If you’re looking to archive several petabytes of data, you might want to consider the new EMC Isilon HD400 node. It’s the biggest of the current Isilon nodes in terms of size—you can store up to 354 TB of data on 59 hard drives using a 4U rack space.

To learn more about the external and internal components of the HD400 node, watch the video, Decode the Node: EMC Isilon HD400.

HD400 and OneFS 7.2

The HD400 node was released with the Isilon OneFS operating system 7.2. The OneFS 7.2 release provides support for the following items required for the HD400:

  • New protection levels: New requested protection levels are available in OneFS 7.2 to account for the increased capacity of HD400 nodes. For example, the default protection level for node pools on the HD400 node is “3d:1n1d,” which means that data is protected in case 3 drives fail or if 1 node and 1 drive fail.
  • L3 cache: The HD400 node includes 800 GB of solid-state drive (SSD) storage, which is primarily used for L3 cache. This helps to reduce cache cycling times to improve system performance. For more information, see the L3 Cache Overview topic in the OneFS 7.2 Web Administration Guide or OneFS 7.2 CLI Administration Guide.
  • New drive layout: Disks in the HD400 are arranged in a grid orientation because the drives are inserted top-down into the node chassis. To view the new grid orientation in the OneFS 7.2 web administration interface, go to Dashboard > Cluster Status and click on the ID number. This will take you to the Node Status view, where you can scroll down to view the grid orientation.

With EMC® Isilon® scale-out storage, it’s easy to add performance and capacity to your cluster simply by adding new nodes. For example, after you acquire a new node, a certified technician locates an open space in a rack (either 2U or 4U, depending on the node size), installs rails, installs the node into the rack, connects the network and InfiniBand cables, and then joins the node to the cluster. After joining the node, you’ll have more space and performance capacity right away.EMC Isilon 4U rail kit installation

The node installation process is simple and fast; but be sure to take the time to check that the nodes are safely secured to the rails and rack to minimize the risk of personal injury and damage to equipment.

Check out the following videos, which show the proper procedures for racking EMC Isilon 2U and 4U nodes, including both node installation and node removal from a rack.

Installing a node into a rack

Isilon nodes mount in a standard 19-inch wide rack and use a sliding rail system. Watch the following videos to learn how to install 2U and 4U nodes into a standard rack with 3/8-inch square holes.

For written descriptions of these procedures, see the EMC Isilon 2U rail kit installation guide and 4U rail kit installation guide, which are available on the EMC Online Support site (login is required).

Removing a node from a rack

If you need to remove nodes from the rack to service them or because you’re relocating your cluster, it’s important to be sure that you always shut down nodes as described in the knowledge base article, How to safely shut down an Isilon cluster prior to a schedule power outage (16529). If you don’t shut down a node properly, you increase the risk of data loss.

After the node is shut down, you can remove a 2U node and a 4U node from a rack. Watch the following videos to learn the safest way to remove these nodes from a rack.

For written descriptions of these procedures, see the node removal guides on the EMC Online Support site.

Decode our new EMC Isilon nodes: S210 and X410

[Editor’s note: Two corrections about the number of serial ports and the front panel light were made to the original Decode the Node videos published on 7/31, and both videos were republished on 8/18 and 8/19. This article was updated to include links to the latest videos.]

Earlier this month, we announced the availability of two next generation EMC® Isilon® nodes: the S210 node for ultra-fast primary storage and high IOPS applications, and the X410 node to handle high-concurrent and sequential-throughput applications.

To become better acquainted with these Isilon nodes, we have new videos where we decode the Isilon S210 node and the Isilon X410 node. Each video provides the node’s basic specifications, and shows you what all of the node’s components look like, inside and out, including:

  • Front of the node, with and without the front panel
  • Back of the node illustrating power supplies, power button, LEDs, and each connection port
  • Inside of the node

Wonder what’s inside the node?

