Frequently Asked Questions - Unity XT 680F DELL

How do I perform initial setup of the Unity XT 680F?

Connect the power and network cables, then access the Unisphere management interface via the dedicated management port (default IP: 192.168.1.100). Use the Initial Configuration Wizard to set up storage pools, network interfaces, and create file shares or block LUNs.

What types of drives are supported?

The Unity XT 680F supports Dell-certified 2.5-inch SAS SSDs only. For best performance, use Dell's own drives. Mixing different drive models is not recommended.

How can I expand the storage capacity?

Add a Dell Unity XT 680F expansion shelf (DAE) via SAS cables. Each DAE can hold up to 25 drives. Alternatively, replace existing drives with higher-capacity SSDs. The system supports online capacity expansion.

Does the Unity XT 680F support data deduplication and compression?

Yes, inline data reduction (deduplication and compression) is always enabled at the pool level. It works transparently and can significantly reduce storage usage, typically achieving 2:1 to 5:1 reduction.

What are the supported network protocols for file sharing?

The Unity XT 680F supports NFS (v3/v4), SMB/CIFS (v2/v3), and S3 object storage. These protocols can be used simultaneously on the same pool.

How do I replace a failed drive?

Locate the failed drive via the Unisphere dashboard (LED indicator also shows amber). Press the release button, remove the drive carrier, insert a new Dell-certified SSD, and push it back in. The system automatically rebuilds. No tools required.

Can the Unity XT 680F be configured with a redundant path?

Yes, both controllers are active-active and support multipathing. For best redundancy, connect each controller to separate Fibre Channel switches or iSCSI networks. Use MPIO on host side.

How do I update the firmware?

Download the latest Unity OE (Operating Environment) from Dell Support. Upload it via Unisphere under 'Maintenance' -> 'Software Update'. Follow the wizard; the system will non-disruptively reboot each controller.

What is the recommended cleaning procedure?

Power off the system and disconnect all cables. Use a soft lint-free cloth slightly dampened with water to clean the front bezel and chassis. Do not use any solvents or sprays. Ensure all ports are dry before reconnecting.

How do I obtain spare parts or a replacement unit?

Contact Dell EMC Support or your authorized reseller. Spare parts are field-replaceable: power supplies, fans, controllers, drives, and small form-factor pluggable (SFP) modules. Most components can be replaced while the system is running.

3. Gently push the bezel into place on the cabinet until it latches.
4. If the bezel has a lock, insert the key that shipped with your enclosure into the lock, and turn the key to lock the bezel.

Figure 9 Installing the front bezel

Connect a Windows-based computer to your storage system

Note

At the end of the power-up process, the SP Fault LED blinks in intervals of amber for one second and then blue for three seconds, indicating that the system is ready to run the Connection Utility.

You must connect a Windows-based computer to your system directly or remotely over a subnetwork. This computer will be used to continue setting up your system and must be on the same subnet as the storage system to complete the initialization.

NOTICE

Check to see if there is security software running on your workstation/laptop such as Cisco Security Agent or McAfee Host Intrusion Prevention Service that may prevent the initialized system from being detected. If there is, disable it (Windows Services) before running the initialization.

The system management ports support both IPv4 and IPv6. You can assign an IP address to a system in the following ways:

• If you are running the storage system on a dynamic network that includes a DHCP server and a DNS server, the management IP address can be assigned automatically.
• If you are not running the storage system in a network that supports DHCP or you would rather manually assign a static IP address, you must install and run the Connection Utility on the Windows-based computer.

Dynamic IP addresses (DHCP) should not be used for any components of the EMC Secure Remote Services Virtual Edition (ESRS VE) servers, Policy Manager servers, or managed devices.

NOTICE

If you use DHCP to assign IP addresses to any EMC Secure Remote Services (ESRS) components (ESRS Virtual Edition servers, Policy Manager, or managed devices), they must have static IP addresses. Leases for the IP addresses that Dell EMC devices use cannot be set to expire. It is recommended that you assign static IP addresses to those devices you plan to have managed by ESRS.

