Abstract. In an IaaS (Infrastructure-as-a-Service) cloud services, storage needs of VM (Virtual Machine) instances are met through virtual disks (i.e. virtual block devices). However, it is nontrivial to provide virtual disks to VMs in an efficient and scalable way for a couple of reasons. First, a VM host may be required to provide virtual disks for a large number of VMs. It is difficult to as...

background: biting habit of mosquitoes plays an important role in the epidemiology of mosquito-borne diseases. mosquitoes use a set of elaborate sensory modalities to find their preferred hosts by exploiting cues emanating from a nearby host. it has been suggested that the chemical profile of skin can provide further support for anthropophilic mosquito species to find their suitable hosts. this...

Remote mirroring ensures that all data written to a primary storage device are also written to a remote secondary storage device to support disaster recoverability. In this study, we designed and implemented a storage-based synchronous remote mirroring for SAN-attached storage nodes. Taking advantage of the high bandwidth and long-distance linking ability of dedicated fiber connections, this ap...

Executive Summary Direct PCI Express (PCIe) attached flash storage offers unparalleled performance levels and vastly outperforms SAS/SATA-attached flash storage solutions. However, such PCIe attached flash storage cards, in their existing form, are restricted to the confines of the PCIe slots in the host server. This approach can neither support a disaggregated storage (JBOD/RAID-like) mode tha...

Applications increasingly combine cloud storage, edge caches, and local storage to host and share data. They do so, however, in ad-hoc ways, producing a landscape of point solutions that solve similar problems. This paper describes an alternative approach that composes storage systems in a general, but configurable way. The resulting system, called Syndicate, factors out data consistency, syste...

Survival of two British steinernematids, one a strain of Steinemema feltiae (Filipjev) [ = S. bibionis (Bovien)], and the other an undescribed species designated Steinernema sp. (Nashes strain) was assessed after storage of infective juveniles in sterile sand at 5 "C and 15 "C and was measured by their motility (ability to be extracted by mini Whitehead trays). Infectivity after storage at the ...

Proof-Carrying Code (PCC) allows a code producer to provide to a host a program along with its formal safety proof. The proof attests a certain safety policy enforced by the code, and can be mechanically checked by the host. While this language-based approach to code certification is very general in principle, existing PCC systems have only focused on programs whose safety proofs can be automat...

Today, an SSD (Solid State Drive) is essentially a block device attached to a legacy host interface. As a result, the system I/O bus remains a bottleneck, and the abundant flash memory bandwidth as well as the computing capabilities inside SSD is largely untapped. In this paper, we motivate an efficient in-storage computing approach where (part of) data-intensive processing is moved from the ho...

Metal-organic frameworks (MOFs) are potentially useful materials for hydrogen and methane storage. However, the weak interactions between the MOF host and gas guest molecules have limited their storage capacities at elevated temperatures. In this issue, Alkordi et al. [IUCrJ (2017), 4, 131-135] illustrate an example of a porous MOF with a suitable pore size and unique pore surface for enhanced ...