We show you all the components located inside the node to satisfy your curiosity and increase your understanding about what makes the node run. We open the node for you, because the node must never be opened unless by an EMC certified Customer Support Engineer.

Sometimes node parts have to be replaced. For example, if EMC Isilon Technical Support determines that an external part has failed (such as a power supply, a hard drive, or the node’s front panel) and the node does not need to be opened, they will send a new part and you can replace the part yourself. If an internal node component fails (such as a PCIe card, DIMMs, or a fan) and the node needs to be opened, then only an EMC certified Customer Support Engineer may open the node to replace this type of component. You should never open the node and replace internal components yourself. Isilon Technical Support will schedule the replacement procedure for an internal part at your convenience.

For more information, watch the videos below.

To learn more about the S210 or X410 nodes, see the EMC Isilon S-Series spec sheet or the EMC Isilon X-Series spec sheet.

You can find the S210 node installation guide and X410 node installation guide on the ECN Isilon Community (login with an ECN Community account is required).  Or visit the EMC Online Support site for more X410 and S210 node documentation (login with EMC Online Support account is required).

Video Transcript

Hello. I’m André Morrissen, a Senior Technical Writer at EMC.

Before you can log a case with EMC Isilon Technical Support, you’ll need to obtain the serial number of the affected nodes.

In this video, we’ll show you how to obtain a serial number from the physical node, using the EMC Isilon OneFS web administration interface, or using the OneFS command-line interface.

First, let’s look at how the format of serial numbers depends on the type of node.

For the current generation of EMC Isilon storage nodes, which include the S200, X200, X400,

NL400, serial numbers begin with the letter “S”, followed by the family code, the chassis code, the generation, and lastly, a ten-digit number.

The following example illustrates a serial number for an X200 node.

The serial number for an A100 performance or backup accelerator node starts with FC61S, followed by 9 digits, as seen in the following example.

For legacy Isilon IQ-Series nodes, the serial number format depends on the age of the node.

For newer IQ-Series 2U nodes with 12 drives and 4U nodes with 36 drives, serial numbers start with a letter that designates the node type:

“A” for accelerator nodes

“D” for EX storage expansion nodes

And “G”, “K”, “M”, or “R” for standard storage nodes

Nine digits follow the letter and the serial number ends with an “L”, as seen in the following example.

Serial numbers for older IQ-Series 2U nodes with 12 drives start with eight digits and end with the letter “S”.

Now let’s look at the three ways to find your node’s serial number.

If you have access to the physical node, the serial number is printed on a sticker.

For most nodes, the sticker is on the back of the node.

For A100 accelerator nodes, first remove the face plate from the front of the node.

Press both latches in simultaneously until they click, then remove the face plate.

Locate the black plastic tab on the top left of the node and slide it out.

The serial number is printed on the blue label.

When you’re done, slide the tab back in and replace the face plate.

First, log in to the OneFS web administration interface.

The Cluster Status page displays by default. If you’re on a different page, you’ll need to navigate there.

If you’re running OneFS 6.5 or earlier, click Status, then click Cluster Status.

If you’re running OneFS 7.0 or 7.1, click Dashboard, Cluster Overview, then click Cluster Status.

We’ll continue this demonstration using OneFS 7.1.

The Status section lists all the nodes in your cluster and their node numbers.

Locate the number for the affected node in the ID column and click it to view the information for that node.

The Node Status tab identifies the serial number along with other information for that node.

First, open an SSH connection on any node in the cluster and log in using the “root” account.

Then, run the following command to display information for all nodes in your cluster: isi_for_array -s isi_hw_status -i

Each line of output starts with the cluster name, followed by the node number. The output is displayed per node in numerical order.

For example, this block of output is for node 3 in the cluster.

Locate the serial number for the affected node.

For a written description of how to find node serial numbers, see the following knowledgebase article.

If you need assistance with this procedure, contact EMC Isilon Technical Support.

Thanks for watching.
