Product Description
IBM ACKL 1.8 TB 10,000 rpm 12 Gb SAS 3.5 Inch HDD
IBM ACKL 1.8 TB 10,000 rpm 12 Gb SAS 3.5 Inch HDD feature (#ACKL) providing one 12 Gb SAS disk drive formatted with 4,096 (4K) byte sectors (4Kn). This is a high-performance enterprise SAS HDD (10K RPM) packaged as a 2.5-inch drive in a 3.5-inch carrier for compatibility with LFF bays. When installed in a Storwize V3700, it operates at a maximum data transfer rate of 6 Gb/s due to system limitations, despite the 12 Gb/s interface capability.
It is designed for 12-bay LFF enclosures in the IBM Storwize V3700 family, offering faster access times than NL-SAS drives for mixed or performance-sensitive workloads.

Configuration Options
The base offering is a single drive (#ACKL). 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 high IOPS)
- No additional adapters or licenses required for basic installation
These support performance-tiered storage configurations in compatible 12-bay LFF enclosures.
Compatibilities
The IBM ACKL 1.8 TB 10K SAS HDD is compatible with:
- Enclosures: IBM Storwize V3700 12-bay LFF models (control and expansion enclosures supporting 3.5-inch bays).
- 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; not for SFF-only bays or later generations (e.g., V7000 Gen1/Gen2, V5000, FlashSystem models use different codes like 00MJ135 equivalents or newer); effective speed capped at 6 Gb/s in V3700; ensure firmware level supports the drive for optimal reliability and performance.
This enables high-performance capacity addition in legacy Storwize V3700 configurations, ideal for tiered or mixed workloads.
The unit comes with a 60-day warranty for added assurance.
