+\begin{abstract}
+
+Cloud@CNAF is  the cloud infrastructure hosted at CNAF, based on open source solutions aiming
+to serve different use cases present here.  The infrastructure is the result of  
+the  collaboration  of  a  transversal  group  of  people  from  all  CNAF  
+functional units:   networking, storage, farming, national services, distributed systems.  
+If 2016 was for the Cloud@CNAF IaaS (Infrastructure as a Service) based on OpenStack, 
+a period of consolidation and improvement, 2017 was an year of consolidation and 
+operation ended with an extreme event - the flooding of the DataCenter, when an 
+aqueduct pipe located in the street nearby CNAF went broke. This event caused 
+down of the entire DataCenter, including the Cloud@CNAF infrastructure.This paper 
+presents the activities carried out throughout 2018 to ensure the functioning
+of the center cloud infrastructure, that saw the its migration from CNAF to INFN-Ferrara, 
+starting to the re-design of the entire to cope with the limited availability of 
+space and weigth imposed by the new location, to the physical migration of the 
+racks and remote management and operation of infrastructure in order to continue 
+to provide high-quality services for our users and communities. 
+\end{abstract}
+
+\section{Introduction}
+The main goal of Cloud@CNAF \cite{catc} project is to provide a production quality
+Cloud Infrastructure for CNAF internal activities as well as national and
+international projects hosted at CNAF:
+\begin{itemize}
+  \item Internal activities
+    \begin{itemize}
+    \item Provisioning VM for CNAF departments and staff members
+    \item Tutorial and courses
+    \end{itemize}
+  \item National and international projects
+    \begin{itemize}
+      \item Providing VMs for experiments hosted at CNAF, like CMS, ATLAS, EEE and FAZIA
+      \item testbeds for testing the services developed by projects like the INDIGO-DataCloud, eXtreme-DataCLoud and DEEP-HybridDataCloud
+    \end{itemize}
+\end{itemize}
+
+The infrastructure made available is based on OpenStack \cite{openstack}, version Mitaka, with all the
+services deployed using a High-Availability (HA) setup or in a
+clustered manner (for ex. for the DBs used). During  2016 the infrastructure has been
+enhanced, by adding new resources, compute and network, and its operation has been improved and guaranteed by
+adding the monitoring part, improving the support, automating the maintenance activities.
+
+Thanks to this enhancement, Cloud@CNAF was able to offer high reliable services to the users and communities who rely on such infrastructure.
+
+At the end of 2017, on November 9th early at morning, an aqueduct pipe located in the street nearby CNAF, broke as documented in Ref. \cite{flood}.  
+As a result, a river of water and mud flowed towards the Tier1 data center.  The level of the water did not exceeded the 
+threshold of safety of the waterproof doors but, due to the porosity of the external walls and the floor, it could find a way
+ into the data center. Both  electric  lines  failed  at  about  7.10AM CET.   Access  to  the  data  center  was  possible  only 
+ in the  afternoon,  after  all  the  water  had  been  pumped  out.
+As a result, the entire Tier1 data center went down, included the Cloud@CNAF infrastructure.
+
+
+\section{The resource migration}
+Some weeks after the flooding, has been decided to move the Cloud@CNAF core services in a different location
+in order to recover the services provided for communities and experiments.
+Thanks to a strong relationship, both University of Parma/INFN-Parma and INFN-Ferrara proposed to host our 
+core machinery and related services.
+Due to the geographical proximity and the presence of Point of Presence (PoP) GARR, the 
+Cloud@CNAF core machinery was moved to the INFN-Ferrara location.
+
+Unfortunately, we were not able to move all the Cloud@CNAF resources due to a limited power and weight availability in the new location.
+For the above mentioned reason, the re-design of the new infrastructure has been considered.
+As a first step, the services and the related machinery to move to the new - temporary - location have been selected in order to
+ fit the maximum power consumption and weight estimated for each of the two rooms devoted to host Cloud@CNAF services (see Table \ref{table:1} for details).
+
+\begin{table} [ht]

+\begin{tabular}{ l|c|c|c||c||c| } 
+\cline{2-6}
+ & \multicolumn{3}{c||}{Room1}  &  Room2 & Tot \\
+\cline{2-5}
+ & Rack1 & Rack2 & Tot &  Rack3 &  \\
+\hline
+Power consumption (kW) & 8,88 &  4,91 & 13,79 (15) & 5,8 (7)& 19,59\\ 
+Weight (Kg) & 201 & 151 & 352 (400Kg/mq) & 92 (400Kg/mq) & 444 \\ 
+Occupancy (U) & 9 & 12 & 21 & 10 & 31 \\ 
+\hline
+\end{tabular}
+\caption{Power consumption weight and occupancy for each Rack. In brackets, the maximum value admitted for the Room.}
+\label{table:1}
+\end{table}
+
+\section{Re-design the new infrastructure}
+Due to the limitations described in Table\ref{table:1} only three racks have been used to host Cloud@CNAF core service.
