LaCie 8big Rack Thunderbolt 2 User Manual 5 LACIE 8BIG RACK THUNDERBOLT 2: ADVANCED STORAGE TECHNOLOGY THUNDERBOLT 2 TECHNOLOGY The LaCie 8big Rack Thunderbolt 2 uses Thunderbolt 2 technology, the fastest, most versatile connection for your computer. While first generation Thunderbolt technology transfer rates are 10Gb/s bi-directional, Thunderbolt 2 technology provides 20Gb/s bi-directional. Additionally, Thunderbolt 2 technology gives priority to the video stream, apportioning the required bandwidth for playback. This is a critical advantage when working with high-end video and 3D graphics. For example, a film editor is working with two streams, 4K video at 12Gb/s and data at 4Gb/s. Whereas first generation Thunderbolt technology may experience difficulty with the video signal, Thunderbolt 2 technology allows it to pass without a problem, dividing the bandwidth as needed for playback. Important cable info: When connecting your Thunderbolt enclosure to a computer or compatible devices, use cables specifically constructed to support Thunderbolt technology. Important info: A Thunderbolt enclosure must be connected to a computer that supports Thunderbolt technology. While the ports on the back of the device can easily seat Mini DisplayPort cable ends for daisy chaining displays, the Thunderbolt storage will only work when connected to a computer that supports Thunderbolt technology.

LaCie 8big Rack Thunderbolt 2 User Manual 37 POWERING OFF THE LACIE 8BIG HARD DRIVES: IDLE MODE Make certain that the LaCie 8big is not in use and that there are no active transfers. 1. Eject the LaCie 8big volumes from your computer. 2. Apply a short push on the power button. See the explanations below to learn how to apply a short push and a 3. long push. The status LED blinks slowly while the hard drive LEDs turn off. 4. Thunderbolt 2 and first generation Thunderbolt devices daisy-chained to the enclosure receive power when the LaCie 8big is in idle mode. POWERING OFF Make certain that the LaCie 8big is not in use and that there are no active transfers. 1. Eject the LaCie 8big volumes from your computer. 2. Apply a short push on the power button. See the explanation below regarding a short push and a long push. 3. The status LED blinks slowly while the hard drive LEDs turn off. It is now safe to unplug the power cables from the device. 4. Important info: LaCie does not recommend applying a long push to power off the enclosure. See the explanation below for the long push. Short push Important info: Always eject the volume from your computer before applying a short push. A short push is a manual depression on the power button that lasts no longer than one second. When the product is operating, a short push on the power button will spin down the hard drives within the enclosure. The Thunderbolt ports remain active and are available for daisy chaining. This is called idle mode. For example, a display that is daisy chained to the LaCie 8big will remain available to the computer following a short push. Short push and RAID synchronization Applying a short push during RAID synchronization spins the hard drives down. The RAID synchronization continues the next time you spin the hard drives up via a short push.
Page: 34
LaCie 8big Rack Thunderbolt 2 User Manual 38 Long push A long push is a manual depression on the power button that lasts more than four seconds. When the product is operating, a long push will cut the power from the LaCie 8big, forcing it to shut down immediately. A long push is not recommended as it may result in data loss. Therefore, it should only be used when troubleshooting a problem. Removing the Thunderbolt cable during operation It is highly recommended that users maintain the Thunderbolt cable connection between the computer and the LaCie 8big during operation. Removing the cable during operation can have serious consequences, such as lost data. Disconnecting the Thunderbolt cable during RAID synchronization cuts communication between the computer and the storage. While the synchronization will continue, there is a strong risk of losing data.

LaCie 8big Rack Thunderbolt 2 User Manual 39 DAISY CHAIN Use the enclosure's two Thunderbolt 2 technology ports for: Direct connection to a computer that is compatible with Thunderbolt 2 technology or first generation ■ Thunderbolt technology Daisy chaining with devices and displays that are compatible with Thunderbolt 2 technology and first ■ generation Thunderbolt technology DAISY CHAIN: THUNDERBOLT 2 TECHNOLOGY AND FIRST GENERATION THUNDERBOLT TECHNOLOGY Thunderbolt 2 technology is an update of first generation Thunderbolt technology. While Thunderbolt technology continues to provide impressive transfer rates of up to 10Gb/s bi-directional, Thunderbolt 2 technology offers improved performance with a potential of up to 20Gb/s bi-directional. Thunderbolt 2 technology also gives you greater flexibility when using video and data, assigning greater throughput to the stream that carries the heavier load. You must have a computer that supports Thunderbolt 2 technology in order to take advantage of the updates in performance and the intelligent sharing of bandwidth. Similar to first generation Thunderbolt technology, a single Thunderbolt 2 technology daisy chain can have up to seven devices, including the computer. For example, you can daisy chain five LaCie 8big Rack Thunderbolt 2 enclosures on the same line with a display. Provided that your computer supports Thunderbolt 2 technology, transfer rates have the potential to reach up to 20Gb/s bi-directional for all devices. You can also add the LaCie 8big to a daisy chain that includes first generation Thunderbolt technology devices. For example, your computer supports Thunderbolt 2 technology and you add the LaCie 8big to a daisy chain that includes three first generation Thunderbolt technology storage devices and a display with a MiniDisplay port. In such a case, make certain that the LaCie 8big is the first enclosure connected to the computer. You can lose the higher performance offered by Thunderbolt 2 technology if a Thunderbolt 2 device is daisy-chained behind first generation Thunderbolt devices and/or displays.