Automatically assigning a dynamic storage system management port IP address

Assigning an IP address to a storage system management port dynamically requires the following:

• Network DNS server (with dynamic DNS services enabled)
- Network DHCPv4 server and/or a DHCPv6 server and/or a router advertising DNS servers
- Connectivity between the storage system, the DHCP server, and the DNS server

The DHCP server must be configured to automatically register DHCP clients with Dynamic DNS services. By default, storage systems are configured to use DHCP for IP assignment and will accept an IP address offered by a network DHCP server.

Perform the following steps to automatically assign an IP address to your storage system management port:

Procedure

1. After you power up the storage system, check the SP Fault LED.

2. If the SP Fault LED is solid blue, a management IP address has been assigned.

3. If the SP Fault LED is solid blue for three seconds and then flashes amber for one second intervals, no management IP address has been assigned. Check the connectivity between the system, the DNS server, and the DHCP server.

4. Open a web browser and access the Unisphere management interface specifying the following as a URL in the browser's address bar: serial_number.dns_zone

where

URL string	Description
serial_number Serial number of your storage system. You can find this in the packing materials that came with your system (for example, FNM00131800283). It is also on the PSNT tag on the front of the DPE.
dns_zone Network DNS zone on which the storage system is located (for example, mylab.emc.com).

Based on the examples provided in this table, the URL to the storage system would be FNM00131800283.mylab.emc.com.

Note

If a certificate error appears, follow the instructions in your browser either to bypass the error or to install the self-signed storage system certificate. For more detail about your storage system certificate, refer to the EMC Unity Security Configuration Guide.

Manually assigning a static storage system management port IP address

To manually assign a static IP address for the storage system management port, you must install and run the Connection Utility on a Windows-based computer. The Connection Utility assigns a network address to the storage system.

Download and install the Connection Utility software

Procedure

1. Download the Connection Utility installation program from the Dell EMC Online Support website (https://support.emc.com/products/39949), under the Downloads selection on the menu bar of the product page for your storage system.
2. Install the Connection Utility software on a Windows computer.

To use the Auto Discover method, install the Connection Utility on a computer in the same subnet as the storage system's management port.

1. Launch the Connection Utility.

In Windows: C:\Program Files\DELL EMC\Unity linkedUtility

Note

The Connection Utility automatically sets the displayed language based on the settings of the computer. To change the language displayed in the Connection Utility, select the language from the list under Change language:.

Run the Connection Utility

Before you begin

Obtain the following information:

• Serial Number: Unique identifier associated with the storage system (printed on a tag located on the system). This identifies your system when you use the Connection Utility to discover storage systems on a subnet. When you register your system online, this value is the Product ID.
• System name: Name that you will be assigning to the storage system.
• IP address: Management IPv4 or IPv6 address through which Unisphere connects to the storage system.
• Subnet mask: For IPv4 management addresses, the subnet mask is an IP address mask that identifies the range of IP addresses in the subnet where the storage system is connected.
• Subnet prefix length: For IPv6 management addresses, the subnet prefix length is the number of significant bits in the address that will be used for routing purposes.
• Gateway address: IP address of the default gateway for the management interface. The gateway is the IP address of the router or node used to communicate outside the local subnet.

Run the Connection Utility from a host attached to the same subnet as your storage system. Doing so lets the Connection Utility automatically detect the new storage system. If you are unable to run the Connection Utility from the same subnet, you can still manually configure the connection.

Procedure

1. On the Welcome screen, select one of the following methods to configure your system, and then click Next:

2. Auto Discover - Use this method if you are running the Connection Utility from a host on the same subnet as your storage system. This method automatically discovers unconfigured storage systems on your local network and sends the configuration file directly to the storage system.

3. Manual Configuration - Use this method if you are running the Connection Utility from a host that is not on the same subnet as your storage system. This method enables you to create a configuration file that you can save to a USB flash drive. You then insert the flash drive into the USB port on the storage system, and the storage system automatically reads the configuration from the USB drive.

4. [Applies to Auto Discover mode only] From the list of automatically discovered systems, select the system you want to configure, and then click Next. Note: If you do not see the system listed on the screen, try clicking Discover to restart the discovery process. If the problem persists, refer to troubleshooting instructions.

