K2P89B HPE 3PAR StoreServ 1.92TB SAS 12Gbps SFF MLC SSDs

The K2P89B model refers to a class of enterprise-grade, high-performance solid state drives (SSDs) designed specifically for the HPE 3PAR StoreServ 8000 series storage platforms. These SSDs use SAS (Serial Attached SCSI) 12 Gbps interfaces in a 2.5-inch small form factor (SFF) design and leverage MLC (multi-level cell) NAND technology to deliver a balance of capacity, endurance, and performance. In the context of storage architectures for data centers, virtualization deployments, cloud infrastructure, and high-transaction workloads, these drives fill a critical niche as high-throughput, low-latency data storage components.

As part of a broader category, “HPE 3PAR StoreServ Enterprise SSDs,” the K2P89B drives fall under a subcategory of “SAS 12 Gbps MLC SSDs” and further into “2.5-inch SFF format.” This category includes devices tailored for HPE’s 3PAR line, encompassing varying capacities (e.g. 400 GB, 800 GB, 1.6 TB, 1.92 TB, 3.84 TB), different endurance classes (such as high endurance, mixed workload, or read-optimized), and sometimes different firmware or overprovisioning variants. The K2P89B 1.92 TB model is frequently used in mission-critical environments requiring consistent low latencies under heavy I/O workloads.

Key Attributes

Interface and Form Factor

The K2P89B series utilizes a SAS 12 Gbps interface, enabling full-duplex communication and high sustained throughput. This high interface bandwidth is essential to maintain low latency under mixed read/write workloads typical in virtualized and database storage tiers. The 2.5-inch SFF format ensures compatibility with dense server and array slots, enabling efficient rack usage. The small form factor aids in thermal design and simplifies mechanical integration within 3PAR enclosures or interposers.

NAND Type and Endurance

Multi-Level Cell (MLC) NAND provides a compromise between cost and endurance, offering better write cycle durability than TLC while maintaining higher bit density than SLC. In enterprise SSDs like K2P89B, the NAND is further optimized with wear leveling, overprovisioning, and robust error correction (ECC) to sustain high I/O loads over multi-year service lifecycles. The drive may support a specific DWPD (Drive Writes Per Day) rating appropriate for enterprise workloads.

Reliability, Endurance, and Data Integrity

Enterprise SSDs of this class include advanced features such as end-to-end data path protection, power-loss protection capacitors or firmware safeguards, and strong ECC algorithms to correct bit errors. In addition, SMART monitoring, media wear indicators, and built-in self-test routines allow integration with storage management systems for proactive maintenance. Drive longevity is governed by total terabytes written (TBW) metrics and periodic health check mechanisms.

Use Cases and Deployment Scenarios

Primary Storage for Virtual Machines

In virtualized environments (e.g. VMware vSphere, Microsoft Hyper-V, or container platforms), the K2P89B 1.92 TB SAS SSD is well suited as primary data tier media for hosting virtual machine disks (vDisks). With low latency and high IOPS, it can support many VMs concurrently, reducing performance contention. Because of its enterprise design, it helps maintain consistent performance even under bursty read/write patterns typical of virtualization workloads.

Database and OLTP Systems

Transactional database systems such as Oracle, Microsoft SQL Server, or PostgreSQL benefit from the low-latency random I/O performance of these SSDs. The 1.92 TB capacity allows for substantial in-database working set storage, caching layers, indexes, or log volumes. The high endurance design ensures reliability under sustained write loads.

Hybrid Storage Architectures

Within HPE 3PAR StoreServ arrays, these SSDs can be deployed alongside SAS HDDs or NL-SAS disks in tiered storage layouts. The SSDs act as “flash tier” hot storage, accelerating read/write operations, while spinning disks manage capacity for colder data. Data movement policies automatically migrate frequently accessed data onto SSD tiers. The K2P89B model is often configured in RAID groups or distributed across nodes within the 3PAR mesh.

Virtual Desktop Infrastructure (VDI)

In VDI deployments handling hundreds or thousands of desktop sessions, storage latency and throughput are key bottlenecks. The K2P89B SSD delivers low-latency IOPS to serve boot storms, user logins, or persistent desktops at scale. The 1.92 TB size allows multiple full-image sets alongside user data, while performance holds under periods of intense concurrent access.

Analytics, Caching, and Tier-0 Storage Extension

Advanced analytics workloads, in-memory hybrid databases, or caching layers (e.g. Redis, memcached) can use the K2P89B SSD as backing storage to support instantly responsive queries. The drive’s performance envelope and enterprise features make it reliable for even bursty, high-volume workloads in cloud or big-data stacks.

Data Protection and Redundancy

To mitigate hardware failure risk, use redundant RAID levels (RAID-5, RAID-6, or dual-parity schemes). Because enterprise SSDs like K2P89B often have much lower failure rates than spinning media, the emphasis is on protecting against latent errors or controller anomalies. It’s also important to schedule periodic consistency checks or scrubbing routines to detect silent errors.

Hot-Swap and Redundancy Support

The 2.5-inch SAS SSD format supports hot-swapping in most enterprise chassis that support it. When a failure or removal occurs, the array can rebuild from parity or redundancy, provided that spare drives are available. The drive’s SMART and event logging should integrate with the management stack to raise early alerts for drive health shifts.