+Among this three racks, the first hosts the storage resources, the second hosts the Openstack controller, the network
+ services and the GPFS cluster. The third hosts Ovirt and Openstack compute nodes, together with
+ some other ancillary services  (see Table \ref{table:2} for details).
+Rack1 and Rack2 have been connected by 2x40Gbps through our Brocade VDX switches and Rack1 and Rack3 have been connected 
+by 2x10Gbps through PowerConnect switches.
+
+\begin{table} [ht]
+\centering
+\begin{tabular}{ c|l|l|l| } 
+\cline{2-4}
+& \multicolumn{1}{|c|}{Rack1} & \multicolumn{1}{|c|}{Rack2} & \multicolumn{1}{|c|}{Rack3}\\
+\hline
+& VDX & VDX &  PowerConnect x2 \\ 
+Resources & EqualLogic & Cloud controllers &  Ovirt nodes\\ 
+and & Powervault & Cloud networks & Compute nodes\\
+Services & & Gridstore & DBs nodes\\
+& &  Other services & Cloud UI\\
+\hline
+\end{tabular}
+\caption{List of resources and services hosted per Rack}
+\label{table:2}
+\end{table}
+
+Moreover, Rack1 is connected to PoP GARR with 1x1Gbps fiber connection to guarantee external connectivity.
+A complete overview of the new infrastructure and related resource location is shown in Figure \ref{new_c_at_c}.
+As depicted from the Figure \ref{new_c_at_c}  and taking into account the limitations described in Table \ref{table:1}) the power consumption
+has been limited  up to 13,79kW in respect to Room1 (limit 15kW) and up to 5.8kW (limit 7kW) in respect to Room2.
+
+The whole migration process (from the design to the reconfiguration of the new infrastructure) took just a business week 
+and after that the Cloud@CNAF infrastructure and related services where up and running, able to serve again different projects and communities.
+
+Thanks to the experience and documentation gathered, in June 2018 - after the Tier1 returned in its production status, 
+Cloud@CNAF has been migrated back in less than three business days.
+
+\section{Cloud@CNAF evolution}
+
+Starting from the activity carried out in 2016 related to the improvements done at the infrastructure level \cite{catc}, in 
+2018 (after the return of the core infrastructure services due to the flooding) 
+the increase of the computing  resources, in terms of quality and quantity, continued in order to enhance both the
+ services and the performance offered to users.
+
+Thanks to such activity, during the last year the Cloud@CNAF saw a growth on the number of users and use cases
+ implemented in the infrastructure, in particular the number of projects increased up to 87 using approximately 
+ 1035 virtual CPUS, 1.766TB of RAM, with a total of 267 virtual machines (see Figure \ref{catc_monitor} for more details).
+
+Among others, some of the projects that used the cloud infrastructure are: 
+\begin{itemize}
+\item HARMONY - Proof-of-concept under the TTLab coordination, is a project aimed at finding resourceful medicines offensive against neoplasms in hematology,
+\item EEE - Extreme Energy Events - Science inside Schools (EEE), is a special research activity about the origin of cosmic rays carried out with the essential contribution of students and teachers of high schools,
+\item CHNET-DHLab - Cultural heritage network of INFN for the development of virtual laboratories services, 
+\item USER Support - for the development of experiments dashboard and the hosting of the production instance of the dashboard, displayed on the monitor present on the CNAF hallway,
+\item EOSC-hub DODAS - Temaic service for  Elastic  Extension  of  Computing  Centre  batch resources  on  external  clouds,
+\item Services devoted to EU projects like DEEP-HDC \cite{deep}, XDC \cite{xdc} and EOSC-pilot \cite{pilot}.
+\end{itemize}
+
+
+
+\section{Conclusions and future work}
+Due to a damage in the aqueduct pipe located in the street nearby CNAF, a river of water and mud flowed towards the Tier1 data center causing the 
+shutdown of the entire data center. For such reason, the services and related resources hosted by Cloud@CNAF went down.
+To cope with this problem, the decision to temporary migrate the core resources and services of Clud@CNAF to INFN-Ferrara has been taken and adopted.
+In order to do this, a complete re-design of the entire infrastructure was needed to tackle the limitations in terms of power consumption and
+ weight imposed by the new location.
+The joint effort and expertise of all the CNAF people and the INFN-Ferrara colleagues made possible to re-design, migrate and make operational 
+the Cloud@CNAF infrastructure and related hosted services in less than a business week.
+Thanks to the experience and the documentation gathered, in June 2018 - after the Tier1 returned in its production status, Cloud@CNAF 
+has been migrated back in less than three business days.
+Even with the above described problems, the Cloud@CNAF infrastructure has been maintained and evolved, giving the possibility 
+to the users to carry on their activities and obtain their desidered results.
+For the next year new and challenging activities are planned, in particular the migration to the OpenStack Rocky version and the deployment of a new architecture distributed between 
+differnet functional units, Data Center and SDDS.
