IBM 01LJ794 1.2TB 10K RPM SAS 12Gb/s 2.5-inch enterprise hard drive, FRU 01LJ787, for SFF bays in IBM storage systems.
This is a refurbished IBM 1.2TB SAS hard drive, part number 01LJ794 and FRU 01LJ787, built by Seagate as model ST1200MM0099 (Seagate part number 1XH200-039). The IBM label also carries part number 01LJ796. It is a 2.5-inch small-form-factor mechanical drive spinning at 10,000 RPM on a dual-port 12Gb/s SAS interface, which suits enclosures with redundant controllers or multipath cabling. Storage administrators and integrators in Qatar buy it as a like-for-like replacement or an additional spindle in IBM System Storage equipment that lists these part numbers. The 10K spindle speed gives lower access latency than 7.2K nearline disks, and more capacity per pound than flash. That makes it a common member of RAID 5, 6 and 10 arrays holding virtual machine datastores, databases with moderate random I/O and general file shares. We hold it in Doha under SKU HDD-1.2TB-SAS10K-IBM.
HDD-1.2TB-SAS10K-IBMSpecification
This is a performance-tier spinning disk: 10,000 RPM sits between 7.2K nearline capacity drives and SSDs. The dual-port SAS link lets two controllers or two cable paths reach the same disk, which is what redundant-controller storage enclosures expect.
On a 6Gb/s SAS controller the link is limited to 6Gb/s, which has little practical effect on a single 10K disk. A SATA-only port cannot drive a SAS device, so the host must have a SAS controller or SAS backplane.
Installation
The drive is a bare 2.5-inch unit, so it needs the carrier that matches the target system before it goes into a bay. In a hot-swap SAS bay behind a RAID controller it can be fitted with the system running: pull the failed disk, move it out of its carrier or use a matching carrier, slide the new drive in until it seats, and let the controller start the rebuild. Match the IBM FRU against the drives already installed, and match the sector format as well, because arrays generally expect every member to share the same sector size and may refuse a mismatched disk as a replacement or spare. In a 3.5-inch bay it needs an adapter designed for that system to align the connector with the backplane.

Our team in Doha answers specification and compatibility questions during working hours.
Ask on WhatsApp sales@serverdove.comWhat is the difference between IBM 01LJ794 and 01LJ787?
01LJ794 is the IBM part number and 01LJ787 is the FRU (field replaceable unit) number for the same drive. Service documentation and parts lists often quote the FRU, while the part number appears elsewhere on the label. Both identify this 1.2TB 10K SAS 2.5-inch drive, and either can be used to match an existing installed disk.
Which Seagate drive is inside this IBM disk?
The drive is labelled Seagate model ST1200MM0099, Seagate part number 1XH200-039. IBM sources it from Seagate and supplies it under its own part numbers. The Seagate model number is useful when checking manufacturer data sheets, while the IBM numbers are what IBM systems and parts lists reference.
Will this drive work on a 6Gb/s SAS controller?
SAS is backward compatible, so a 12Gb/s SAS drive negotiates down to 6Gb/s on an older SAS controller or backplane. The link speed is then limited to 6Gb/s, which has little practical effect on a single 10K spinning disk. It will not work on a SATA-only controller, as SATA ports cannot drive SAS devices.
Can I use this drive in a non-IBM server?
Physically and electrically it is a standard 2.5-inch SAS drive, so it can connect to SAS controllers in other systems. Some server and storage vendors check drive firmware or vendor identity and may flag non-native drives as unsupported or third-party. Check how the target controller treats non-branded drives before relying on it for production arrays.
How does a 10K SAS drive compare with 7.2K nearline SAS?
A 10,000 RPM drive has shorter rotational latency and faster seeks than a 7,200 RPM nearline drive, which helps random I/O such as virtual machines and databases. Nearline drives offer much larger capacities per disk at lower cost per terabyte. 10K drives are typically chosen for performance tiers and nearline drives for bulk or backup storage.
What sector format does this drive use?
The sector format is not printed on the drive label, so it should be confirmed from the drive itself before adding it to an existing array. Storage arrays generally expect all members to share the same sector size, and a mismatch can prevent the drive from being accepted as a replacement or spare.
Does this drive fit 3.5-inch bays?
This is a 2.5-inch small-form-factor drive intended for SFF bays. Installing it in a 3.5-inch bay requires a carrier or adapter designed for that system that holds a 2.5-inch drive and aligns its connector with the backplane. Without one, the connector will not line up with a 3.5-inch backplane.
What does refurbished mean at ServerDove?
Off-lease or decommissioned enterprise hardware that we clean, test and reset in Doha. Every unit goes through POST, burn-in, memory and drive checks and a power-supply check, with firmware and BIOS returned to defaults and drives securely erased.
Can I ask about the exact unit before I buy?
Yes. Message us the SKU on WhatsApp and we will confirm the condition and configuration of the unit in stock, with photos if you want them.
How fast is delivery in Qatar?
Orders ship from Doha and arrive within one working day anywhere in Qatar. Delivery is free on orders over QAR 300.
Can I collect in person?
Yes, from Nuaija Office 7, Doha, usually within 24 hours of ordering. Choose pick-up at checkout and we will message you when it is ready.
What warranty is included?
A 6-month hardware warranty from the delivery date, covering the unit as supplied. If a part fails we repair or replace it. Full terms are on the warranty page.
What is your return policy?
If the unit arrives faulty or not as described, tell us and we will collect it and replace or refund it. Full terms are on the Refund Policy page.

Why buy refurbished
Enterprise hardware, tested in Doha, at a fraction of the price of new
Every unit we sell has already proven itself in a data centre. We test it again, grade it, and back it with a warranty before it leaves our stock.
Tested before it ships
POST, burn-in, memory and power-supply checks on every unit. Anything that fails is repaired or pulled from stock, not sold.
Same performance, lower cost
A Xeon runs the same workloads whether it is new or two years old. Spend the difference on more CPUs, memory or storage.
In stock, not on order
New enterprise hardware can take weeks or months to arrive. Ours is on the shelf in Doha and delivered across Qatar within a day.
Warranty and local support
Every unit is covered. Installation, configuration and hardware support are handled by our own team in Qatar, not a call centre abroad.
