    … …  
    1818=== ESB nodes ===
    1919
    20 - in CW51 the update of the first ESB rack started for using Extoll Fabri3 network (instead of IB)
    21   - work is still ongoing
     20- the first ESB rack (nodes `dp-esb[01-25]`) is planned to be revised to use IB again (instead of Extoll interconnect)
     21  - date for the HW intervention not yet fixed
    2222
    2323=== DAM nodes ===
    2424
    25 - first 8 DAM nodes (dp-dam[01-08]) are currently being integrated into Extoll Fabri3 network
    26  
    27 - Persistent memory for nodes dp-dam[03-16] has been extended to 3 TB with next maintenance (CW51)
     25- along with first ESB rack also the DAM nodes will move to IB (instead of using 40 GbE and Extoll)
    2826
    2927=== Network Federation Gateways ===
    3028
    31 - Gateway nodes have been completed in CW51 to the final layout:
     29- with aiming for an "all IB" solution the NFGWs will become obsolete
    3230
    33   * 2x NF-GW EDR/Extoll (1 x Fabri3, 1 x Tourmalet)
    34 
    35   * 2x NF-GW 40GbE/Extoll ( 1 x Fabri3, 1 x Tourmalet)
    36 
    37   * 2x NF-GW EDR/40GbE
    38 
    39 - **due to the ongoing Fabri3 installation two of the NF-GWs (the ones equipped with Fabri3 PCIe cards) are not in operation yet**
    40 
    41 - for an example on how to use the gateway nodes and for further information,
    42   please refer to the [wiki:/Public/User_Guide/Batch_system#HeterogeneousjobswithMPIcommunicationacrossmodules batchsystem] wiki page.
     31- current status is
     32  - 2x NF-GW EDR/Extoll (1 x Fabri3, 1 x Tourmalet)
     33  - 2x NF-GW 40GbE/Extoll ( 1 x Fabri3, 1 x Tourmalet)
     34  - 2x NF-GW EDR/40GbE
     35  - the NF-GWs equipped with Fabri3 PCIe cards are not in operation
     36  - for an example on how to use the gateway nodes and for further information,
     37    please refer to the [wiki:/Public/User_Guide/Batch_system#HeterogeneousjobswithMPIcommunicationacrossmodules batchsystem] wiki page.

    … …  
    4843
    4944- a NAM SW implementation has been done, a test environment on the DAM has been set up on dp-dam[09-16].
     45- for more information on NAM usage and an example, please refer to [wiki:Public/User_Guide/TAMPI_NAM NAM with TAMPI] page
    5046
    5147=== File Systems ===
    5248
    53 - **a new All Flash Storage Module (AFSM) is going to be added to the system on 24./25. February**
     49**please refer to the**  [wiki:Filesystems Filesystems] **overview**
    5450
    55 - DEEP-EST storage has been rebuilt for performance reasons
     51- recent changes:
     52  - a new All Flash Storage Module (AFSM) is in place and provides fast work file system mounted to `/work` on compute nodes and login node (`deepv`)
     53    - the older System Services and Storage Module (SSSM) still serves the /usr/local file system
     54    - SSSM storage has been rebuilt for performance reasons
    5655  - BeeGFS servers and clients have been updated
    57   - the SDV is de-coupled now meaning that the SDV nodes do not mount `/work` anymore and the DEEP-EST (CM,DAM,ESB) nodes only mount `/work` (not `/sdv-work`)
    58 
    59 - BeeGFS (`/work`) user quotas is in place now (see section "User management")
    60 
    61 - It is possible to access the `$ARCHIVE` file system from the `deepv` login node under `/arch`. For more information about `$ARCHIVE`, please refer to the [wiki:Filesystems Filesystems page] and see also
    62   the hint in the MOTD for efficient usage of the archive filesystem
    63 
    64 - DCPMM usage within BeeGFS has successfully been tested on `dp-dam03` using a 4.19 kernel
     56  - BeeGFS (`/work`) user quotas is in place now (see section "User management")
     57  - It is possible to access the `$ARCHIVE` file system from the `deepv` login node under `/arch`. 
     58    See hint in the MOTD for efficient usage of the archive filesystem