Page: 36
LaCie 8big Rack Thunderbolt 2 User Manual 40 How to daisy chain Connect the cable to one of the interface ports on the back of the LaCie 8big and to your computer. The additional port may be used to daisy chain compatible first generation Thunderbolt and Thunderbolt 2 peripherals, such as hard drives and monitors. If you have another Thunderbolt 2 storage device, make certain to connect it to the LaCie 8big before adding first generation Thunderbolt technology devices and/or displays. Important cable info: When connecting your enclosure to a computer or compatible devices, use cables specifically constructed to support Thunderbolt technology. Thunderbolt technology cables are compatible with Thunderbolt 2 technology devices and first generation Thunderbolt technology devices. Important info: To reach Thunderbolt 2 technology transfer rates of up to 20Gb/s bi-directional, the LaCie 8big must be connected to a computer that supports Thunderbolt 2 technology. Connecting the LaCie 8big to a computer that supports first generation Thunderbolt technology allows for transfer rates up to 10Gb/s bi-directional. Daisy chain: idle mode You can daisy chain Thunderbolt 2 technology and first generation Thunderbolt technology devices even when the hard drives within the LaCie 8big are spun down. To spin down the hard drives, apply a short push on the power button (see Operation). The status LED blinks slowly, indicating that the LaCie 8big is in idle mode.

Page: 38
LaCie 8big Rack Thunderbolt 2 User Manual 42 RAID The information below provides a basic guide to the RAID modes available to the LaCie 8big Rack Thunderbolt 2. Note that the levels of performance and protection differ based upon the number of drives in a volume. For instructions on how to configure RAID, see the LaCie RAID Manager User Manual. RAID EXAMPLE The level of RAID available to a volume is contingent upon the amount of hard drives. For example, a volume with four hard drives supports all levels of RAID except for RAID 1, which is not compatible with volumes greater than two hard drives. RAID 0 appears to be the best choice for a volume with four hard drives since it offers 100% storage capacity and the best performance. However, RAID 0 does not provide data protection in case of drive failure. Further, its performance is not much greater than RAID 5, which includes data protection in case one drive should fail. RAID 6 and, in unique cases, RAID 10, can provide data protection in the event that two drives fail. RAID LEVELS Review the summaries of each RAID before selecting the configuration for the LaCie 8big storage. RAID mode Minimum hard drives JBOD 1 RAID 0 2 RAID 1 2 RAID 5 3 RAID 6 4 RAID 10 4
Page: 39
LaCie 8big Rack Thunderbolt 2 User Manual 43 JBOD (Just a Bunch of Disks) Hard drives in a JBOD configuration store data sequentially. For example, data is written to Disk 1 first. Once Disk 1 is full, data will be written to Disk 2, then Disk 3, etc. Two advantages to this level of RAID are the availability of 100% of the hard drives’ total storage capacity and easy expansion. However, all data will be lost if a single hard drive fails.
Page: 40
LaCie 8big Rack Thunderbolt 2 User Manual 44 RAID 0 RAID 0 is the fastest RAID mode since it writes data across all of the volume's hard drives. Further, the capacities of each hard drive are added together for optimal data storage. However, RAID 0 lacks a very important feature: data protection. If one hard drive fails, all data becomes inaccessible. A recommended option is RAID 5, which offers comparable performance and data protection in case a single drive fails.
Page: 41
LaCie 8big Rack Thunderbolt 2 User Manual 45 RAID 1 RAID 1 provides enhanced data security since all data is written to each hard drive in the volume. If a single hard drive fails, data remains available on the other hard drive in the volume. However, due to the time it takes to write data multiple times, performance is reduced. Additionally, RAID 1 will cut hard drive capacity by 50% or more since each bit of data is stored on all the hard drives in the volume.