5. On the Configure screen, specify the following:

- Name - A meaningful name for this system. You can specify a name up to 32 characters. It can only contain alpha-numeric characters and a dash. It cannot contain any space characters, underscores, or begin and end with a dash.

- In the Management IPv4 Address and Management IPv6 Address sections, select the options you want, specify relevant information, and then click Next.

1. Review the configuration information, and then do the following based on the mode you selected:

2. For Auto Discover mode, click Start to apply the configuration on the storage system.
   • For Manual Configuration mode:

a. Click Save to USB drive. Ensure that you save the configuration file to the root directory level of the USB drive.
b. Click Next to identify the location of the port on your storage system.
c. Insert the USB drive into one of the available USB ports on either SP.

The storage system will automatically detect the USB drive and apply the network connection information. This process may take up to 10 minutes.

When successfully completed, a response file (iw_resp.txt) is written back to the USB drive.

1. Click Finish.
2. Confirm that the SP Fault LED is solid blue, which indicates that the system's IP address has been set.

After you finish

In a web browser, access Unisphere by specifying the URL: http:///.

Where, is the IP address you set for the storage system.

Note

Refer to the Configuration Worksheet for information on the user credentials you must use the first time you log on.

The Initial Configuration Wizard launches the first time you access Unisphere. Refer to the Configuration Worksheet and Unisphere Online Help for more information on configuring and start using your system.

Cabling the DPE to a DAE

If you have one or more DAEs, cable the DAEs to the DPE back-end ports so that the storage is available in the system.

Ensure that the DAE is located close enough to route and connect to the DPE using the two-meter DPE-to-DAE interconnect cables. Five-meter and ten-meter interconnect cables are available when connecting enclosures across multiple racks.

Note

General DAE back-end bus configuration rules:

1. Maximum number of enclosures per bus is 10.
2. Maximum number of drive slots per bus is 250, up to specific system limitations for drive slots.
3. For best performance, it is recommended that you evenly distribute DAEs across the available back-end buses.

Consider the maximum number of drives that can be installed in the storage system model. DAEs can be added to the system while the operating system is active, and up to the DAE and drive slot limit for the storage system. DAEs or drive slots that are over the system limit cannot operate in the system.

The storage processors connect to the DAEs with mini-SAS HD cables. The cables connect LCCs in the DAEs of a storage platform in a daisy-chain topology. The mini-SAS HD ports on the storage processors in the DPE are labeled 0 and 1. Mini-SAS HD port 0 is connected internally to the SAS expander that connects the drives on the front of the DPE.

Each DAE supports two redundant connections to the DPE: LCC A and LCC B.

It is recommended that you connect the first optional DAE to the mini-SAS HD output port 1 of each storage processor. This connection creates back-end bus 1 (BE1) and designates this DAE as enclosure 0 of this bus. The address of this enclosure is BE1 Enclosure 0. In a two back-end bus system, it is recommended that you connect the second optional DAE to the mini-SAS HD port 0 of each storage processor.

DAE load balancing

If your system has several optional DAEs, you can daisy-chain them within that bus. However, it is recommended that you balance each bus. In other words, optimize your environment by using every available bus, and spread the number of enclosures and

drives as evenly as possible across the buses. The rule of load or bus balancing is applied to all DAEs.

Cabling the first optional DAE to create back-end bus 1

Connect the first optional expansion DAE to port 1 of the DPE to create back-end bus 1 (BE1) and designate this DAE as enclosure 0 of this bus. We refer to the address of this enclosure as BE1 Enclosure 0 (1_0).

To prepare for this cabling task:

• Locate the mini-SAS HD cables to be used to connect to the newly installed expansion DAE. Typically these cables are two-meters long. You use longer cables, typically five-meters or eight-meters, to connect enclosures located in different racks. Cables are shipped without labels attached. The cables and ports are not colored.
• Locate the sheet of cable labels provided.

Orient the cable connectors as described in the procedure that follows, making sure that you do NOT connect:

• A DPE expansion port 0 to another DPE expansion port 0
• Any A-side ports to B-side ports

Procedure

1. Label a pair of mini-SAS HD cables.
2. Connect port 1 on SP A in the bottom slot of the DPE to port A on the link control card (LCC A) in the bottom of the DAE.
3. Connect port 1 on SP B in the top slot of the DPE to port A on the link control card (LCC B) in the top of the DAE.

