What is the difference between ESRS IP client and ESRS GW?

Jump to solution

Hello,

I open this discussion to clear some points.

If I understand correctly ESRS GW and ESRS IP Client are two different SWs.

What is the difference between ESRS IP client and ESRS GW?

I have installed ESRS GW. It is monitored DMX box.

Is it needed to install ESRS IP over ESRS GW machine to monitor clarion CX box?

I admit the naming convention is a little confusing.  When the ESRS product was first introduced in January 2006, it was called EMC Secure Remote Support Gateway or ESRS Gateway.  We sometimes refer to it as ESRS 1.  It was a general purpose solution that supported most of the EMC products available.  The second generation of the product (ESRS 2) was introduced in July 2010 and the name was changed to EMC Secure Remote Support IP Solution or ESRS IP Solution.  The idea was to refer to ESRS 1 as ESRS Gateway and ESRS 2 as ESRS IP Solution.  In actuality, most people refer to the current product as ESRS Gateway and that's probably from habit and to differentiate between it and the later products that were introduced with "IP Client" in their names. 

The ESRS IP Client for CLARiiON was introduced in July, 2010 and was designed to only manage CLARiiON devices.  The ESRS IP Client for VNX was introduced later and manages legacy CLARiiON and VNX.  We have since released ESRS Device Client for Symmetrix and VNXe Device Client.  The device clients are designed to manage a single product.

Since you already have the ESRS Gateway, it would not be necessary to install the IP Client for CLARiiON/VNX.

Hi James,

Thank you for fast response and detailed explanation! It is clearer now! But I have another question about each device clients. Here is the current example:

I have an environment with few CX3/4 boxes, Celerra, DD two DMX3 and old DMX1000. At the moment I have installed EMC Secure Remote Support – IP Solution Gateway Client (PN 953-002-303). It was ordered and installed. All my boxes except DMX1000 are added and listed in tab “Managed devices” in ESRS configuration tool. 

So if I understand correctly this ESRS client is only for DMX, isn’t it? In this case why I am able to add and other devices?

Is it needed to install additional ESRS client for CX boxes? If it is needed may I install it on the same windows machine as my current ESRS?

Thank you in advance!

Regards

Kiril

Just to clarify, the ESRS Device Client is for VMAX arrays.  It is integrated in to systems with 587x code only.  However the full version of ESRS IP Solution does work for DMX arrays.  For reference, the ESRS Technical Description document provides listings of all systems supported.

Response:

DMX does NOT use a device client on the SP  it is ONLY supported on ESRS Gateway. You need to engaged your CE to configure the DMX to use the ESRS Gateway  and to get it deployed.

The CX boxes can be managed via  ESRS Gateway(s). If you wish to use the Clariion/ VNX tool to anage your storage do NOT attempt to install them on the Gateways server this is an unsupported configurations and will " wipe out " the ESRS Gateway  and the Celerra and DD will become unmanaged ( unable to connecthome or EMC to connecto for support) Clarrion / VNX Management Station with ESRS Device Client is limited to managing VNX Block, File, Unified , VG2& VG8 , and Legacy Clariion. Id does NOT suppport Legacy Celerra or any other EMC products

Hi Kiril,

ESRS IP Client for VNX is more than just connectivity it contains additional functionality that are specific to the VNX-Block and CLARiiON products, but it only supports these products. The ESRS Gateway is ONLY for connectivity and cannot have the additional functionality added, but it does support all the products in your environment.

With your suggested product mix I would recommend:

The ESRS Gateway (v2) to support all of your products for connectivity. I would additionally recommend you install the ESRS IP Client for VNX on a separate server/vm to provide you with the additional functionality that only this product can offer. The ESRS Gateway must be installed by an EMC CE and technically the ESRS IP Client for VNX can be installed by customers and partners, but in this configuration I would recommend that the EMC CE set this up for you.

what is this extra functionality that you get with ESRS IP Client for VNX ? I have ESRS Gateway v2 in my environment at the moment.

Hi dynamox,

ESRS IP Client for VNX contains:

UDoctor which is made up of Array Health Analyzer (AHA), Triage Real Time (TRT) and Triage on Management Station (TOMS). Details on PowerLink: Home > Support > Software Downloads and Licensing > Downloads C > CLARiiON CX3-80

UDoctor pre-filters errors and only opens up a Service Request for errors that EMC needs to know about. The tool also runs log capture tools like SPCollect automatically when certain errors occur so the lab can diagnose issues much quicker.

Automated Periodic Array Configuration Capture and Upload Tool (ACU) - KnowledgeBase: emc211316

ACU has been around since 2009 and support all CLARiiON's and the VNX-Block and it collects config information from the product which can then be used by support to determine part number and serial numbers in the machine. For example if a drive fails on occasion is hard fails to the point that even with a connect in from the lab that can't determine the drive type which often requires the customer to confirm physically. If ACU data is available, EMC could determine the drive part number from the last config home.

The third and obvious capability is connectivity, but unlike the ESRS Gateway product it also supports email home and modem home for customers still using these older technologies as well as ESRS of course.

Something to keep in mind as well if the Gateway is Version 2.16.xx.xx it has a feature ( SRS Gateway Proxy ) which can be leveraged by Device Clients to permit use of the customers firewall for  Gateway configuration for the communication to EMC so they can take advantaqge of any special features  available on the ESRS device Client. This is done by pointing the ESRS Device Client to hte Gateway on port 8118 in the proxy settings. Thhe Gateway and ESRS Device Clients can / should be configured to use the dsame Policy Manager. Note the Device Client and it managed devices ( in the case of VNX/Clariion Managemnt station are NOT deployed on the ESRS Gateway ). One of the advantages of the VNX/ Clariion Management station is that device deployment is fully automatic where device deployment on a Gateway requires EMC approval for final deployment

Trefor,

sounds like you are automating some of the things that otherwise would require support person to connect via ESRS and do it themselves (like initiate spcollects ..etc). So for me as a customer is it worth investing into yet another Windows 2008 license and VMware license to stand up another VM ...i am not convinced. If you are going to say that this will expedite the process of managing the hardware i am going to laugh because we've had ESRS for over 3 years now and i still get calls from Clariion/VNX support trying to schedule Webex for drive replacement.
