capable NVR (Milestone Xprotect, Genetec Omnicast, Hanwha Wisenet, Axis Camera Station) or enterprise backup platform (Veeam, Commvault, NetBackup). iSCSI block-level storage is transparent to the surveillance application — your NVR sees the P89070-B25 as standard volumes, no special drivers or firmware required.

For shops already running Fibre Channel SANs or direct-attached SAS libraries, the P89070-B25 supports those protocols in parallel. Dual controllers mean you can load-balance traffic or isolate video-only workloads from administrative or backup traffic on separate controller ports, reducing latency jitter and QoS headaches.

What's in the Box

Package contents are available from your local HPE reseller or pre-sales team — dimensions and exact accessory counts vary by regional configuration. The unit ships as a complete 24-bay enclosure with both PSUs installed and controllers pre-seated; you add drives and connect network/SAS cables on-site.

Frequently Asked Questions

Q: Does the P89070-B25 support RAID 6 or RAID 10?

A: Yes. HPE Modular Storage arrays support RAID 0, 1, 5, 6, and 10 configurations. RAID 6 is standard for surveillance video retention — two simultaneous drive failures won't trigger data loss, and stripe performance on sequential read (playback) is predictable. RAID 5 reduces overhead but increases rebuild risk in large-capacity configurations.

Q: What's the maximum throughput over iSCSI on the P89070-B25?

A: Each 10/25GbE port is rated for line rate. With 4 iSCSI ports per controller (8 total), you can saturate all interfaces for a theoretical maximum of 80–200 Gbps aggregate depending on whether you're running 10GbE or 25GbE transceivers. Real-world throughput on video ingest is typically 30–60% of line rate due to overhead, network contention, and drive latency.

Q: Is the P89070-B25 NDAA Section 889 compliant?

A: Compliance status varies by specific firmware version, controller model, and drive configuration. Check with HPE sales or your channel partner for NDAA Section 889 attestation on this SKU. Do not assume compliance without signed documentation.

Q: Can I expand the P89070-B25 with additional drive enclosures?

A: Yes. MSA 2070 SFF expansion shelves attach via SAS connections and expand the LUN pool available to the P89070-B25 controllers. Scaling is non-disruptive — you can add shelves while the array is in production without interrupting existing video feeds.

Q: What is the warranty on the P89070-B25?

A: Standard warranty terms and support options are available from HPE. Contact your reseller or HPE account team for specific coverage, response-time SLAs, and spare-parts inclusion.

Q: What redundancy exists if a controller fails?

A: The dual-controller design means each controller owns half the iSCSI port pool. If one controller fails, the remaining controller remains online with reduced bandwidth, but all LUNs stay accessible. No data is lost; NVRs reconnect automatically within seconds. Both controllers share no single point of failure for data integrity.

The P89070-B25 is the right storage controller for shops migrating from direct-attached SAS libraries to iSCSI-backed NVRs without wanting to burn $200K+ on a unified storage appliance. The dual 10/25GbE controller pair is the key here — you get eight independent Ethernet ports, which means you can isolate video ingest from replication, administrative, and backup traffic without any hardware changes or network overlays.

Technical Highlights:

• Dual 10/25GbE iSCSI (4-port each): Eight Gigabit Ethernet ports deliver true traffic separation — ingest from 100+ cameras on ports 1–2, NVR replication on ports 3–4, administrative and firmware updates on a separate controller entirely. Prevents the bottleneck where your camera feed starves because backup is running.
• 7.37 PB Raw Capacity (24 SFF bays): Using 2.4TB 15K SAS drives (the surveillance standard), you fit 57.6TB raw per array. Stack three of them and you're north of 170TB effective usable storage — roughly 180 days of 1080p video from 200 cameras at standard bitrates with RAID 6. That's real retention without juggling multiple appliances.
• Redundant 580W PSUs: Two power supplies with automatic switchover means the array survives a PSU failure, a PDU circuit loss, or even a temporary brownout — all without triggering an emergency shutdown. Critical in remote or warehouse deployments where a power event can't ripple through your entire camera network.

Deployment Considerations:

• The P89070-B25 needs enterprise-class iSCSI-capable NVR software or a middleware appliance to bridge it to consumer-grade recorders. If you're running Milestone Xprotect, Genetec, or Axis Camera Station, this is plug-and-play. If you're trying to attach it to an unsupported DVR, you'll need a gateway appliance.
• Controller failover is automatic but not instantaneous — NVRs typically see a 3–5 second hiccup during a controller fault. Plan for this in high-availability setups. Dual-controller design prevents data loss, not zero-second recovery.

The P89070-B25 is the architect's choice for multi-site surveillance where you need petabyte-scale retention, controller redundancy, and the ability to isolate traffic types without paying for a full enterprise storage appliance. If you're building a regional backup tier or a high-density edge site with 200+ cameras, this is where to start.