Figure 22 Cabling one DPE to one 25-drive DAE

Cabling the second optional DAE to create back-end bus 0

Connect the second optional expansion DAE to the DPE expansion port 0 to extend back-end bus 0 (BE0) and designate this DAE as enclosure 0 of this bus. We refer to the address of this enclosure as BE0 Enclosure 0 (0_0).

Note

When cabling the 15-drive DAE LCC SAS ports, ensure that the cables do not overlap behind the DAE.

Procedure

1. Label a pair of mini-SAS HD cables.
2. Connect port 0 on SP A in the bottom slot of the DPE to port A on the link control card (LCC A) in the bottom of the DAE.
3. Connect port 0 on SP B in the top slot of the DPE to port A on the link control card (LCC B) in the top of the DAE.

If you need to cable more than two optional DAEs, refer to the Unity Installation Guide.

Cabling an expansion DAE to an existing DAE to extend a back-end bus

Connect the optional expansion DAE to the last installed DAE in the back-end bus to extend to the new DAE.

Note

When cabling the 15-drive DAE LCC SAS ports, ensure that the cables do not overlap behind the DAE.

Procedure

1. Label a pair of mini-SAS HD cables.

2. Connect port B on the link control card (LCC A) of the lower-numbered DAE to port A on the link control card (LCC A) of the higher-numbered DAE.

LCC A is on the lower portion of the DAE.

Safety precautions for handling replaceable units

Review these safety considerations before replacing any parts to avoid damage to your system.

• Handling replaceable units....122
• Standard touch point colors....125

Handling replaceable units

This section describes the precautions that you must take and the general procedures that you must follow when removing, installing, and storing any replaceable unit.

Avoiding electrostatic discharge (ESD) damage

When replacing or installing hardware units, you can inadvertently damage the sensitive electronic circuits in the equipment by simply touching them. Electrostatic charge that has accumulated on your body discharges through the circuits. If the air in the work area is very dry, running a humidifier in the work area will help decrease the risk of ESD damage. Follow the procedures below to prevent damage to the equipment.

Be aware of the following requirements:

• Provide enough room to work on the equipment.
• Clear the work site of any unnecessary materials or materials that naturally build up electrostatic charge, such as foam packaging, foam cups, cellophane wrappers, and similar items.
• Do not remove replacement or upgrade units from their antistatic packaging until you are ready to install them.
• Before you begin service, gather together the ESD kit and all other materials you will need.
• Once servicing begins, avoid moving away from the work site; otherwise, you may build up an electrostatic charge.

• Use ESD anti-static gloves or an ESD wristband (with strap). If using an ESD wristband with a strap:

• Attach the clip of the ESD wristband to the ESD bracket or bare metal on a cabinet/rack or enclosure.

• Wrap the ESD wristband around your wrist with the metal button against your skin.
  ■ If a tester is available, test the wristband.

Emergency procedures (without an ESD kit)

In an emergency when an ESD kit is not available, use the following precautions to reduce the possibility of an electrostatic discharge by ensuring that your body and the subassembly are at the same electrostatic potential.

NOTICE

These precautions are not a substitute for the use of an ESD kit. Follow them only in the event of an emergency.

• Before touching any unit, touch a bare (unpainted) metal surface of the cabinet/rack or enclosure.
• Before removing any unit from its antistatic bag, place one hand firmly on a bare metal surface of the cabinet/rack or enclosure, and at the same time, pick up the unit while it is still sealed in the antistatic bag. Once you have done this, do not

move around the room or touch other furnishings, personnel, or surfaces until you have installed the unit.

• When you remove a unit from the antistatic bag, avoid touching any electronic components and circuits on it.
• If you must move around the room or touch other surfaces before installing a unit, first place the unit back in the antistatic bag. When you are ready again to install the unit, repeat these procedures.

Hardware acclimation times

Systems and components must acclimate to the operating environment before applying power. This requires the unpackaged system or component to reside in the operating environment for up to 16 hours in order to thermally stabilize and prevent condensation.

Table 11 on page 123 helps you determine the precise amount of stabilization time required.