Page: 42
LaCie 8big Rack Thunderbolt 2 User Manual 46 RAID 5 RAID 5 writes data across all hard drives in the volume and a parity block for each data block. If one physical hard drive fails, the data from the failed hard drive can be rebuilt onto a replacement hard drive. While the files stored on a RAID 5 volume remain intact should one hard drive fail, data can be lost if a second hard drive fails before the RAID is rebuilt with the replacement hard drive. A minimum of three hard drives is required to create a RAID 5 volume. RAID 5 offers comparable performance to RAID 0 with the advantage of protecting data. Additionally, you still have 75% of the storage capacity of a RAID 0 array (based upon total available hard drives and storage capacities).
Page: 43
LaCie 8big Rack Thunderbolt 2 User Manual 47 RAID 6 RAID 6 writes data across all hard drives in the volume and two parity blocks for each data block. If one physical hard drive fails, the data from the failed hard drive can be rebuilt onto a replacement hard drive. With two parity blocks per data block, RAID 6 supports up to two hard drive failures with no data loss. RAID 6 synchronizing from a failed hard drive is slower than RAID 5 due to the use of double parity. However, it is far less critical due to its double-disk security. A minimum of four hard drives is required to create a RAID 6 volume. RAID 6 offers very good data protection with a slight loss in performance compared to RAID 5.
Page: 44
LaCie 8big Rack Thunderbolt 2 User Manual 48 RAID 10 RAID 10 combines the protection of RAID 1 with the performance of RAID 0. Using four hard drive as an example, RAID 10 creates two RAID 1 segments, and then combines them into a RAID 0 stripe. With eight hard drive, the RAID 0 stripe will include four RAID 1 segments. Such configurations offer exceptional data protection, allowing for two hard drive to fail across two RAID 1 segments. Additionally, RAID 10 writes data at the file level and, due to the RAID 0 stripe, gives users higher performance when managing greater amounts of smaller files. This means a more generous input output per second for data, referred to as IOPS. RAID 10 is a great choice for database managers that need to read and write a multitude of smaller files across the volume's hard drives. The impressive IOPS and data protection offered by RAID 10 gives database managers impressive reliability both in keeping files safe and rapid access.
Page: 45
LaCie 8big Rack Thunderbolt 2 User Manual 49 RAID+Spare A RAID+Spare volume gives you a “hot-spare” that is ready to synchronize data immediately should a hard drive fail. If a hard drive in the volume fails, the data starts to synchronize with the spare. The clear advantage for a RAID volume with a spare is that you do not have to wait for a replacement hard drive. However, the spare cannot be used as storage during standard operation since its sole task is to take over should a hard drive fail. You can replace the failed hard drive once synchronization is complete and use it as the new hot spare. Important info: For RAID+Spare volumes, data remains intact when a single hard drive fails and the spare begins synchronizing automatically. However, if a second hard drive in a RAID 5 volume fails before synchronization is complete, all data in the volume will be lost. The same is true for a RAID 1 volume. In the case of RAID 10, the second failed hard drive would have to be on the same mirrored set as the spare hard drive that is synchronizing data for the RAID to break. RAID 6 allows for two hard drives to fail.

LaCie 8big Rack Thunderbolt 2 User Manual 50 HARDWARE MAINTENANCE The LaCie 8big Rack Thunderbolt 2 has a front chassis and rear chassis, each with its own cover. Review the details below for hardware module locations and, where applicable, replacement. Important info: Refer to the product's Warranty Information before performing any hardware repairs or maintenance that is not described in this manual. PRECAUTIONS “Hot-swapping” means that you can perform maintenance or upgrade hardware while the LaCie 8big Rack ■ Thunderbolt 2 is powered on. The LaCie 8big features three hot-swappable parts: hard drives; fans; and power supply units. During operation, all provided hardware (including the installed hard drives in their frames) should remain in ■ place for optimal air flow. Users with less than eight hard drives are not required to install empty hard drive trays in the enclosure. Airflow and fan performance are regulated by temperature. Observe all conventional ESD precautions when handling the LaCie 8big parts. ■ Apart from hot-swapping operations, the front top cover should be removed only when the unit has been ■ turned off and allowed to cool down. Potential hazards of opening the cover while the product is powered on includes, but is not limited to, hot surfaces and exposed parts. The rear of the LaCie 8big features parts integral to operation. However, none of the parts are hot-swappable ■ or serviceable by users. Removing the rear cover without the express permission of LaCie technical support will void the warranty for the LaCie 8big Rack Thunderbolt 2. Important info: Your LaCie professional DAS gives you instant updates on the health of the enclosure and its hard drives. In addition to LED status indications, you can configure the system to send you email alerts (see the user manual for LaCie RAID Manager). Further, the enclosure will sound an alarm should a serious error occur (see System Overview). It is highly recommended that you address all warnings and alerts immediately. Ignoring a potential problem or urgent hardware alert can lead to irreparable damage to the DAS and a serious loss of data.
