Product Description
IBM ACKS 300 GB 15,000 rpm 6 Gb SAS 3.5 Inch HDD
IBM ACKS 300 GB 15,000 rpm 6 Gb SAS 3.5 Inch HDD on DataTechComputer.com describes it as an optional feature (#ACKS) providing one 6 Gb SAS disk drive. This is a 300 GB, 15K RPM enterprise SAS HDD packaged as a 2.5-inch drive in a 3.5-inch carrier (for compatibility with 3.5-inch LFF bays). It is optimized for high-performance, low-latency workloads requiring fast random access in supported enclosures.
This drive is specifically supported in 12-bay LFF enclosures for the IBM Storwize V3700 family (and related legacy midrange systems like V3500), offering significantly higher IOPS and lower seek times compared to 10K or 7.2K drives for performance-sensitive applications.

Configuration Options
The base offering is a single drive (#ACKS). Common associated IBM options for Storwize V3700 environments include:
- Drive Fillers/Blanks: For unused bays to maintain proper airflow and cooling
- Other Drives: Intermix with supported SAS/SSD/NL-SAS drives in the same enclosure (e.g., 7.2K NL-SAS for capacity tiers, SSDs for ultra-high IOPS)
- No additional adapters or licenses required for basic installation
These support high-performance tiered or dedicated storage configurations in compatible 12-bay LFF enclosures.
Compatibilities
The IBM ACKS 300 GB 15K SAS HDD is compatible with:
- Enclosures: IBM Storwize V3700 12-bay LFF models (control and expansion enclosures supporting 3.5-inch bays; also supported in Storwize V3500 in some references).
- Systems: Storwize V3700 family (2072 series); inherits full Spectrum Virtualize features including virtualization, thin provisioning, Easy Tier (for tiering with SSD/NL-SAS), RAID 0/1/5/6/10, FlashCopy snapshots, and remote mirroring.
- Operating Systems / Servers: Broad support via Storwize V3700 host connectivity (8 Gb FC, 1 Gb/10 Gb iSCSI/FCoE); compatible with major OS including Microsoft Windows Server, Red Hat/SUSE Linux, VMware vSphere/ESXi, IBM AIX, Oracle Solaris, HP-UX.
- Restrictions: Limited to 12-bay LFF enclosures in Storwize V3700 (and V3500); not for SFF-only bays or later generations (e.g., V7000 Gen1/Gen2, V5000, FlashSystem models use different codes like 00MJ137 equivalents or newer); ensure firmware level supports the drive for optimal reliability and performance.
This enables high-performance capacity addition in legacy Storwize V3700 configurations, ideal for I/O-intensive or tiered workloads.
The unit comes with a 60-day warranty for added assurance.