Table 11 Hardware acclimation times (systems and components)

If the last 24 hours of the TRANSIT/STORAGE environment was this:		...and the OPERATING environment is this:	...then let the system or component acclimate in the new environment this many hours:
Temperature Humidity
Nominal 68-72°F (20-22°C)	Nominal 40-55% RH	Nominal 68-72°F (20-22°C) 40-55% RH	0-1 hour
Cold <68°F (20°C)	Dry <30% RH	<86°F (30°C) 4 hours
Cold <68°F (20°C)	Damp ≥30% RH	<86°F (30°C) 4 hours
Hot >72°F (22°C)	Dry <30% RH	<86°F (30°C) 4 hours
Hot >72°F (22°C)	Humid 30-45% RH	<86°F (30°C) 4 hours
	Humid 45-60% RH	<86°F (30°C) 8 hours
	Humid ≥60% RH	<86°F (30°C) 16 hours
Unknown <86°F (30°C) 16 hours

NOTICE

• If there are signs of condensation after the recommended acclimation time has passed, allow an additional eight (8) hours to stabilize.
• Systems and components must not experience changes in temperature and humidity that are likely to cause condensation to form on or in that system or component. Do not exceed the shipping and storage temperature gradient of 45^ F/hr ( 25^ C/hr).
• Do NOT apply power to the system for at least the number of hours specified in Table 11 on page 123. If the last 24 hours of the transit/storage environment is unknown, then you must allow the system or component 16 hours to stabilize in the new environment.

Removing, installing, or storing replaceable units

Use the following precautions when removing, handling, or storing replaceable units:

CAUTION

Some replaceable units have the majority of their weight in the rear of the component. Ensure that the back end of the replaceable unit is supported while installing or removing it. Dropping a replaceable unit could result in personal injury or damage to the equipment.

NOTICE

• For a module that must be installed into a slot in an enclosure, examine the rear connectors on the module for any damage before attempting its installation.
• A sudden jar, drop, or even a moderate vibration can permanently damage some sensitive replaceable units.

- Do not remove a faulted replaceable unit until you have the replacement available.

- When handling replaceable units, avoid electrostatic discharge (ESD) by wearing ESD anti-static gloves or an ESD wristband with a strap. For additional information, refer to Avoiding electrostatic discharge (ESD) damage on page 122.

- Avoid touching any exposed electronic components and circuits on the replaceable unit.

- Never use excessive force to remove or install a replaceable unit. Take time to read the instructions carefully.

- Store a replaceable unit in the antistatic bag and the specially designed shipping container in which you received it. Use the antistatic bag and special shipping container when you need to return the replaceable unit.

- Replaceable units must acclimate to the operating environment before applying power. This requires the unpackaged component to reside in the operating environment for up to 16 hours in order to thermally stabilize and prevent condensation. Refer to Hardware acclimation times on page 123 to ensure the replaceable unit has thermally stabilized to the operating environment.

NOTICE

Your storage system is designed to be powered on continuously. Most components are hot swappable; that is, you can replace or install these components while the storage system is running. However, the system requires that:

• Front bezels should always be attached to ensure EMI compliance. Make sure you reattach the bezel after replacing a component.
• Each slot should contain a component or filler panel to ensure proper air flow throughout the system.

Unpacking a part

Procedure

1. Wear ESD gloves or attach an ESD wristband to your wrist and the enclosure in which you are installing the part.
2. Unpack the part and place it on a static-free surface.
3. If the part is a replacement for a faulted part, save the packing material to return the faulted part.

Standard touch point colors

Touch points are component locations where you can:

• Grip the hardware to remove or install a component.
• Open or close a latch.
• Turn a knob to open, close, or adjust a component.

Standard touch point colors are terra-cotta (orange) or blue.

Note

Within this documentation, the color orange is used instead of terra-cotta for simplicity.

Table 12 Standard touch point colors

Touch point color	Description
Terra-cotta(orange)	This color indicates that you can perform the task, such as remove a component with a terra-cotta (orange) lever, while the system remains powered (up/on).NoteSome tasks may require additional steps.
Blue This color indicates that a shutdown of the system or component is required before you can perform the task, such as removing a component with a blue lever.
